Meliodas


 * For the character in the original oneshot, see Meliodas (Oneshot)

"I've resolved to find the Seven Deadly Sins with you and stop the Holy Knights. Even if you were to die, I would fulfill the promise made with you."

- Meliodas to Elizabeth in Even If You Were To Die

is the leader of the Seven Deadly Sins and the Sin of Wrath with the symbol of the Dragon. He is the main protagonist of Nanatsu no Taizai and also the owner of Boar Hat.

Appearance
Despite having the appearance of a child, Meliodas is actually much older, being at least two-hundred years old. He is exceptionally short compared to other characters, with messy blond hair and a pair of emerald green eyes. He also lacks facial hair, further accentuating his adolescent appearance. Regardless of his stature and youthful looks, he is relatively muscular, possessing an array of well-developed abdominal muscles. He is often shown wearing an ordinary, clean white button-front shirt and a black sleeveless vest on top with a loosely worn tie. His broken sword's scabbard is held on by a green leather belt with gold-colored buckles. Without any socks, he wears a pair of black boots. His most distinctive trait is his Dragon symbol carved at the top of his left arm, just below his shoulders.

In his time as a Danafor Holy Knights' leader, Meliodas wears a traditional armor of Danafor's Holy Knights much like Cain's. Ten years ago, he wears full-body silver armor with a unique helmet like the rest of the Sins. He also wield a dagger that appeared to be his Sacred Treasure. The image on Meliodas' wanted poster, which does not resemble him at all, displays a much older man.

Personality
Meliodas's dominant traits are his frankness and his utter fearlessness, shown when he remains composed seeing the Rust Knight. Due to his horrible cooking, when his customers vomit onto the Boar Hat's floor, he instructs Hawk to clean up the scraps, and scares him by saying phrases such as "roast pig" if he complains, hinting he may roast the talking pig. He is also shown to be very bawdy and loves to frequently tell jokes. Occasionally, he takes advantage of Elizabeth's naivety and gropes her breasts, not even ashamed of doing so in public or in front of her father. He also has a strong sense of justice and is willing to help persons in distress. Even when he is severely injured, he tries not to show his weaknesses, and stays strong in front of his companions.

Despite his title as the Sin of Wrath, he appears to be a very calm person. However, if his companions or friends are harmed in any way, he is greatly angered. He is also shown to fall into a state of extreme rage when someone tries to take his sword, with this rage being capable of scaring even a Holy Knight and leaving a permanent scar on Ban's neck, despite his regeneration abilities. It has been hinted that Meliodas is guilt-ridden over the fate of Danafor, saying that his sin was being unable to save the kingdom. Ban and Cain point out that Meliodas tends to be soft and naive, due to him never killing anyone, even someone like Guila who was a serious threat to the group. Meliodas dislikes killing, preferring to be merciful. Elizabeth points out that Meliodas is not naive or a simpleton, but just really kind.

Meliodas appear to have a dark side personality when he used the Black Mark on his forehead when in trouble. When Meliodas use the Mark, the latter end up being cold, quiet, ruthless, and murderous as he killed and attacked anyone near to him and no longer merciful. However, for some reason he end up not killing Elizabeth, possibly due to her appearance of Liz who was his lover. Despite being known as a womanizer to most people, Meliodas seem to be truly perverted when Elizabeth or Liz are involved, but still crack dirty jokes and telling woman three sizes.

History
Meliodas' past is currently unknown as he seems to be unable to age over the years. At some point in time, Meliodas was spotted among the group of knights investigating an attack on a small village after seeing its smoldering ruins and witnessed King's arrest. At that time, Meliodas was a knight of another Kingdom.

Meliodas once came from the kingdom of Danafor where he was the leader of the Holy Knights. When a slave girl named Liz who came from the enemy kingdom came to Danafor for an ambush mission, Liz was then captured by the knights and was sentenced to death, but Meliodas set her free and personally offered to fight on her behalf if anyone objected. Meliodas later took Liz to his house where they lived together, often groping her chest to which she reacted violently. Later, Liz grew closer to Meliodas and became his lover, Meliodas calling her his "most important person to him." He has stated that he tried to protect Danafor and Liz, but failed, and that this is his sin, as a member of the Deadly Sins.

However, on the contrary, Meliodas is said to have destroyed Danafor himself after having lost himself in his wrath. According to what Veronica has been told, Meliodas' true identity is that of a "raging monster that leaves a path of destruction wherever he goes," with his childlike appearance being but a facade.

16 years ago
When the Deadly Sins were not yet formed, Meliodas found Diane being bothered by a group of knights called the Knights of the Golden Wheats where the latter went in and knocked one out. Both the knights and Diane told Meliodas to leave, and the knights also said that Meliodas should not help Diane since she is a monster to which Meliodas said it was wrong for them to pick on a girl and defeated them all with ease after they made racist comments. Meliodas later ask Diane if she was frightened which surprised her since she was bigger than him, but fell in love with him due to his kindness and treating her like she was a normal person.

Meliodas, intending to recruit Ban, arrived at the convict's cell, where he was warned by the guards of Ban's immortality. Ban, believing that another execution was to be performed, stated that he will merely sit as he is executed, only to find that a child had entered. Ban refused to join Meliodas, and, to Meliodas' declaration that he will then take him out by force, engages him in battle. Their battle is revealed to have resulted in Ban being punched out of his cell. Ban, having become extremely excited, requests that the battle be continued. Meliodas responds that in order to do so, Ban would have to join him, with Ban merely continuing to grin widely.

After the formation of the Seven Deadly Sins, Meliodas and his team participated various missions; a notable one being defending the Maiden Castle of Edinburg from a group of vampires. At one point of time, the Sins were resting after defeating a Tyrant Dragon when Ban took an interest in Meliodas' broken blade and attempted to steal it, only for the latter to use his mysterious Enchantment: Hellblaze to give Ban a scar that can never heal despite his regenerating abilities. Later, Meliodas met Dreyfus and Hendriksen while eating after training with his fellow Sins and commented that their superior, Zaratras, is invincible, only for Hendriksen to claim that he is being modest. Meliodas complimented Dreyfus' sword skill, which made the latter happy and begin to respect the captain of the Seven Deadly Sins.

10 years ago
Before they infamous frame, Meliodas was training Gilthunder until Gilthunder grew upset as he believe he will never become as strong as the Deadly Sins or his father, but Meliodas told him to ditch his negative attitude and Margaret came, and told him the The Way of the Knight creed. Margaret told Gilthunder that he should be himself, and not like the Deadly Sins or his father, and she believes that Gilthunder will be the kindest and strongest Holy Knight some day which cheers up Gilthunder. However, the next day Gilthunder came running toward Meliodas and told him to run away with the others. Meliodas was lost at Gilthunder and told him to explain everything, but Gilthunder told him something terrible is coming and if he told somebody, bad things will happen, and Gilthunder has no idea what to do. Meliodas told Gilthunder to calm down by hitting his head and told him what he want to do, which Gilthunder said that he need to protect Margaret, but has no idea how to do it. Meliodas teach him a charm which could cheer him up whenever he feels sad or terrible which was to say out loud that he was stronger than any of the Seven Deadly Sins. Gilthunder said it, which Meliodas points out that he should feel better soon. Meliodas embrace Gilthunder, told him he shouldn't cry, and if he is in trouble, he will come to his aid.

When they were still an active and commended group of knights, they supposedly summoned to an old castle after defeating the troll queen and destroying the Great Druid Altar. As the Sins were inside the castle, they discuss among themselves of the reason behind the order they received as Meliodas complained that they should be attending Liones' National Foundation Day Festival and go drinking only for King to remind his captain that he is always drinking anyway. After Diane and Merlin speculate whether their superior might reward or scold them in their last mission, Meliodas already decided that it is a scolding and reminds his team to attend the festival later much to his team's chagrin. As they enter the room, they discovered the Great Holy Knight, Zaratras completely skewered to death. Soon, they were framed for the murder, and then, surrounded by over three hundreds knights of the kingdom. As the Liones' Holy Knights attacked the castle, Meliodas gave his last orders to his team to disperse and regroup later to figure out the cause of Zaratras' death to which everyone complied and separated while fighting their way out. In the aftermath, Meliodas claims to not remember anything that happened afterwards, except that one of the Seven Deadly Sins apologized to him, which leads him to suspect the existence of a traitor.

