Zeldris/Plot

Albion arc


After Hendrickson managed to remove the seal, Zeldris and the rest of the Ten Commandments appeared before the terrified former Great Holy Knight and Fraudrin in Dreyfus' body with Zeldris uttered Meliodas' name as if he knew him. After being informed by Fraudrin of the current events in Britannia, Zeldris suggested that they should head for Edinburgh Hill for recuperation of their severely drained magical powers due to the seal they're trapped in, which everyone agreed and left Zhuhur Valley by flight, leaving a terrified Hendrickson.



Arriving at Edinburgh Hill, Zeldris and his fellow Ten Commandments find a castle in ruins and concludes that it was Meliodas who caused the destruction of the castle as if there was a great battle fought there before noticing his brother Estarossa in a laid-back self, relaxing in the castle's ruins much to Zeldris' chagrin. After talking about the destruction of the Albions, one of them presumably defeated by Meliodas, making Galand decide to go and check it out. Zeldris stops him saying his cockiness was what caused them their lose before, but Galand leaves nonetheless, much to Zeldris annoyance. Later on, the Commandments continued to rest and recover their magical power through the souls of humans they devoured and were shocked when they sensed Meliodas regain his full Demon powers at Istar.

Istar arc


Suddenly, Meliodas appeared out of nowhere through Merlin's teleportation and casually greeted the Ten Commandments who were alarmed of his sudden presence, Zeldris attempt to fight but Galand stopped them because he was determined to finish off where he started. Meliodas battled and defeated Galand in less than ten seconds before warning Zeldris that the Seven Deadly Sins will defeat the Ten Commandments with everything they've got. In response, Zeldris and Fraudrin attempted to attack Meliodas from both sides, but he was teleported back to Istar. Afterword, Zeldris suggest the Ten Commandments to split up and move across the land to regain their magic faster while calming Galand down after his loss against Meliodas. However, Zeldris remained behind as Estarossa refused to move as he wanted to relax after being sealed for so long while Zeldris decided to look around.

Great Fight Festival arc


Zeldris is revealed to have toppled the Kingdom of Camelot's royal capital, single-handedly, seemingly having parted ways with Estarossa.

Later on he, along with the other Commandments, arrive to aid Drole and Gloxinia who are facing off against Meliodas. As he stands face to face with his brother, Meliodas immediately attempts to slash him across the chest. Completely unfazed, Zeldris was able to not only avoid the attack but cut Meliodas' arm off. Meliodas then kicks him in the face and attempts to reattach his arm, but Zeldris, unharmed, steps on it to prevent it from reattaching, and calls Grayroad over to place his Jubaku Ensa on Meliodas, to prevent him from escaping. Zeldris later tells a now severely beaten Meliodas that his death will be the first part of their revenge and if it were not for his betrayal, the Demon Clan would have not been defeated in the war.

Defensive Battle for Liones arc


A month after the death of Meliodas, Zeldris and the Ten Commandments continue with their conquest of Britannia. During the invasion of Liones, Zeldris manages to get several Holy Knights and civilians to fall under the effect of his Piety commandment and become the blind slaves of the Demon King and himself. After Fraudrin praised his commandment, he tells him how weak he is and is annoyed, then both feel the incredible concentration of power of Escanor and go to the castle to know what happens. There they witness the fight between Escanor and Estarossa, Zeldris is surprised that someone is able to battle his brother. When the fight moves out of Liones and Estarossa seems to win the upper hand, Zeldris says he has already decided, but Escanor manages to release an attack strong enough to obliterate Estarossa and send him away. Zeldris tries to help him, but only manages to be absorbed by the attack and sent remotely far away along with Estarossa.

Corand arc


It is revealed that Zeldris survived Escanor's attack. In Camelot, Zeldris senses Merlin scouting Camelot in search of Arthur Pendragon using Orlondi. He swiftly attacks the mage with his magic through Orlondi and manages to curse her, but she manages to escape before Zeldris can kill her, impressing him.

