Introduction arcEdit

Gilthunder sealing Bernia's underground water source

The river's underground water source being sealed by Gilthunder.

A day before Meliodas, Hawk and Elizabeth arrived at Bernia, Gilthunder had gone then to collect the taxes, and while doing so, had drank the very popular Bernia Ale. Even though it was the best ale Bernia had to offer, the Holy Knight insulted it and called it "only slightly better than a horse's urine". Mead, angered by this comment, dropped a bug in his next drink, which angered Gilthunder, who, in his anger, sealed the underground water source of the river in Bernia with a sword imbued with his lightning magic. That prevented the villagers from making the ale, which is the sole economic income for the whole village.[1]

He was residing in and governing Fort Solgales when he was informed of a child having pulled his sword[2], and he, deciding to confirm whether this was an accident or not himself, borrowed a spear from one of the guards and threw it directly at Bernia.[3] Meliodas, however, stopped the spear and threw it back, which resulted in the fort's destruction, and Gilthunder's realization that the Seven Deadly Sins were still alive.[4]

Forest of White Dreams arcEdit

Gilthunder fighting against Meliodas.

Upon arriving in the Forest of White Dreams by using a gigantic thundercloud and a lightning bolt, Gilthunder immediately immobilizes everyone with his lightning magic.[5] As Meliodas and Diane realize that he is a Holy Knight, Elizabeth recognizes him as Gilthunder, a Holy Knight very close to her father, and a brother figure to her, and initially doesn't believe that he was the Holy Knight who had dammed Bernia's water source, and is greatly surprised when she realizes that he was the one. Gilthunder, informing her that while her safety was the kingdom's priority, she was only a "grain of sand in the path to the Holy Knights' rule", and after releasing her, orders her to leave. She, however, refuses to do so or let him hard Meliodas and Diane, and when Gilthunder kicks a weakened Hawk out of the way, runs towards him.[6]

Gilthunder, points his sword at Meliodas' neck, stating that he wants to avenge his father, the deceased Great Holy Knight, Zaratras, and also wants to prove that he has surpassed him, leading Meliodas to recognize him as "Little Gil", Zaratras' son who would often follow the Seven Deadly Sins. Gilthunder then also declares that he is now stronger than any of the Deadly Sins, and offers to unbind the two to fight, but before he could do so, however, they easily break his spell themselves, with Meliodas instructing Diane not to interfere in their battle. As Gilthunder then attacks first using a powerful lighting bolt, the Sin of Wrath easily repels the spell back at Gilthunder, but the latter dodges the attack and moves behind the former, slashing him from behind and causing him to collapse.[7]

Meliodas, seemingly in his last moments, is question by Gilthunder for any last questions, with him asking for the whereabouts of the other five Deadly Sins. Gilthunder answers, telling him that while the whereabouts of three of them remain unknown, it is known that the Fox's Sin of Greed is imprisoned in the Baste Dungeon and the Grizzly's Sin of Sloth has perished in the Capital of the Dead. Hearing that, Meliodas quickly jumps back up[8], leading Gilthunder to realize that Meliodas let himself be gravely injured in order to obtain the information. He then proceeds to repeatedly attack him, only for Meliodas to dodge all his attacks. The Holy Knight eventually moves behind Meliodas again and points his sword towards his neck. Diane then suddenly interrupts the battle, lifts him with her hand, and despite his attempts to escape her grasp by discharging lightning, throws him from the forest.[9]

Gilthunder is later seen falling down from the sky into a church in a neighboring village. He walks out unscathed from the remnants of the collapsed church, whilst the priests and civilians cry for help.[10]

In the village that is also the entrance to the Capital of the Dead, Gilthunder informs King, who had formed an alliance with the Holy Knights to kill Ban, about Fort Solgales' and Baste Dungeon's destruction, the Weird Fangs' annihilation, and Ban joining Meliodas and Diane. He also warns King to not betray his trust, to which King asks him to keep things such as trust between humans and that his way was more convenient for both of them. Oslo, being as small as an ordinary dog due to not being threatened at all, then enters the room, and informs King about having found his target. King, showing Gilthunder the badges of Andre and his partner, who had been killed earlier by Oslo, then asks the Holy Knight to order his subordinates to not get in his way, lest he shall kill them along with his intended target, Ban.[11]