Once Meliodas awake, he came to meet Hawk within a cave that is close by to Camelot as the two end up speaking with one another, where Hawk mention that he felt like he used to fly in the sky, thinking he was a Dragon back in his past life when Meliodas thought he was Wandle. The two argued over Hawk name, until Hawk mention of a restaurant named Pig Leg where Hawk loved the leftover there which led Meliodas and Hawk to team up and worked together since Meliodas can't work as a knight anymore due to an incident in Liones, but decided to open an bar named Boar Hat after the restaurant Hawk mention by selling his Sacred Treasure which he felt bad about Bartra as he give him his weapon and build it on Hawk's Mother back. Since then, Hawk and Meliodas became partners in business as Meliodas is the owner while Hawk is the cleaner as he could eat the leftovers.

Introduction arc
Meliodas is first seen in the Boar Hat, serving his disgusting meals, and then ordering Hawk, a talking pig, to clean up the vomit of his customers. Moments later, the infamous Rust Knight enters the bar, scaring all the customers who believed him to be one of the "Seven Deadly Sins", and collapses moments later, which reveals him to be female. The woman soon wakes, is then offered food and questioned as to what she was doing in an armor. As she begins explaining that she is searching for the "Seven Deadly Sins", a few knights, having been informed by the villagers of the Rust Knight, demand that Meliodas and him come out. The young man and Hawk do so quickly, and anger one of the knights by the latter's pretending to be the Holy Knight. As the woman when flees towards the woods, they notice her, and go in her chase. She is quickly rescued by Hawk and Meliodas, who ask for her to continue her answer. She then explains that she was searching for the "Seven Deadly Sins" in order to stop the Holy Knights, who, few days ago, had orchestrated a coup d'etat, and had taken control of the kingdom; she also reveals who the Seven Deadly Sins are.

Abruptly, the cliff the three are standing on, is cut off by Twigo. Meliodas, however, rescues all of them. After he does so, Twigo notices the woman's earring, and then realizes her true identity as Elizabeth, the third princess kingdom. When the knight attacks them, Meliodas rescues her; he does so again when she gives up her life in an attempt to not involve Meliodas in her matters. Smiling, Meliodas reveals his name, and thus, his identity. As Twigo attacks them again, Meliodas repels the attack, and, declaring his title as the "Sin of Wrath", then again repels Twigo's attack with his broken sword, thus defeating him. Meliodas, explaining that he is also searching for the other Deadly Sins, offers Elizabeth to accompany him in his journey, an offer she tearfully accepts.

Hired as a waitress of the Boar Hat, Elizabeth is given a new set of attire by Meliodas. She then questions him as to the crime had had committed, and doubts whether he is an actual criminal. He initially jokes about the reason, but, in the end, he doesn't properly answer her. Meliodas, Elizabeth and Hawk soon reach Bernia, a village famous for its ale made from the village's famous river; they, however, they find the river to be completely dried. Upon finding a large crowd of men trying to pull out a sword, the three discover that the previous day, a Holy Knight had sealed the river's underground water supply, preventing the creation of Bernia ale, the the town's primary sources of income. While the men unsuccessfully try to pull out the sword, a boy named Mead starts boasting about his friend from the Seven Deadly Sins, his comments only serving to further enrage the villagers, who begin blaming Mead for their crisis.

Meliodas takes Mead to Boar Hat and feeds him in return for information on his "friend" from the Seven Deadly Sins. This, however, turns out to be a hoax. Elizabeth, having learned that Mead was the one who angered the Holy Knight, manages to have him tell her the reason he did so, by narrating him an episode of her childhood. The four then watch from the window as two knights inform the villagers that if the sword is not removed by that day, taxes will be multiplied by ten times. As all the men, now including Mead, try their best to remove the sword, Meliodas, after drinking some of the Bernia ale, removes the sword with ease, in order to pay for his drink, which causes the dammed water to gush up like a fountain.

Some time later, Meliodas asks Hawk and Elizabeth to buy some herbs and fruits with the silver coins he hands them, for Elizabeth to gain some experience, since she, being a princess, has never seen a silver coin before, having used only gold ones. He also informs them that the day's main dish will be the Dusk Bison that has been acting as a pest and destroying people's farms. When the two return empty handed, and explain how they lost the items they bought, Meliodas hilariously expresses his irritation.

That evening, as the villagers celebrate in Boar Hat, Meliodas instructs Elizabeth to take her job lightly, since it was her first time being a waitress. During the celebration, Meliodas senses Gilthunder's, the aforementioned Holy Knight, spear heading for the village, and goes out. Outside, he finds Elizabeth, who, having made many mistakes while waitressing, had run outside while crying. Encouraging Elizabeth, Meliodas stops the spear, but only after being pushed back a large distance. He then sends it back at Gilthunder, which leads to the destruction of Fort Solgales, and the Holy Knight's realization that the Seven Deadly Sins are still alive. The next morning, Meliodas suggests that they should leave the village immediately and continue their journey, since it would be more dangerous for the villagers if they stay there.

Forest of White Dreams arc
Having learned of even Holy Knights avoiding the Forest of White Dreams in Bernia, the group of three travel there, speculating of a Deadly Sin hiding inside. After walking in the forest for more than three hours, and losing their sense of direction, the three find multiple copies of Hawk, all claiming to be the real one. Meliodas, mercilessly defeats all the copies, including the real one, but then discovers similar copies of Elizabeth. Each of them declares to do anything that they are real, and Meliodas then instructs them to jump as high as they could. All of them, except the real one, do so, since Elizabeth's panties had been stolen by Meliodas before, and she was embarrassed to jump. Defeated, the copies show themselves as Prankster Imps, and retreat towards a giant girl, who is revealed to be Diane, the Serpent's Sin of Envy. They then apologize to her for allowing a Holy Knight to come through, having believed Meliodas to be one.

Immediately after being woken, Diane lifts Meliodas with her hand, only to cuddle him and cry tears of joy as soon as she realizes his identity. When Elizabeth introduces herself to Diane as traveling with Meliodas, Diane jumps to the conclusion that she and Meliodas are a couple, and throws a tantrum. Meliodas, after calming her down, explains to her the reason he and Elizabeth were traveling together. He then proceeds to begin a discussion about the day, ten years ago, informing her that he has almost no memories of the day, much to Diane surprise. Meliodas narrates the only memories he has, which end with one of the Deadly Sins apologizing to him. The narration leads Elizabeth to speculate the existence of a traitor, and Diane, to declare that she will help Meliodas. Few brief moments later, Hawk notices a gigantic thundercloud in the sky. A lightning bolt from it then binds all of them and the assailant is shown to be Gilthunder.

As Gilthunder walks towards them, Elizabeth explains Gilthunder's identity, and that he was a brother figure to her, but soon realizes his intentions. After Gilthunder leads her away, ending her interruption, he, pointing his sword at Meliodas' neck, expresses his desire to avenge his father, and also to prove that he has surpassed him. Meliodas and Diane easily break Gilthunder's immobilization spell themselves, with Meliodas instructing Diane not to interfere. Gilthunder attacks first with a lighting bolt; the Sin of Wrath repels the spell, only for the Holy knight to dodge and move behind the latter, slashing him from behind and causing him to fall to the ground. Meliodas, seemingly in his last moments, asks for the whereabouts of the other Deadly Sins as his last words. Gilthunder answers to him the locations of the Fox's Sin of Greed, and the Grizzly's Sin of Sloth, the former being imprisoned in the Baste Dungeon, and the latter having perished in the Capital of the Dead. As he is told so, Meliodas quickly jumps back up, revealing that he had tricked Gilthunder into revealing the information.

The Holy Knight refuses stop their battle, repeatedly attacks Meliodas very quickly. He continues his attacks, but is suddenly lifted by Diane with a hand. Gilthunder's attempts of escaping her grasp unsuccessful, Meliodas watches as Diane flings him out of the forest. Meliodas later decides to head toward the Baste Dungeon, leading Elizabeth to object his decision, citing his grave wound as an impediment. Though assuring her that he is alright, Meliodas soon collapses.