While Elizabeth tries to cure Merlin, Zeldris came to see who was trying to cure Merlin and was visibly shocked at seeing her again but quickly recovers. Zeldris immediately starts mockingly greeting her, saying it is been quite a while since they last met and calling her a pitiful woman before getting angry when Elizabeth demands he tells her what he means. Zeldris calls her "Cursed Goddess Elizabeth" and asks her if she still brings Meliodas suffering while revealing he is Meliodas younger brother. When Elizabeth confusingly asks Zeldris on his words, Zeldris realizes the rumor of the Curse is true and reveals what he knows to her while annoyingly answering that it is off course her when Elizabeth questions on Meliodas' lover. When Elizabeth smiles, Zeldris is shocked and asks her on it. He gets angry when she tells him of what she dreamed of was true, and angrily screams for her to remember what had happened.

Prelude to the New Holy War arc
Some time later in Camelot, Zeldris tries to remove Excalibur from its place, but he did not even budge it, as Zeldris comments on the blade's magic being completely different from that of demons

At that moment, a Gray Demon comes and informs him that over one hundred demons have been killed, but they still do not know who the culprit is. Zeldris is annoyed by this, and decides that he will personally punish the criminal.



Then, Zeldris is contacted by his father who tells him that Meliodas will replace him as the Demon King, and he is to accept his elder brother as his new king, much to Zeldris' anger. Reluctantly agreeing when the Demon King sternly told him to not argue and retrieve Meliodas, Zeldris telepathically calls the other Commandments but none of them responds to him except Gloxinia and Drole, who told him that they have abandoned the Commandments and are enemies of the Demon Clan. Disappointed and angered with the Giant and Fairy Kings decision, Zeldris responds by stripping them of their Demonic power and Commandments before cutting off contact without another word after saying that a Giant and Fairy could never properly work with the Demon Clan. Zeldris smirks unleashing his aura, saying he alone is enough to crush the Seven Deadly Sins, and he will show his father who is truly worthy of being the next King of the Demons.

At that moment, two demons, Cusack and Chandler, appears, much to Zeldris' pleasant surprise. Noting that his former mentor and Meliodas' former teacher's power is more than enough to fill in the vacancy of the missing Ten Commandments, Zeldris reveals to Chandler that his father has ordered him to rescue Meliodas and crown him as the new Demon King. He blatantly answers Cusack's evident criticism of the order by saying even he can never understand what the Demon King is thinking. When Chandler happily leaves to do so alone, Zeldris says aside from Chandler, there is no other demon more capable of defeating the Seven Deadly Sins. Right there, Estarossa wakes up momentarily from his coma, claiming that they do not leave him aside and asking if Meliodas is really still alive. Zeldris recommends him not force himself until he has healed completely. While they wait for Chandler, Zeldris and Cusack discuss the attitudes of the Pacifier Demon and his inevitable victory if he were to unleash his authentic form leaving aside his obsession with Meliodas.



When Meliodas finally returns accompanied by Chandler and Elizabeth, Zeldris receives him at the castle praising his guts. When Meliodas claims that he intends to become the Demon King, Zeldris affirms that he will be the one to have said position. After Estarossa shared his disagreement with Meliodas, the two jump to attack him. However, Meliodas manages to subdue both with his dark matter, immobilizing them against the ground with great pressure. Zeldris tries to prevent Cusack from intervening and can not believe that he can not move even with the power that his father gave him, recognizing the strength of his brother. After being released, Zeldris refuses to accept that Meliodas becomes the Demon King, knowing that he only wants that to break the curse that lies on him and Elizabeth. Meliodas says he wanted to achieve it by taking the magic that the Demon King had lent to Zeldris, but then says that he already understands that this will not be enough. Zeldris resumes his fierce attack on Meliodas claiming that he will become the Demon King, but he is easily overcome. When Meliodas catches him, he tells him that he knows the reason for his obsession with the throne, going on to tell him something that only Zeldris can hear. Suddenly, Zeldris decided to collaborate with Meliodas reluctantly, leaving Cusack and Estarossa impacted. Zeldris agrees that Meliodas will not reach his father's level with the borrowed power he possesses or training. When Meliodas reveals his plan to absorb the Ten Commandments to reach the power of his father, Estarossa asks Zeldris if that is possible, leading Zeldris to reveal that he has the Commandments of Gloxinia, Drole and Gowther, and quickly puts them away when Estarossa tries to take them. Zeldris uses the spell that removes Commandments in Estarossa but this does not work, revealing Zeldris that the only way to remove a Commandment from its bearer is that it is his consent or that he is unable to fight in response. Zeldris asks Meliodas how he intends to obtain the Commandments because they can not take them voluntarily as happened with Drole, Gloxinia and Gowther. There Estarossa asks what would happen if they were dead, revealing Zeldris that then the Commandment could be removed without problems of the corpse. Zeldris is surprised to discover that Grayroad was defeated by Merlin and that Meliodas has her Commandment. Zeldris affirms that Meliodas recognizes his place when he says that he can not accompany them to retrieve the other Commandments given that nobody would deliver them to a traitor of the Demon Clan. Before leaving in search of the Commandments, Zeldris warns Estarossa not to try to keep the Commandments for himself.