Gilthunder, along with a colleague, Howzer, is later ordered to confront and stop the invasion of the Northern Barbarians' army, which, numbering three thousand, had annihilated many knights. The two arrive on the battlefield on a flying dragon, and after landing on a lightning bolt created by Gilthunder, quickly defeat the entire army with ease. After returning to the castle, the Great Holy Knight, Dreyfus, commends them for their work, and after, Howzer questions him if that "errand" wasn't the predicted Holy War, assures him that it wasn't.[12] Gilthunder then expresses his suspicions of their foe, who has not been predicted, being the Seven Deadly Sins, since four of them had already reunited.

After a small discussion on their captain, Meliodas', abilities, Dreyfus mentions the "New Generations" of Holy Knights, with Gilthunder then reporting to Dreyfus about many Holy Knight apprentices, many of whom were considered failures, suddenly and mysteriously gaining incredibly strength, and that he senses someone of something to be the phenomenon's source. After Howzer leaves, Gilthunder goes closer to Dreyfus and informs him silently that the second Great Holy Knight, Hendrickson's, subordinates have been calling for several apprentices.[13]

When Howzer came back from Vaizel, Gilthunder reported told him that Veronica and Griamore were killed during the Vaizel event. Howzer ask how they doing to report all this to princess Margaret and Great Holy Knight Dreyfus, Gilthunder told Howzer that Dreyfus lock himself in his private room. Gilthunder look outside and said that things are going amiss and that Hendrickson group of Holy Knights has grown dramatically, and they were all New Generation, even stating in the past that Hendrickson and Dreyfus were even in powers but the balance is being broken by Hendrickson and wonder if this was another precursor of the Holy War.

Gilthunder wore his normal clothes and visited the first princess, Margaret Liones, to report Veronica's death. Once Gilthunder told Margaret of her sister's death, the latter grew anger at Gilthunder, believing that the Holy Knights were the one who killed her sister. Gilthunder told Margaret that it was the Seven Deadly Sins to which the latter refuse to believe since her father formed the group and the Holy Knights are the true traitors and cursed Gilthunder for working for them. Gilthunder was ordered by Dreyfus and Helbram to stop the Deadly Sins from attacking Liones along with Howzer, Guila, and Jericho. As they walk into Merlin's old castle, Howzer asks Gilthunder if Meliodas taught him how to use a sword but Gilthunder responded that he taught him the fundamentals of the sword. Howzer asked if Gilthunder could fight someone he used to look up to which Gilthunder respond that the Deadly Sins are the criminals while the Holy Knights are the ones who should stop them.

Gilthunder went closer to Diane, telling her that the Giants are dense beings since Diane is unaware how much trouble she is in now, but Jericho rushed in and tried to slay Diane who smashed her with her hammer, Gideon. Gilthunder ended up saving Jericho, who explained how powerful the Deadly Sins are with their Sacred Treasures. Gilthunder used his power, Thunder Bolt where he injured Diane as Howzer was forced to fight back and used Tempest which their combined their power created Dragon Castle and sent Diane flying. Diane manged to break free from Dragon Castle and landed back on her feet. Gilthunder witnessed his uncle Dreyfus' use of Break on the Deadly Sin and easily defeated her, sending the giant flying to the populated area of Liones. He soon accompanied his uncle and Howzer as they approached Guila, Helbram and Jericho who were near an incapacitated Diane. Gilthunder soon witnessed his old partner's and Guila's defection when the two rushed to protect Diane, who had their reasons to turn against the Holy Knights. Gilthunder remained silent during the conversation of Dreyfus, Helbram and Jericho trying to convince Howzer and Guila to come back to their side. After his uncle branded the two traitors, Gilthunder readies his weapon to battle his now-former partner and was seemingly caught by Howzer's Rising Tornado and bombarded by Guila's Shot Bomb in a form of a Combined Technique: Bomb Cyclone.