Baste Dungeon arc
Meliodas is taken to Dalmary, a town near the Baste Dungeon, where he is treated by Dana. Later, Dana has Meliodas drink a medicine he prepared himself, which is later revealed to have been a deadly poison, with Dana being revealed to have made a deal with Golgius. When the Holy Knight appears, and then tries to grab Meliodas broken sword, Meliodas, however, is shown to still be alive, but with his eyes being mysteriously colored black, and with a strange black colored symbol on his forehead. As Golgius tries to pull the sword, Meliodas declares that he would not let go of it even if he dies, and that this was the only way he could atone for his sins, while releasing an aura which frightens Golgius into fleeing.

Meliodas seems to have returned to normalcy soon after this. When Elizabeth then questions him as to his wound, it is revealed to have already healed, something that puzzles even him. The three then go in Golgius' chase, soon finding him due to Hawk's sense of smell. Much to their surprise, Golgius immediately surrenders; Meliodas, however, notices the blades that Golgius discreetly threw, and blocks them. Soon after, Dana also finds Golgius, and is killed in order to censor the two's deal, with Elizabeth, worried, running towards the doctor. As Golgius disappears after his attack is blocked by Meliodas, he confirms that his ability is teleportation. The three then escape, and soon enter an abandoned building, where Meliodas slashes his sword in the air toward the door, comically claiming that it was a magic spell. They wait inside, when Golgius suddenly appears behind Meliodas, but falls for the Sin's trap - a cut on the floor of the entrance - and falls down to the bottom of the building. There, the Deadly Sin reveals that Golgius' ability is actually transparency, and how he discovered so. He then attacks his opponent at point blank range.

Meliodas then questions Golgius about the person who had ordered him to bring the broken sword and Elizabeth, only for Golgius to escape due to a distraction. After he leaves, Elizabeth goes towards the dying Dana, who apologizes, explaining that he had only wanted to rescue his daughter and, lamenting his inability, dies. Elizabeth blames herself for this, since if she had not found Meliodas, he would not have been put into danger, and Dana would not have died. Meliodas, in response, questions whether her resolve to protect the kingdom's citizens was as weak, declaring that he would fulfill his promise even if she were to die. He proceeds to speech her on the inheritance of the principles of an individual. Not long after, him and Hawk start for Baste, leaving Elizabeth in Dalmary due to the dangers. She, however, joins the two herself and, encouraged by Meliodas' speech, responds that though she has no power, she will continue to fight for the people even if he were to die. As they walk, they encounter Diane, who seems to have no memories of defeating Friesia's insects and leaving for Baste.

Diane tries to recollect the events, and Meliodas then determines rescuing as Cenette was their main priority. Suddenly, he finds Diane to be attacking him; immediately realizing that she is under an illusion, he flees along with Elizabeth and Hawk, and, upon finding two civilians, walking nearby, takes them along. As the three, and the two frightened civilians, hide, Meliodas also falls under Ruin's hypnosis when he tries to look at Diane, which makes him see Ruin in her place the same way she sees Ruin in his. Thinking he is attacking Ruin, he attacks Diane, which begins their battle. The battle is only stopped after Elizabeth manages to remove the origin of Ruin's illusion - the bell on his staff. He, enraged by this, charges towards the heavily injured Elizabeth, but is stopped by Meliodas, the illusion now having stopped.

Meliodas tells the unconscious Elizabeth that he accepts her resolution, as Ruin attacks him. Ruin expresses his disbelief at the kingdom being frightened of a "small child". After two of Meliodas' punches, Ruin, exclaims that his soft fist would not even scratch his armor, and suggests that he draw his sword. When Meliodas does not, Ruin attacks with a barrage of punches; though they possess great power, Meliodas remains unscathed, and breaks Ruin's armor. He is unfazed when Ruin then hardens his abdominal muscles as his armor, and proceeds to easily defeat him with a punch that plunges his arm into the Holy Knight's stomach. Later, when Diane, Meliodas, Hawk and Elizabeth, who is sleeping inside Diane's bag, enter the dungeon, they encounter Cenette fleeing from Ban, as him appears soon behind her. Initially appearing very tense despite their reunion after 10 years, Ban and Meliodas are shown to get along very well, and greet each other with multiple high-fives at great speed. They then energetically start arm wrestling, the mere force of which begins destroying Baste. Both argue on their score on arm wrestling as the dungeon continues collapses. After it is fully destroyed, Ban states that he is glad to meet Meliodas again.

The group, Ban, and the people who were imprisoned in Baste, including Cenette, return to Dalmary. Soon after, Meliodas enters Dana's house, but is surprised to discover that Dana is mysteriously alive. The doctor reveals that he knows nothing about this strange phenomenon, and showing the deep wound to have neatly healed, points out that it was similar to Meliodas' sword wound, which had also healed and left a scar in a similar way. Cenette then interrupts, questioning the reason her father was nearly killed and she, imprisoned. When he answers, she tells him that poisoning Meliodas was not his fault, but the Deadly Sins' own fault, since the group were criminals. Dana, however, argues against, explaining that Meliodas never blamed him, and even selflessly rescued her. He then offers a token of his gratitude by a meal. At night, during the party, Ban is formally introduced to the bedridden Elizabeth. Not long after, Cenette notices crossing shooting starts in the sky and brings them to everyone's attention.

Capital of the Dead arc
The characters begin their journey towards the Capital of the Dead from Dalmary Town. Meliodas decides to not head towards the Kingdom's capital yet, but instead, they move further away. On the road, they are confronted by two Holy Knight apprentices, with one know as Andre. Meliodas initially deceives them by advertising their Boar Hat bar with Diane and Elizabeth being the two attractive waitresses. However, after Diane released her appreciations of being praised by hugging him, the knights realize that they are the Seven Deadly Sins. Suddenly, a Black Hound appears and quickly defeats the two knights. When Ban attempts to scare the creature, it grew bigger as a result of feeling threatened. In the end, Meliodas intimidates the Black Hound with his Broken Blade's powers.

Gradually, the characters arrive at a lonely village that is said to be closet to the Capital of the Dead. Meliodas decides to open the Boar Hat bar in order to earn some money for food, and begin giving everyone roles. When Ban begins complaining about working, he reveals that he return Cenette her dagger, so they could not sell it for money. When everyone was about to begin working, they discover that Ban had escaped. At the Boar Hat, Meliodas tells a past story about Ban and King and states that they are a unlikely dynamic duo.

Meliodas and the rest begin searching for Ban, and discovers his fighting against King. He suddenly appears and interrupts the battle by knocking Ban on the head with a cup. Meliodas and Diane then easily notices King, although he quickly runs away. Back at the Boar Hat, Ban cooks a delicious meal and requests for the location of the Capital of the Dead from Ellen and her brother, who reveals that King has also requested the same thing.

The discussion about the Capital of the Dead continues and the characters are told that the village is actually the entrance. However, you cannot go there just because you desire to. Out of the blue, Ellen recites a riddle she always heard from her neighbor, a priceless memory shared with the deceased will open the path to the capital. The characters then begin searching for a method to enter the Capital of the Dead. Realizing that there are flowers on the ground, Hawk begins sniffing them when a sudden breeze wafted all of the petals. When the characters opens their eyes, they discover that they arrived at the Capital of the Dead.

Ban suddenly runs away, leading Meliodas and the rest to follow after him. Whilst attempting to follow, they is blown away by an explosive strike from and Guila, but easily recovers. He then suddenly encounter the Holy Knight Guila who killed herself to enter the Capital of the Dead. She begins attacking when Meliodas immediately tells Hawk to run away with Elizabeth after realizing how dangerous she was. Meliodas catches Diane who was also blown away the same way. The two then begins attacking the Holy Knight together, before Guila provokes Meliodas to use his sword. In response, Meliodas draws his broken blade and utilizes Full Counter against Guila, who reveals that she knows the ability.

Meliodas and Diane were still fighting Guila but she was too strong and Guila was about to use her power she called Explosion but she was stopped by Ban using his power Snatch but Guila used her Explosion to broke Ban ability. As the battle continues, the Sins were losing but then King arrive and offers to help them. Guila used her power again to kill the Sins but King block that attack and decided to fight her alone which the other Sins agree to and sit down and watch the fight.