Following the weak trace of Melascula's magic, Zeldris arrives at the Boar Hat where he is confronted by Merlin and the other Sins. Zeldris claims not to know Merlin when she recognizes him, but when Merlin flies back to her original form, Zeldris identifies her as the girl who received the blessings of the Demon King and the Supreme Deity, impressing the other Sins.

Zeldris and Merlin go to heavens in order to have a negotiation for Melascula. Along the way, Zeldris tells the whole story about Merlin's past in Belialuin, which is heard by the Sins through a magical plant that Merlin left behind. When Zeldris ask about her intentions, Merlin also ask about the reason for what he is helping Meliodas to obtain the commandments and become the Demon King. When Zeldris denies given answers and insists that Merlin deliver him to Melascula, Merlin locks her into her Perfect Cube, forcing Zeldris to give her something in exchange for Melascula. Merlin requests that he hand over to Elizabeth and Arthur, but Zeldris denies because Meliodas would interfere with the first and his ignorance about the location or state of the second. Zeldris finally agrees to release all the Liones' Holy Knights and civilians who were under the effect of his Piety.



Zeldris insists to Merlin that he fulfills her part, but this is limited to rambling. When Zeldris warns her to cut her if she tries to do something, Merlin says she will not do anything. At that time, Ludociel, who possessed the body of Princess Margaret, attacked Zeldris from the Druid temple where Gilthunder was a prisoner. After Merlin escaped with Melascula, Zeldris emerges having survived and realizes that the Four Archangels are revived: He then attacks Ludociel with his Dies Irae.

Zeldris returns with Meliodas and their masters regretting that he did not recover Melascula's commandment and reveals to them that Ludociel and the other Archangels had been revived. When Meliodas reveals that the Four Archangels have allied with Elizabeth the Seven Deadly Sins, Zeldris delights in her escaping from Meliodas.

Some later, Zeldris and Cusack surprises Arthur prowling around the castle. When they ask him his identity, Arthur reveals to be the king of Camelot, allowing Zeldris to deduce that he is looking for Excalibur. Cath manages to distract the demons to give Arthur the possibility of escape.



When Arthur manages to find Excalibur, he is attacked on the back by Zeldris and Cusack, who show Cath completely wounded and defeated. There, Meliodas appears revealing that he have betrayed his friends, causing Arthur to defy them after brandishing Excalibur. While discussing with Meliodas the strange magic of the sword, Arthur manages to cut Cusack and Chandler in half and destroy much of the castle. Zeldris then attacks Arthur, but he blocks all his attacks without having to see them, which Zeldris recognizes as Mumyo no Mai. Zeldris wonders how he knows that old technique to which Arthur tells him not to underestimate humans, proceeding to attack him with Deathpecker. Both Meliodas and Zeldris recognize these techniques as those belonging to the ancient masters of the sword and understand that they are dealing with the power of Excalibur. Arthur manages to evade the attacks of Meliodas and Zeldris and deal with them blunt blows with Excalibur. However, these fail to make a dent in the two demons.