As the two rogue Holy Knights continue their assault, Gilthunder was revealed that he had not been caught by Howzer's twister all this time and attempted to strike Guila from behind with his lightning-infused sword, only to be blocked by Howzer. This, however, cancels their combined technique and frees Gilthunder's comrades in the process. Still locking weapons against each other, Gilthunder witnessed Guila being saved by Gowther from Dreyfus' Pierce and displayed no emotion when the Goat's Sin of Lust revealed his true identity to the Holy Knights at all. He later witnessed his uncle stabbing through Gowther and later both combatants then froze. When Dreyfus freed himself and collapsed due to mental injury, Gilthunder abandoned his battle with Howzer and helped his uncle to safety. Some time later, he and Dreyfus witnessed Helbram in his true form as a Fairy and full display of his power over the Sacred Tree.

Gilthunder started to battle with Meliodas, while Arthur fought with Hendrickson. Gilthunder started to overwhelm Meliodas with great speed and when Gilthunder was about to finish off Meliodas, Meliodas stopped his attack with just his fingers and was in his Black Mark mode.

Gilthunder battle against Meliodas

Meliodas and Gilthunder's battle rages on and shows that both of them are equally matched. Gilthunder sent Meliodas flying to a building, but Meliodas stops the crash by putting his feet inside the building. Meliodas asks Gilthunder if he really wants to have a death match with him, which Gilthunder responds 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 believes that the Deadly Sins have turned down that creed and betrayed the kingdom. Gilthunder claims that he is stronger than any of the Deadly Sins, but Meliodas just nodded and continued on their fight with full speed. Later on, Meliodas started to overpower Gilthunder, while the latter tried to fight back with all his strength, but with no luck. Meliodas tries to slice Gilthunder, but Hendrickson appeared and struck Meliodas which the latter dodged in time, Meliodas was surprised to see Hendrickson and saw Arthur was defeated. Gilthunder and Hendrickson decided to team up in order to defeat Meliodas, as he was their greatest threat. The Unnamed Holy Knight appears and helps the duo do battle against Meliodas.

As the trio starts to overpower Meliodas and knock him next to a building, Vivian, amused that Meliodas was mortally wounded, as he had not used Full Counter or his Demon powers, but Gilthunder sensed that Meliodas power was increasing instead of decreasing. Hendrickson said that they have miscalculated and knew where the eerie premonition came from. Hendrickson found out that the reason for Meliodas not fighting back is because Meliodas is heightening his utmost power and senses to unleash a one decisive attack. The Holy Knights combine all of their power together in an attempt to finish off Meliodas before he can unleash his attack. Hendrickson summons Hellblaze, Gilthunder uses Sword of the Thunder Emperor, and Vivian unleashes Quad-Element Destroyer as Meliodas summon his attack, Divine Slayer. However, Margaret comes running toward the battlefield to stop Gilthunder from hurting his hero, Meliodas. However, Meliodas, spotting something next to Margaret, unleashes his Divine Slayer to kill an invisible demon. Pleased with destroying the creature and with no time to dodge, Meliodas takes on the full force of Vivian's attack, leaving him heavily injured. Seeing this opportunity, Hendrickson rushes towards Meliodas to finish him off but is instead repulsed and has his arm cut off by Gilthunder. Gilthunder, with a tear in his eye, smiles and thanks Meliodas for setting him free from his curse.

As Gilthunder cuts off Hendrickson's arm, Hendrickson yells out in anger at the sudden betrayal. However, Gilthunder points out that he was never on his side to begin with. As Hendrickson tries to summon Hellblaze with his left arm, Gilthunder stops Hendrickson and sends him flying. Gilthunder asked Meliodas to leave it to him, as he was waiting for this moment for a long time to have his revenge against his father's murderer. After the long battle, Gilthunder stabbed Hendrickson and unleashed his full power of his Thunderbolt and defeated him. He then reunited with Margaret and joined Meliodas and his company who came after the battle along with Gilthunder's Holy Knight friends (Howzer, Guila, Jericho, and Dreyfus) to rescue Elizabeth. While heading to the castle, Gilthunder explained to Howzer that the Chimera is the reason why he worked for the Holy Knights because that creature would harm Margaret, and is lightning-immune, if he went rogue. When Howzer apologized for not being there to help him, Gilthunder accepted it anyway. Gilthunder remained silent when King Arthur introduces himself to the group.