Meliodas and the other watch as King defeated Guila with ease but then she came out of the rubble and was about to attack King but Meliodas block the attack and sent her back to the living world. The Sins bodies were starting to disappearing and are about to go back to the living world. When they are back they saw that Guila was there but still in a near death state and had not returned. Ban said that they should kill her but Meliodas had an idea to do something to her. The Sins later left the village to continued they journey. King ask Meliodas who Elizabeth is but as always he tease her but then told him she is the princess which surprised King and decided to go to his fat form to show respect to Elizabeth but Meliodas does not notice the differences but the clothes. When King asks what happen to his Sacred Treasure, which Meliodas says that he sold it.

Byzel Fight Festival arc
Not long after, Meliodas questions King the current status of the kingdom. Later, at night, inside the Boar Hat, Elizabeth somberly remembers her childhood; her spirits are lifted with Meliodas reassuring her that her family will be rescued soon. The next day, he decides their next destination to be Biron, and then questions King about his statements the previous day. King, in response, reveals Guila was a mere low rank apprentice the day before she fought them, explains about the mysterious "New Generation". Meliodas, and three others, then enter Biron, where they also discover a new wanted poster for Elizabeth. All the residents unsuccessfully try to chase the criminals in order to hand them to the Holy Knights. After the four escape to a tower, Meliodas and King leave Elizabeth and Hawk to gather information, upon the princess' own urging.

In the evening, Hawk tearfully explains to Meliodas and King about Elizabeth's capture by Griamor and Veronica. Though King suggests to formulate a plan, Meliodas, enraged, states that they are going then. King, upon finding the inn where Elizabeth is being held, uses his telekinetic abilities to topple a cup on the table. While Griamor reaches out for it, creating a distraction, Meliodas enters the room, and very quickly defeats Griamor in an ambush. Later, Elizabeth thanks Meliodas, and, as the two walk, Meliodas' shadow is shown as the silhouette of a giant monster. The next day, near the town of Byzel, Meliodas explains about the town hosting an annual flea market, and about his speculations of a sacred treasure being sold there. Meliodas, Ban, King and Hawk head to the town, and there, are directed, by an alcoholic, elderly man, to the Fight Festival, whose rewards include Gideon, Diane's sacred treasure. Sometime later, after a brief skirmish with Taizoo, Meliodas, Ban, and the unwitting King, along with the other contestants, gather at the fighting ring for the preliminary round.

During the preliminary, Meliodas is among the handful of combatants who overwhelm the rest, and later qualify for the main tournaments. Afterwards, Meliodas is assigned to battle Ban in the first round. Ban had entered himself, Meliodas and King as "Baan", "Meliodaz", and "Old Fart", respectively. Hauser almost recognizes the two, but dismisses them as the Deadly Sins because of their obvious aliases, due to his naivety. When the first battle between Matrona and Griamor begins, Meliodas, along with others, ponders whether the former is Elizabeth, when she reveals her identicalness to the princess. After Matrona wins, her hat falls down, revealing her facial identicalness to Diane's. She skips toward the three Sins, but is only greeted with Meliodas's question as to her identity, which angers her and prompts her to punch him and storm off. She then answers to King's questions, explaining how she and Elizabeth were shrunk.

Diane merrily states that she had wanted to surprise Meliodas, and jumps on him, expressing her elation at being held by him. She then asks Meliodas to grope her, as how he often gropes Elizabeth. When she becomes upset at his refusals, Meliodas comforts her, explaining that he cannot act so to an important individual as her. After King and Cain's battle, Meliodas and Ban ready themselves for their battle, which is the final one in the First Round. As the battle begins, Meliodas compares the circumstances they are in currently to his and Ban's first meeting, and punches him. Regaining his balance, Ban exchanges several attacks with his opponent. One of Meliodas' punches sends Ban crashing onto the ring, even breaking the Great Byzel Rock. Soon, when Meliodas attacks Ban again, he himself falls down to his knees, Ban having used his ability, "Snatch".

When Meliodas tries to retaliate, he seems to have weakened. King explains that this is since Snatch enables Ban to "rob" physical objects and also physical abilities such as speed and stamina; Meliodas is losing his stamina. As Ban overwhelms Meliodas, he then also starts "robbing" Meliodas' raw strength. After sometime, Ban decides to now rob all of Meliodas' abilities together, as otherwise he would not be able to end the battle. While Meliodas attacks Ban, the latter steals the former's abilities, and manages to completely do so before he is defeated. As he stands over Meliodas, Ban allows him to give up, an offer Meliodas immediately refuses. Diane theorizes that Meliodas is baiting Ban into delivering the punch, and will reflect the blow back with Full Counter. King quickly refutes this, explaining that Full Counter can only reflect "power" attacks, and not indirect attacks like Ban's.

Despite Elizabeth's pleading, Ban punches Meliodas. In the midst of the resulting debris, Meliodas, who now mysteriously has a strange black colored mark on his forehead, and with his eyes colored black, similar to how he was when Golgius had attacked him previously, crushes Ban's hand, and proceeds to defeat him. After Diane's battle against Hauser is announced, Diane hurriedly hands Meliodas a shrunken Elizabeth, before leaving for the battle; the Sin of Wrath smirks perversely at the sight of a shrunken and naked Elizabeth. While Diane enters the fighting ring, Meliodas teases Elizabeth. The princess then tries to question Meliodas as to why he acts pervertedly towards her, believing that this is since he does not consider her to be important; this is why she has been dejected for a while. He, however, does not hear her response, leading her to dismiss it, and mentally resolve to believe in him. She then proceeds to then having him promise her that he will not battle recklessly, as he did with Ban; Meliodas, however, mentally adds that he will only do so when she is nearby, hilariously.

After Diane's battle, Cain and Meliodas enter the ring for their battle. After a brief conversation on whether Cain entering the Fight Festival was a coincidence, Cain, questions him whether he is Meliodas' son, and is greatly surprised upon learning that his opponent is Meliodas himself. Initially disbelieving, Cain, after accepting the fact, attacks Meliodas, and jumps back, declaring that he cannot forgive Meliodas, who betrayed the kingdom, its people, and his most important person. Meliodas then recognizes the symbol on Cain's shirt as Danafor's crest. Questioning Meliodas as to why he destroyed the kingdom, and killed its citizens and Liz, Cain attacks him with a fireball; Meliodas does not evade them. Cain, finally ending his attacks, releases a giant fireball. Meliodas, answering the series of questions, states that he had tried to protect Danafor, but failed, and that this failure is his sin. Facing his palm towards the attack, Meliodas completely disperses the attack. Cain recognizes this technique as "Counter Vanish", the use of which having convinced Cain of Meliodas' identity.

Meliodas replies that he has come to remember Cain as well, and reaffirms Cain of his earlier statement. Cain, delighted that the rumors about Meliodas' responsibility for the destruction of Danafor are false, and glad to be rid of suspicions, forfeits his match. Finally, for the final battle in the tournament between Meliodas and Diane, or Matrona, both fighters enter the ring. Diane suggests to end their battle soon, since they have already won their target: Gideon. However, they are then interrupted by three women, who cheer Meliodas in a very erotic manner. Diane, enraged at Meliodas' obliviousness on this, punches him as their battle begins; Ban had paid the three women to cheer erotically for Meliodas to anger Diane, and have her battle Meliodas seriously. Meliodas realizes Ban's scheme and exchanges a barrage of powerful attacks when Diane when she refuses to believe that she has misunderstood, with one of the attacks nearly pushing him out of the ring. Regaining his balance, Meliodas then jumps, and tries to attack from above.

Diane, however, stops the punch, and sending him flying, all the while slowly returning to her usual size. As Diane grows, Meliodas escapes all of Diane's repeated punches by slipping through the cracks their battle has created on the ring. As they battle, the audience expresses its disapproval and dislike at the low seriousness of the battle. In response, Meliodas stops fighting, and declares his identity as a Deadly Sin, and also that the Sins will be capturing Byzel. After King and Ban also enter the ring, Meliodas continues, threatening the civilians to leave Byzel in one minute, lest me massacred. A few moments afterwards, gigantic, and explosive flares rain down on Byzel. As the assailants, Guila, Jericho, and another Holy Knight, land, the citizens are intimidated by Ban into fleeing, which makes Elizabeth realize the motive of the Sins' actions: they had forced the civilians to leave, so that they would not be involved in the battle against the Holy Knights. Meliodas, noting on the Holy Knights' strength, instructs King, Diane and Ban to separate.