New Holy War arc


Just before the Holy War was unleashed, Zeldris gives Meliodas all the Commandments he had in his possession, including his own. When he can no longer wait for Estarossa, Meliodas proceeds to absorb the five Commandments in his body. Before this, Zeldris reminds Meliodas of the whole reason why he agreed to help him become Demon King and Meliodas says that he will keep his promise after becoming Demon King. Zeldris says he is counting on it and Meliodas then asks Zeldris for forgiveness for the kind of older brother he has been. Zeldris does not answer but looks away, implying he is contemplating forgiving Meliodas.



Zeldris watches next to Cusack the cocoon in which Meliodas was, affirming that the absorption of the Commandments was being carried out correctly and that the body of Meliodas accepted them without problems. Zeldris says that they should look for the other Commandments as soon as possible and deal with them.

While waiting for Meliodas to come out of the cocoon, Zeldris, Cusack and Chandler are met at the castle by the Assault Force. The three demons are faced with Escanor, Merlin and Ludociel. Ludociel personally confronts Zeldris, saying that it is the first time they come face to face, to what Zeldris responds that it will be the last.



When the battle begins, Zeldris watches as Escanor attacks Meliodas' cocoon to which he tells him to get it all out of his system. Zeldris, Cusack, and Chandler are then assaulted by Merlin's Double Impact. Ludociel happens to confront Zeldris, noting that his skill in swordsmanship is the fastest in all the Demon Realm. After a swift exchange of swordplay, Ludociel receives a small cut on the cheek, while Zeldris receives the same injury followed by a large cut on the arm. Ludociel calls him rude for hurting a woman's face, to which Zeldris response that Meliodas would never take away a woman's body for himself. Ludociel intercepts the advance of Zeldris with his Gold Shining. He is slightly surprised when Zeldris emerges unscathed, assuming it is the power of the Demon King. Chandler and Cusack depart when Zeldris assumes the position that will release his original power, worrying both demons. Zeldris affirms that Ludociel will see his full power.

Zeldris recalls what Meliodas told him when he convinced him to help him become the Demon King: that Gelda is still alive, and how he re-sealed her twelve years ago when she wanted to die. This makes Zeldris remembers the moment when he sealed the Vampire Clan, when Gelda tells him that while it is sealed she will remember all her days with him.



Ludociel claims that the victory in the Holy War will be for the Goddesses, but Zeldris tells him he has no interest in petty games like that. Zeldris then proceeds to use his original power, Ominous Nebula, creating an incredible force of attraction, which draws the Assault Force towards him. Zeldris claims that they must get out of their way, releasing an attack that leaves Ludociel, Escanor, Hendrickson and Gilthunder wounded against the wall. Zeldris creates another force of attraction, but Escanor and Ludociel manage to hold on to it, while Hendrickson and Gilthunder are kept away in safety by Merlin's teleportation.

Ludociel is carried away to attack Zeldris, however, is only repelled and embedded against the wall as last time.

There, Ludociel and Escanor decide to attack together. Ludociel uses his Ruby Shine to blind Zeldris with a bright light while Escanor causes a huge explosion with his Cruel Sun to camouflage their presences. Convinced that Zeldris will not be able to counterattack without being able to anticipate them, Ludociel and Escanor launch themselves on him, but to his surprise both are rejected in the same way once again.

Zeldris declares that it is time to stop wasting time and get serious, then increase the pressure and speed of his power. Merlin, already unable to escape with her teleportation, is at the mercy of the Zeldris attack who tells her that the first thing he will do is take away the Commandment. However, Escanor manages to shield her from the blow of Zeldris.



In his fury, Escanor releases his Crazy Prominence. Zeldris manages to divert with his sword all the mini suns that go towards him, but ends up causing a huge piece of the ceiling to fall on him. However, he is capable of destroying it and leaving unharmed without problems. Ludociel jumps to attack him once more, only so that he and Gilthunder who jump to protect him receive an even stronger blow from the power of Zeldris.

Zeldris declares that Escanor is the last one still standing. However, Escanor, assuming the power of The One, manages to advance without being absorbed by the Ominous Nebula. Seeing such a fact, Zeldris asks if he is some kind of monster. When Escanor tells about how he defeated Meliodas, Zeldris says that then he should not fight seriously because of the habit of underestimating his opponents that he developed due to being too strong. Zeldris declares that he is not like that and that he always uses his full power no matter who he faces.