Gilthunder and Meliodas being stabbed by Hendrickson

When Vivian teleported the group to the Lost Forest, Gilthunder held Margaret close to him as the Holy Knight mage proclaimed that they'll never find their way out of the kingdom. But suddenly, the whole group was teleported back and witnessed Vivian being teleported randomly almost immediately. It was then revealed that the one who was doing it was Merlin of the Deadly Sins who teleported the group to Liones Castle and freed Bartra and Elizabeth. During the event, Gilthunder and Margaret admit that they knew Dreyfus killed Gilthunder's father and that they were blackmailed by Vivian to keep quiet. After Dreyfus admit his crimes and sent to jail, the castle was attacked by Hendrickson who the latter awakened the Demon blood inside of the New Generation and made them into hybrid of Demons themselves. Meliodas and Gilthunder were furious at Hendrickson's cruel nature and attacked him, until they realized that Vivian took Margaret and Elizabeth hostage. Hendrickson then stabbed 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, Hendrickson explains that Gilthunder will never leave her as a corpse to her shock. Elizabeth decided to go along with Hendrickson to save Meliodas' life, to everyone's shock. Hendrickson accepted her offer and was only planning to spare Meliodas, but he will spare Gilthunder as a bonus. As Hendrickson left with Elizabeth, Margaret and Vivian were worried over Gilthunder's condition as Hendrickson's ability, Acid, was effecting him.

However, when Ban appeared and dragged Gilthunder, Ban tossed the weakening Gilthunder toward the monster, Jericho, to Margaret and Vivian's shock until Ban used Hyper Recover Speed to heal Gilthunder and Diane at the same time. Gilthunder, along with the other Holy Knights, rejoin and surround Merlin's Old Castle to prevent Hendrickson from escaping as the Holy Knights now know the true enemy. When the Holy Knights were troubled by the fact that the two Great Holy Knights were the true villains and the Deadly Sins were innocent, Gilthunder comforted them and convinced them to fight for the sins. However, when Hendrickson easily defeated the Deadly Sins with his new form, Gilthunder along with the Holy Knights still charged toward Hendrickson, but all were easily defeated. As the battle rage on, one of Elizabeth's friends, Hawk, was killed during the battle which awoke a large light beam that came from Elizabeth. When Gilthunder believed the light to be the after life, Margaret quickly explained that it wasn't as Elizabeth unleashed her true power while revealing that Elizabeth has unknowable healed many people in her lifetime. When Elizabeth's healing light healed all the Holy Knights, Deadly Sins and people in the city, it didn't heal those who have been killed and despite Gilthunder being fully healed, he still felt great fear as Hendrickson came closer to him, as Gilthunder believed there was no hope left until Meliodas kicked Hendrickson in the face, saving Gilthunder, and he regained his hope.

After Meliodas defeated Hendrickson, Bartra reappeared and regained order within the kingdom alongside Merlin. As the Holy Knights kneel for Bartra, the king thanked Gilthunder for protecting Margaret while he was unable to, which led to Gilthunder to request a private chat with the king which Bartra accepted.

After the major event, Gilthunder appeared in the Boar Hat as he is dressed casually and wanted to chat with Meliodas who was feeding the revived Hawk. The two sat down and enjoyed the drink Meliodas offered as Gilthunder drank Bernia ale, which he admitted tasted good. While the two sat, Gilthunder revealed that he was going to quit being a Holy Knight and become a wanderer as he needed to clear his mind from the sins he committed as a Holy Knight despite the fact that he was working undercover and trying to protect Margaret. Meliodas didn't argue with Gilthunder because he is no longer a child, but still wondered how Margaret will take it. The next day, Gilthunder bid farewell to Margaret, and the two shared a kiss. The day after that, Gilthunder is present in the Seven Deadly Sins´s ceremony. After the ceremony, Gilthunder, Howzer, and Griamore, thanked the Deadly Sins for sticking up for Dreyfus and Hendrickson despite what they had become, which led to Merlin telling them to find the truth.