Soon afterward, Guila finds Meliodas. He accepts to fight her, but she retorts, boasting her increased abilities, and then releases several flares, which stop midway. When he jumps to destroy the flares, one of them suddenly explodes, which triggers multiple explosions. After the gigantic inferno settles, Meliodas, heavily injured, falls from a height. After Jericho also defeats Ban, King confronts the two Holy Knights, and defeats them with great ease; he then hands Elizabeth and Hawk the responsibility of watching over the two defeated Sins. Hiding behind a building, Elizabeth hangs the pendant that Veronica gave her earlier around the unconscious Meliodas' neck, as Veronica and Griamor find her and Hawk. Veronica notices the pendant on Meliodas' neck, and then grabs Elizabeth's hand, trying to bring Elizabeth back to to the capital of Liones. As Elizabeth tries to resist, Meliodas regains consciousness and stops Veronica, trying to convince her that he will protect Elizabeth.

Angered further, Veronica triggers the Goddess Amber, the stone on her pendant that affects demonic beings. The stone shines brightly for a moment, and Meliodas then disappears. Annoyed at Elizabeth still refusing to return with her, Veronica finally orders Griamor to use force. Ban's attempts at opposing them are stopped by Jericho and Guila's arrival. While Veronica and Griamor are focused on Guila, Elizabeth manages to flee, with Veronica chasing behind; the princesses' footsteps trigger one of the explosive mines Guila had set previously, leading to Veronica's death. Guila then reveals Hendriksen's goal: the resurrection of the Demon Clan, and tries to bring Elizabeth back with her. As the princess pleads for Meliodas to rescue her, the Goddess Amber darkens, and shatters, releasing a black substance, which collects and forms Meliodas, the right portion of whose body is completely colored black from forehead to knee, with spiral-like designs. Noticing Guila holding his broken sword, Meliodas sewers, and grabs Guila's hand before she is able to notice; he holds her hand, which is, in turn, holding his sword.

As Guila screams in pain, Meliodas returns her amputated hand and lightly swings his sword to deliver a blow which knocks both Guila and Jericho away. Jericho immediately proceeds to utilize an Incantation Orb to heal Guila, when Meliodas continues to proceed attacking them. Losing conscious, he ends up slicing Ban in half as well as completely destroying the nearby terrain. He notices a worried Elizabeth and begins inspecting her through smell, causing her to gradually become confused. Acknowledging that she is not an enemy, Meliodas manipulates that black substance around his body to form a wing around his right arm, then heading off towards where King and Helbram was located. He interrupts the battle, knocking King away as he lands, and subsequently begins attacking Helbram. Preventing the Holy Knight commenting, Meliodas begins executing a succession of attacks, appearing to have gain the upper hand, when Helbram returns with a heavy blow. Helbram takes the opportunity and questions whether Meliodas was mixed from the start, as he appears to be fundamentally different from Guila and Jericho.

Appearing to be unable to comprehend what Helbram is asking, Meliodas continues the battle by manipulating the black substance again, but forming a gigantic blade instead, to send a series of slashes with aggressive killing intent. The Holy Knight deflects the strikes with ease, quickly moving behind Meliodas and attacking, thinking that his blow had accidentally split the Deadly Sin into two. Meliodas protects himself with the black substance acting as an armor and negating all the damage. He forms a wing again, attempting to reduce the distance between him and Helbram, when the latter uses the ability Hunter Wisp to create homing blast attacks, realizing that Meliodas has lost his Full Counter ability after they hit. Cornered, he molds two claws with the black substance and continues his attacks, only to be stopped Helbram who reveals his ability Link and stabs Meliodas with his sword.

Despite being told that Helbram possesses the powers of 20 more Holy Knights, Meliodas adjusts his posture and launches towards him, delivering consecutive bashes with the large claws. The 20 Holy Knights supporting Helbram via the ability Link are astonished that he was been overpowered, realizing that Meliodas' powers may still be increasing. Suddenly, Hendriksen appears before the gathering of the knights, lending Helbram a fraction of his powers, who consequently sends the rampaging Meliodas crashing into a wall with a single blow.

While knock out, Meliodas was then saved by Diane with her scared treasure Gideon and end up defeating Helbram, but as well destroyed Byzel. When Meliodas woke up, Diane cuddle him in happiness. Later, Elizabeth ran happily to the saved Meliodas, but Meliodas was then punch by Ban due to being cut in half by Meliodas. Elizabeth then walk to the wounded Meliodas and hugged him for being alright, Meliodas was happy and told Elizabeth that she need some underwear while grabbing her butt, leaving Elizabeth embarrassed and a upset Diane. Meliodas was then told by Ban of his sword fate which surprised Elizabeth and King of the missing sword, but Meliodas stated it was stolen and acting care free which surprised Hawk. Elizabeth told Meliodas that sword was something important to him and said if it was really fine, to which Meliodas stated it is not fine, and it is a dire situation which surprised Elizabeth, but then Meliodas stated that if Elizabeth is alright, then loosing the sword was not a big deal which made Elizabeth blush heavy and made Diane upset for not worrying over her instead to which Meliodas state that she is always fine.

Meliodas and the rest, treating each other wounds and headed to the next location to find another Deadly Sins member or the sacred treasure.

Kingdom Infiltration arc
While traveling on the road, Meliodas group ask him of what the next Deadly Sins to find to which the latter that their are heading to Kingdom of Liones to get his Broken Sword back but the Deadly Sins refuse due to his fault of losing it.

Then a Holy Knight brute with heavy melee gauntlets end up in their way trying to face them which Meliodas immediately knocked him out with a powerful punch and continued.

The Deadly Sins then stopped when they felt a large power coming from the south of the kingdom which turns out to be Camelot army with their leader Arthur. Later, the trio continued to cut through the Holy Knights as they attempted to break through. Deciding to end this with minimal bloodshed, Gowther used his Sacred Treasure Herritt to overwrite the memories of the attacking Holy Knights and turned them into allies. Gowther explained his technique to the bewildered Meliodas and Ban who then told him not to use that on them no matter what which Gowther complied. The trio sneak away from the Holy Knights and went into hiding to find out a plan. Ban told Meliodas that they should head to the Liones castle because in fairy tale, the princess always get lock in underground prison. Meliodas agreed to the plan and head out to the castle as Meliodas promise to save Elizabeth. The trio then sense a battle going on to the south gate which Meliodas decided to head over there, thinking Elizabeth could be there.

When Dreyfus announced the citizens of the Sins' presence, Meliodas keeps running while Ban called the Great Holy Knight a bastard. As Dreyfus was under Gowther's Nightmare Teller, a past version of Meliodas appeared having a meal after training with his fellow Sins. He comments on his superior's skills and called Zaratras invincible only for the younger version of Hendriksen to claim that Meliodas is being modest. He then compliments Dreyfus' sword skill and tells him that he lacks the skill and ambition to surpass his brother while munching on a handful of mini-Hawks. Meliodas disappears after telling Dreyfus that it is already too late and asked the skewered corpse of Zaratras if he is right, thus beginning the nightmare on the Great Holy Knight. Meliodas and Ban stopped at their track when they saw giant roots attacking a small town where Diane, Gowther and King are located. Ban ask Meliodas if he could sense it, which Meliodas nodded as he mention that Diane's and Gowther's powers are fading, but King's ability is raised to invincible level.