Considering it a joke, Escanor attacks him with Rhitta. However, the Ominous Nebula manages to repel his attack, but only causing Escanor a few scrapes in the arm. When Escanor drops his weapon, Zeldris says he would do it to beg for his life, but he does not seem willing to do that. Escanor uses Divine Sword Escanor, colliding with the Ominous Nebula that is unable to repel it. Zeldris asks why a human takes such a risk in a fight between Demons and Goddesses, to which Escanor says that he does everything for the sake of his friends. Zeldris denies that Escanor can call Meliodas his "friend", stating that he has no place for those boring feelings and there increases the power of his Ominous Nebula, managing to push Escanor. However, the power of Escanor ends up being superior, breaking his Ominous Nebula and forcing Zeldris to intercept him with his sword.

Zeldris is forced to retreat, however, Escanor intercepts him with his Divine Spear Escanor, piercing his chest with his finger and leaving him very wounded. As Escanor returns to his night form before being able to finish him off, Zeldris needed less than a second to come to himself and one more second to reactivate his God power. This gives Ludociel enough time to strike him full with his Gold Shining, leaving Zeldris in very bad condition.



When Ludociel was about to finish him off, Cusack intervenes by stopping the Archangel with his swords. When Cusack asks Zekdris to let him take care of him, he agrees as long as he does not allow anyone to disturb Meliodas. Zeldris asks Cusack to make them understand the true scope of his power and that of Chandler as the demons of higher rank and superior to the Ten Commandments and himself. When Cusack tells him that he will be the one to surpass him, Zeldris does not understand what he is referring to.

When Cusack and Chandler are assaulted by Merlin's magical attacks, Zeldris fails to understand how she does it without showing any behavior. Zeldris is forced to intercept the attacks and cancel them with his God power. However, Zeldris begins to succumb to his wounds, and Ludociel slash him with his Ark blade.

When the spell that Gowther had used 3,000 years ago began to fall apart because Meliodas and the Demon King discovered the truth, Zeldris and Cusack, like all those who were under its influence, begin to suffer the effects of the spell that kept their memories altered. Thus, Zeldris recognizes that his supposed brother "Estarossa" is actually the Archangel Mael.

While Merlin and Ludociel suffer the impact of their memories returning, Zeldris, like Cusack and Chandler, manages to recover completely. Knowing that the psychological impact of the truth would cause great commotion the more closer a person was to Mael, Merlin wonders why Zeldris does not suffer any effect. Zeldris explains that it is because he never looked up to Estarossa as a brother anyway, in fact feeling relieved to discover that he really was not.

Zeldris says it is time for the second round, but Cusack tells him he and Chandler will take over. Zeldris asks him why they insist on fighting alone in such a situation. Cusack and Chandler declare that it is their duty to take charge of the enemy so that Zeldris can save his power to face the Seven Deadly Sins. There, Chandler and Cusack decide to join in their original form, talking about a demon called the "Original Demon", who was punished by the Demon King when trying to dethrone him and divided into two teachers for his children. Zeldris shows confusion to their words, wondering exactly what they are. Cusack gives a farewell to his disciple before converging with Chandler into the "Original Demon".

When the Original Demon is hitted by Chastiefol, Zeldris realizes that the Seven Deadly Sins are reaching Camelot, but he also feels another great magic reaching there.

As Chastiefol turns into True Sunflower and releases his power destroying most of Camelot, Zeldris saves the Original Demon by blocking the attack with his God power. Zeldris ask the Original Demon to take charge of Escanor and Merlin while he deals with Chastiefol. In the battle, Zeldris deals with Chastiefol True Increase and tells the distant King that he can't defeat him and that all of that is useless resistance. However, King changes Chastiefol into True Guardian and manages to hurt Zeldris with several physical blows. Zeldris then revelas to the Sins that they are not the only one reachin Camelot, since the Commandments that Mael have expelled are coming to rejoin with the five that Meliodas possess. As the four Commandments appears and joins with Melascula's Commandment, Zeldris apologies with Gelda as the five are absorbed by Meliodas's coocoon.