Meliodas later saved Arthur's life when Hendriksen used Hellblaze on the king of Camelot and Meliodas used Full Counter to reflect the attack back at Hendriksen much to his shock and Meliodas saying that Hendriksen learned a very dangerous ability while he was gone and told him that he is going to get Elizabeth back. As Meliodas stepped forward and faced Hendriksen, he asked him about the location of Elizabeth, but Hendriksen refused to tell him. Meliodas immediately tried to kick him in the face, but Hendriksen was able to block. Meliodas followed with quick slash attacks, but his opponent was able to dodge them with ease. Hendriksen then tried an attack, which Meliodas blocked, but was send back. Moments later, Gilthunder came down from a thunder cloud attacking Meliodas, who was able to parry his attack. Both exchanged multiple attacks, and both blocking each one of them, but eventually Gilthunder was able to kick Meliodas in the chest and send him back, were he was caught by Arthur. Meliodas thanked him and asked him if he can give him a hand in the fight. He also asked him for his name, as Arthur told his to him, he also mentioned he have heard of him and know him and then they both prepared to face Gilthunder and Hendriksen together.

As Meliodas and Arthur were prepare for their battle against Gilthunder and Hendriksen, Hendriksen notice that the battle from the other side was over and believed that Dreyfus had won the battle, while Meliodas believed that none of his members would loose so easily either. Hendriksen points out that Meliodas came rushing in to the enemy stronghold with a few member of his teams and without any plan. Hendriksen point out that the Deadly Sins were nothing, but a former shadow of themselves and that saving Elizabeth is futile. Meliodas however, rush in with great speed and attack both Hendriksen and Gilthunder at the same time and said that even if he give up on his life, he will protect Elizabeth. Meliodas end up fighting against Gilthunder while Arthur was amazed at their skills despite not fighting seriously, but still end up fighting against Hendriksen.

As the Meliodas fight was proceeding, he was able to push Gilthunder back, but then he used an attack summoning lighting-beast-like attack from the thunder clouds. Meliodas used his Full Counter to reflect the attack, but understood it that this was time delayed attack and had to reflect the other 2 incoming attacks as well. In that moment Gilthunder got behind him and slashed him, but Meliodas was able to block using the sheath of his sword, Gilthunder immediately went in front of him and with an a attack was able to knock Meliodas' sword from his hand. Gilthunder then used an large lighting attack on Meliodas, but using the unknown dark power, Meliodas with just his fingers was able to stop Gilthunder's attack easily. Once Meliodas stop Gilthunder attack, he regain his sword back and went on with the fight, without the Black Mark. Meliodas and Gilthunder battle rage on and shows that both of them are equality match. Gilthunder sent Meliodas flying to a building, but Meliodas stop the crash by putting his feet inside the building.

Meliodas ask Gilthunder if he really want to have a death match with him, which Gilthunder respond by using Meliodas old creed of The Way Of The Knight which the creed goes "your eyes are to discern evil, your mouth to speak the truth, your heart is filled with righteousness, and your sword is to purge evil" but Gilthunder now believe that the Deadly Sins have turn down that creed and betrayed the kingdom. Gilthunder claim that he is stronger than any Deadly Sins, but Meliodas just nodded and continued on their fight with full speed. Later on, Meliodas started to overpower Gilthunder, while the latter try to fight back with all his strength, but with no luck. Meliodas try to slice Gilthunder, but Hendriksen appear and struck Meliodas which the latter dodge in time, Meliodas was surprised to see Hendriksen and saw Arthur was defeated. Arthur apologize to Meliodas for not buying time, but Meliodas told him to rest and leave the rest to himself. Meliodas end up battling against Hendriksen and Gilthunder at the same time, while Hendriksen said that they need to take down Meliodas since he is their greatest threat. Meliodas started to nearly overpower the duo, until the unnamed Holy Knight who kidnapped Elizabeth, appear and freeze him solid with Freeze Coffin, but did not last long. Meliodas end up facing against Hendriksen, Gilthunder and Vivian.

Meliodas begin to be overwhelm by the Holy Knights trio, however, it was revealed by Hendriksen that Meliodas power is increasing instead of decreasing and the reason for Meliodas not fighting back against the trio is because Meliodas is heightening his utmost power and senses to unleash a one decisive attack. The Holy Knights used all of their power together to finish off Meliodas before he could unleash his attack. Hendriksen summon Hellblaze, Gilthunder used Sword of the Thunder Emperor, and the Masked Holy Knight use Quad-Element Destroyer as Meliodas summon his attack, Divine Slayer. However, Margaret came running toward the battlefield to stop Gilthunder from hurting his hero, Meliodas. However, Meliodas spot something close to Margaret and use his Divine Slayer to kill an invisible creature like demon that was next to her. As Meliodas grin of destroying the creature, the Masked Holy Knight attack hit Meliodas, heavily injuring him. Hendriksen rush to Meliodas to finish him off, Gilthunder appeared and cut off Hendriksen arm. Gilthunder smile and thanks Meliodas for setting him free from the spell as Meliodas smile.

As Gilthunder cut off Hendriksen arm, Hendriksen yelled out in anger for betraying him. However, Gilthunder pointed out that he was never on his side to begin with. As Hendriksen try to summon Hellblaze with his left arm, Gilthunder stop Hendriksen and sent him flying. Gilthunder ask Meliodas to leave it to him as it was waiting for this moment for a long time to have his revenge against his father's murderer. Margaret stood there, lost at the current event and the monster that was close to her. As Meliodas clean himself and walk toward Margaret, the latter ask how Meliodas knew about the monster, Meliodas explain that he realize something was off when they met in Forest of White Dreams and realize what is wrong with Margaret a few moments ago. Meliodas explain that Gilthunder would never compromise his sense of justice if hist life was in the line, and realize that Margaret was in danger the whole time. Margaret started to cry and thanks Meliodas for saving them. The Masked Holy Knight ask what made him realize the event, which Meliodas explain that the creed and the way Gilthunder said he was stronger than the Deadly Sins was some kind of code or charm if he was ever in trouble which Meliodas give him ten years ago, and when Gilthunder said those word back in the White Dream, he knew he was being watched and someone being taken hostage.

The Masked Holy Knight finds it an absurd lie, as Meliodas was fighting against Gilthunder with all of his strength, but Meliodas points out that Gilthunder put his life on the line for the woman he loves, and as such, he put his life on the line too, as he believes that it is how friendships work. Gilthunder proceed on defeating Hendriksen, and afterwards he, Margaret and Meliodas meet up with the other Deadly Sins. Upon seeing Meliodas, Diane holds him and frets over him. Meliodas ignores Diane's fretting, and tells everyone their priority is to save Elizabeth.

While the group heads to the castle to find Elizabeth and Bartra, Meliodas explains to them about Gilthunder and the Chimera that was following Margaret. Arthur shows up and compliments Meliodas' heroic deeds while the others are clueless on who is Arthur. Arthur confirms Gowther's suspicions of the mysterious power they felt earlier belonging to him at which Meliodas asks why he did not his powers. Arthur admits that he has no knowledge of his power, and wanted to fight a Great Holy Knight in order to awake his power. Meliodas and the others are dumbfounded at how Arthur decided to fight a Great Holy Knight without his powers. Meliodas and the others are suddenly teleported to a forest by Vivian, but fortunately, they are sent back to Liones by Arthur's mysterious cloaked friend. Meliodas quickly realizes that the cloaked figure must be Merlin of the Seven Deadly Sins, at which she reveals herself to the group.

Everyone was either shock or happy to see Merlin, however, Meliodas was displease as he believe Merlin was the one who knock him out ten years ago and wanted answers from her, but decided to ask her later as they need to save Elizabeth and Bartra to which Merlin happily agreed and teleport the group to the Royal Chamber. The group was shock to be in the location so fast and notice that the Dawn Roar were there as well. As Meliodas was about to destroy the door, Merlin revealed that it would be impossible to break as it was protected by Perfect Cube, as it came from the Demon World and wouldn't be destroy with either strong or weak attack. Merlin used Absolute Cancel and break the spell, freeing Elizabeth and Bartra. Elizabeth quickly embrace Meliodas as she had miss him to which the latter comfort her by touching her chest which annoyed Bartra. Meliodas point out that they have defeated Hendriksen and freed the king, and ask Dreyfus what would he do now. As Dreyfus admitted defeated and was crying to know Griamor is alive, Meliodas happily declare that everything was fixed.

After the situation, Bartra started to cough blood which alarm everyone until Merlin came and offer to heal him back in Camelot along with Arthur. As Merlin was about to leave through teleport, Arthur told her to wait as he went to Meliodas and offer him the title and rank of Great Holy Knight in Camelot as he believed that they were fated to meet. Everyone was surprised and shock at Arthur offer, but Meliodas accept Arthur offer to Elizabeth dismay as Meliodas believed that since the kingdom is saved, Elizabeth is freed, and Dawn Roar will take over the Deadly Sins job, they would be no need of him in Liones. Arthur was joy to Meliodas acceptance, but Meliodas told him not yet as he need to be in the kingdom to restore it and he still has the Boar Hat to run. Meliodas tend ask Merlin if she will rejoin the Deadly Sins who said not right away and teleport along with the sick Bartra and the depress Arthur. King then ask Meliodas if he should have question her action in the past which Meliodas blame King for. Elizabeth came and ask Meliodas if he was really planning on leaving her someday, but before he could answer, the castle was cut in half, making everyone fall down. As everyone saved each other, they witness that the New Generation are turning into hybrid Demons, including Jericho and Guila.

As Jericho transform into Demon and was about to kill Jericho and the slowly transforming Guila, Gowther and Diane appeared and stop Jericho from killing. Gowther used Invasion on Jericho and Guila to keep them calm. King seeing the situation, was about to kill Jericho to save Diane as she has few strength left. However, Meliodas stop King for a moment and told him it was strange how all of the New Generation suddenly became Demons, and realize someone has active them. Hendriksen came face to face with the Deadly Sins and the Holy Knights, explaining that he did all of this and was after Elizabeth. Hendriksen offers to spare Meliodas and the others if Elizabeth come with him, as he doesn't want to kill "one of his kind", but the group refuse to hand over Elizabeth to him, and King ambush him until he was attacked by Helbram who was revive thanks to Hendriksen forbidden technique. Hendriksen explain to King how he found Helbram and that now he is just a lifeless shell of his former self which brought the Fairy King to tears, knowing that his friend is a slave to Hendriksen. Meliodas and Gilthunder were furious at Hendriksen cruel nature and attacked him, until they realize that Vivian took Margaret and Elizabeth hostage. Hendirkcsen then stab both Meliodas and Gilthunder to the three girls shock as Vivian thought that she was going to be with Gilthunder forever, never leaving her. However, Hendriksen explain that Gilthunder will never leave her as a corpse to her shock. Elizabeth decided to go along with Hendriksen to save Meliodas life to everyone shock. Hendriksen accept her offer and was only planning to spare Meliodas, but he will spare Gilthunder as a bonus.

As Hendriksen summon a black matter wing, Elizabeth told Meliodas to think about their promise and was taken by Hendriksen to a unknown location to Meliodas dismay. Gilthunder was being heavy effected by Hendriksen ability, Acid which Meliodas said that they could either defeat Hendriksen now or dispel the spell before Gilthunder body rot. When Ban and Hawk appeared to them, Meliodas and Hawk agreed to go rescue Elizabeth and ask Ban for help. However, Ban started to attack Meliodas to the latter shock as Ban rip Meliodas arm off. During the battle, Meliodas fought Ban, but wasn't at his full power due to the Acid effect and used Demon power to reattach his arm. As Ban witness Meliodas ability, Ban ask Meliodas that if he is a part of the Demon Clan to which Meliodas didn't respond as Ban took it as a yes. As they battle, Meliodas was put against the wall and Ban revealed that the Goddess Clan promise him to revive Elaine if he killed Meliodas. Meliodas understood Ban, as he always hear him sleep talk about Elaine, and decided to accept death for Ban.

Ban was surprised at this sudden event, but decided to do as Meliodas wish, saying he will never forget about Meliodas and told Elaine to wait a bit longer. As he was about to kill Meliodas, the latter jump up and head-butt him in the face which made him bleed. Ban grow furious at Meliodas action, saying why would he accept Ban offer, but attack him. Meliodas told Ban that he did say he is okay with Ban killing him, but didn't say he wouldn't fight back. Meliodas then told Ban that Elizabeth think nothing of sacrificing herself and for their promise to save Liones, knowing that, he can't die right. Meliodas told Ban that despite what he is doing, Ban will be his friend, no matter what, but like him, he got things that he can't give up on. Hawk then count front Ban, saying if he will really what the horn would say and that isn't Meliodas his friend. Ban told Hawk that Meliodas was his greatest friend, but want Elaine to be back. Upset at this, Hawk said what if Elaine didn't come back, he will lose his friend and Elaine might not be happy about this. Ban told Hawk what should he do, as when Elaine died, he was depress, but when he met the other Deadly Sins, he kept himself distracted, but he still know that he will be alone forever, be it in this world or next, saying this world without her is like Hell. Hawk didn't understand Ban, but Meliodas said he understood Ban, but said that they should put their fight in a hold until they solve the current matter as the Deadly Sins, which Ban said he understand.

Meliodas than ordered Hawk to carry him to Elizabeth location where it is in Merlin old castle while he sleeps on Hawk to regain his strength. Hawk agreed and gladly took Meliodas to save Elizabeth and because he is his friend. Hawk and Meliodas later arrive to Merlin Old Castle where Meliodas was shock to spot the bleeding Elizabeth and the deceased Dreyfus while Hendriksen knew that Acid wouldn't work on Meliodas because of their "detestable power". Hendriksen went on to say that he was a Druid, who are sorcerers in a deep forest. Druid are also known to reveres Goddesses and nature, and shuns the abominable Demons. Hendriksen explain that when he first met Meliodas, he felt malevolent, massive powers coming within Meliodas which was greater power than Zaratras himself and couldn't get a single read on his thought which made Hendriksen feared, interest and admired Meliodas. However, Hendriksen admit that he now possessed the same power as Meliodas, until Meliodas quickly went pass him and carried Elizabeth without him noticing as he did it again to give Elizabeth to Hawk so he could take her somewhere safe as he told her that both of them will run the bar again if she survives to comfort her.

As Hawk was running away with the princess, Hendriksen was about to use Hellblaze on them, until Meliodas appeared and slice off his arm once more. As Meliodas overpower Hendriksen, the latter somehow got control of his sever arm and still use Hellblaze on the run away until Diane appeared to save them and crush his sever arm. Hendriksen was shock to see Diane well and not in near death like before, until King Guardian appeared behind him and smash him. Hendriksen rise up to see the five member of the Deadly Sins (Meliodas, Ban, Diane, King and Gowther) appeared and challenge him to a final battle. As Hendriksen taunt the Deadly Sins for being out numbered due to the New Generation transforming into Demons, Meliodas pointed out that he should check again. Hendriksen sense that all of the New Generations were stopped as they return back to normal due to Ban and King help while the other Holy Knight are currently surrounding the ruin castle. Hendriksen, however, was joyful to admit that the situation became more interesting and wonder how the Deadly Sins defeat the New Generation so fast, but admit that the Sins can't defeat him.

As the battle went with the Deadly Sins working together to fight against Hendriksen, the latter admit that he is invisible due to the demonic power, but when Diane trap him with Double Hammer, Meliodas explain to Hendriksen that demonic powers can heal wound, but if he is not immortal or something, it would have been pointless as he wouldn't completely handle it for a while. Hendriksen than smash Ban into the wall where the latter found the demon corpse and return to Hendriksen, smashing against the wall furious for having the demon while questioning him for having it. The wall break down to reveal the demon which shock the Deadly Sins. The Deadly Sins were shock to see the Red Demon corpse as Hendriksen explain that he found it in the Fairy King Forest long ago and how much of a bless it was to him. Hendriksen used the power of the Red Demon and summon wipe that nearly stab the Deadly Sins despite for Ban who used this to get closer to Hendriksen and slam him to the ground while furious, telling him that he can't beat him since he was the one who killed the Red Demon.

When Hendriksen was sent underground, Ban destroy the Red Demon in anger while they follow Hendriksen underground as they can still sense him and something greater. Leaving Diane behind due to her size as she is unable to fill inside the hole, the Deadly Sins traveled inside to discover Hendriksen who revealed that he has another Demon underground that he discovered years ago, which was a large sun flower head Demon knows as Gray Demon which is much higher than the Red Demon. Hendriksen took a blood sample from the Gray Demon's corpse and injected on himself, resulting to gain tremendous power-boost from the demon. Ban still attacked Hendriksen despite the warming Meliodas give to him, ending up half of his body blow up with ease. Meliodas along with the other Deadly Sins, were blown out of Merlin Old Castle and badly injuries due to Hendriksen new found power. Meliodas try to stop Hendriksen from getting Elizabeth by stabbing him, but the blade barely went in and was toss aside with ease. During Hendriksen assault on the Holy Knights and Deadly Sins, Meliodas protected Elizabeth from all of those attacks, but collapsed when he was no longer able to handle it. Meliodas pleads Elizabeth to escape, the latter refuses, leading Hendriksen unleash Dead End. When all hopes are seemingly lost, Hawk suddenly appears to save the paralyzed Meliodas.

Meliodas plead Hawk to escape, but Hawk took the attack, killing him in the process. Meliodas grow furious at his friend death, but not as much as Elizabeth which unlock her hidden powers and revealed her right eye with strange symbol. When Elizabeth healed everyone, Meliodas was unsure about Hawk as he knows that Elizabeth ability can't heal those who have been kill which brought Elizabeth to tears. When Hendriksen was about to kill Gilthunder, Meliodas charge toward Hendriksen, kick him in the face and punch him in the stomach which made Hendriksen collapsed on the floor while Meliodas told everyone to not loose hope while in his Black Mark mode once more. As everyone seem to lose hope as they continued their assault on Hendriksen didn't work, Meliodas ordered Gowther to use Broadcast to everyone to explain his plan which everyone was shock, but went along with it. Meliodas end up fighting Hendriksen head on while the Holy Knights launch their attacks on Meliodas and Hendriksen displease Hendriksen remain unaffected while Meliodas is taking damage. During the battle, Hendriksen realize Meliodas can't use Full Counter because his power wasn't healed, only his physical strength.

Despite Hendriksen trying to put Meliodas down, saying it is only futile to continued to fight him as Meliodas can't use Full Counter and was about to use Dark Nablua on Meliodas, but Meliodas continued to push on as the latter step inside Dark Nablua and punch Hendriksen, destroying the attack. Everyone continued to assault Meliodas with all of their powers at the same time while Elizabeth plea everyone to stop despite it was Meliodas plan to begin with. After Ban attack Meliodas, Hendriksen felt a incredible high power level coming within Meliodas which shock even Hendriksen. Gowther revealed that this was Meliodas ultimate attack as he doubles everyone power attack that he took and was about to unleash it on Hendriksen. Gowther also revealed that surviving this technique is 0.2% which shocks and scared Hendriksen into flying away, but was trapped in Wall by Griamor and Meliodas jump up toward Hendriksen while the latter ask why Meliodas is doing this for the people who framed and attack him, but Meliodas response that Hendriksen committed a sin for abandoning his friends to protect for powers and unleash Revenge Counter, killing and destroying Hendriksen body.

Meliodas later fell back down from his battle against Hendriksen as Elizabeth came rushing to his side. As the two got closer, Bartra cough and told them to be kept separated as he return from Camelot after being healed by Merlin. Meliodas and Elizabeth greeted the two from their return and after Bartra forgive the Holy Knights for their crime and cleared the Deadly Sins name, Elizabeth, however was still depress as Hawk was still dead from protecting Meliodas. While Ban grieve over Hawk dead body, Meliodas came closer to Hawk dead body, telling him if he makes it alive, he will give him the triple amount of leftovers he can eat. For unknown reason, the black matter on Hawk body started to fade, revealing that Hawk has been revived, but shrunken to smaller size, but this still greatly bring joy to the Deadly Sins, especially Ban. Elizabeth than put Meliodas face into her chest which is something she never done, but end up healing Meliodas with her rune eye while still tearing for joy as Meliodas and Hawk are still alive. Meliodas than embrace the princess, ending their adventure in Liones.

Current arc
As Liones was being rebuild due to the battle, Meliodas and Hawk watch over the injured and unconsciousness Elizabeth as she rest in her bedroom. Hawk wondered why Elizabeth didn't heal herself while she healed everyone else in the kingdom. Merlin appeared out of nowhere due to teleport, and stated that Elizabeth unlock her power without thinking which healed everyone else because she was thinking about others then herself. Even if Elizabeth had some magic left, she still wouldn't heal herself which led to Hawk tearing up, believing that Elizabeth should at least think about her health first. Meliodas and Merlin chat over the location of the Eternal Coffin of Darkness as it was no longer in Liones even with Merlin "Location" magic technique as it was revealed that a strange bird appeared and fly to the east. Merlin revealed that she told Arthur that she will be away for a while as she will rejoin the Deadly Sins for the time being which made Meliodas glad as it could save them, but still feel uneasy with her suspicion smile. Meliodas revealed that he still wanted to know what happened ten years ago while Merlin seem interested in Hawk, calling him a hero which made the tiny pig happy and befriend Merlin. Meliodas realize that he forgot something and went back to Elizabeth room while Hawk yelled at him that he shouldn't do something weird to Elizabeth while she sleeps.

When Merlin and Margaret appeared in front of Elizabeth room, Meliodas step out of the room with a grin which made some of them worried that he did something weird, until it was revealed that Elizabeth is up and healed for unknown reason. Hawk was overjoy to see Elizabeth standing again, but wondered why she is moving again. Merlin seem to know what Meliodas did as it was revealed that Meliodas held her hand and told her that he can't live without her which made her wake up. Meliodas took Hawk back to the Boar Hat as Ban feed Hawk with expired food until Gilthunder appeared as he is dress casualty and wanted to chat with Meliodas. The two sat down and enjoy the drink Meliodas offered as Gilthunder drink Bernia ale which he admit it tasted good. While the two sat, Gilthunder revealed that he is going to quite being a Holy Knight and become a wander as he need to clear his mind from his sin he committed as a Holy Knight despite he was working undercover and trying to protect Margaret. Meliodas didn't argue with Gilthunder because he is a man now, but still wonder how Margaret will take it. Ban then decided to tell Meliodas that he isn't just leaving the Boar, but quitting the Seven Deadly Sins to Meliodas surprise. The next day, Meliodas got a brand new uniform from Elizabeth which he planned on wearing from now on as the rest of the Deadly Sins got new uniform as well, expert for Merlin. The Deadly Sins end up celebrating the festival while working in the Boar Hat along with everybody else.

The next day, when Bartra was about to award the Deadly Sins and Hawk for their effort in freeing Liones, Meliodas notice Hawk has regrew back to normal size and that most Holy Knights were whispering behind Meliodas back. When Bartra was about to give the award, Meliodas yelled objection to everyone surprise.

Abilities/Equipment
As the leader of the Seven Deadly Sins, Meliodas is immensely powerful, and has demonstrated his superhuman strength through his ability to easily crush steel, with only his bare hands. He is also immensely agile, being able to easily avoid attacks of even Holy Knights. He was able to break free from Gilthunder's lightning bindings and also dodge his attacks, again, very easily. It was then revealed that the whole time, Meliodas was holding back his powers, and could easily slice a mountain in half by only using a stick. Meliodas appears to have bottomless strength as no matter how much Ban robbed his physically strength, Meliodas still had some until he was forced to use his black mark.

Meliodas has a mysterious mark on his forehead which only appears when he uses his full power. In the second instance, he was able to defeat Ban, despite the latter having robbed all of his physical abilities. After Meliodas somehow overcame the Goddess Amber's seal, the aura he emitted was akin to that of a demon, and the right portion of his body, from the forehead to his right knee, was colored black with spiral designs. Meliodas' abilities increased dramatically, allowing him to sever Guila's hand instantaneously before she could even notice and attacked Guila and Jericho with Full Counter even there was no attacks from the duo to reflect back at. Manipulating the black colored matter on his skin, Meliodas can form several different forms, including a wing-like structure around his arm which enables him to fly, and a pair of giant claws and blade to attack.

Meliodas has, twice, displayed black colored eyes, and a strange black colored symbol that appears on his forehead, which seem to grant him increased abilities. The aura he released was enough to frighten Golgius, a Holy Knight, into fleeing.

Abilities