This immediately sparks their curiosity, and the three leave Liones to learn more about the connection between the Great Holy Knight and the Demon Clan.

The new enemy overpowers the Holy Knights, and they succeed in killing it only thanks to the aid of an unexpected ally: Hendrickson, now free of the demon blood. After killing the Gray Demon, the three confront Hendrickson for his misdeed, and the latter agrees that it was his fault for all of their troubles.  However, he revealed what happened ten years ago between him and Dreyfus.  As it turns out, Hendrickson was briefly possessed by a demon who was trapped and injured at the bottom of Danafor.  This demon happened to be Fraudrin, a member of the Ten Commandments. However, Dreyfus offered his body to spare Hendrickson, which he did and continued to do so to this day. Hendrickson revealed that he was a changed man and wanted to free Dreyfus.  Hearing this, the group agreed to work together and train to defeat the Ten Commandments, but they still don't fully trust Hendrickson.
Howzer and Gilthunder training

Gilthunder and the others were soon taken to Istar, the sacred land of the Druids, where they were taken to train in the Cave of Training, but it was soon proven too difficult for them to handle. However, they attempted it once more when the Deadly Sins showed up to train as well, where Gilthunder is paired up with Howzer. Once in the cave, the two choose an Amber that holds a Clay Dragon, which is known to be immune to lightning and wind attacks. Gilthunder and Howzer end up arguing during the training, but soon worked together and came up with unique attacks for them to harm the dragons. In the end, however, Gilthunder and Howzer end up failing the training, but Jenna was still proud of them for coming up with new attacks on the spot.

After everyone finishes with their training, Gilthunder witnesses how Meliodas regains his strength that was contained in an amber goddess. When Meliodas asks Merlin to send him to where the Ten Commandments are, Gilthunder tries to convince him that it is crazy to face them alone. Meliodas says that he will only say hello to them.

After Meliodas returned after defeating Galand, he declares that they must end the Commandments by attacking them while they divide to cover all of Britannia. While everyone leaves Istar, Gilthunder wonders if the training really increased his strength. Hawk reads his power level increased from 1,970 to 2,330, which pleases him greatly. Gilthunder asks Hawk to read Meliodas' power level, determining it at 3,250. Gilthunder states that Meliodas is incredible for such amount. However, Merlin tells Hawk he skipped a zero at the end, leaving Gilthunder and Howzer stunned to learn that his power level is 32,500.

Noticing that it is an enemy different from the demons they usually see, the three decide to go with everything unleashing their Trinity Attack: Hexagonal Graveyard. This however does not harm the Indura in any way who easily incapacitates them with a cut of its sharp tongue.

When Griamore regrets that the Seven Deadly Sins are not there, Gilthunder says that they can not always just depend on them and gets up saying he can still fight.

When the Indura is about to kill them, Escanor appears and shields the three by taking the attack with his body. Howzer recalls that King told him that he had lost his Sunshine power, so he could not face the Indura clone in his state. However, Escanor affirms that he will protect the future of young people like them even at the cost of his life.

When Escanor is injured again trying to face the Indura clone, Gilthunder attacks it with his Raitei no Tettsui, only to fall again after no harming it at all. The three couldn't do anything but watch how Escanor is put in the verge of death after asking them to scape. However, Escanor is saved in the last second by Mael, who destroy the Indura and heals Escanor along with Gilthunder, Howzer and Griamore. 

The three hears with ashtoniment how Escanor ask Mael to return Sunshine to him, even with this means that the power will end killing him for sure after one fight.

While in middle of the battle with the Sins the Demon King stands with a new, gigantic and monstrous vessel created from the same land of Britannia, a frightened Gilthunder hugs Margaret.

King of Chaos arcEdit

Gilthunder suddenly leaves, Howzer and Griamore keep telling him that he must be there to congratulate Meliodas. Crying, Gilthunder explains that he can't imagine what the Sins must be going through with Escanor and that he can't even think to tell them. His friends agree with him, so Griamore offers the three to go out drinking that night.

As they walk the streets, the three talk about Escanor. Gilthunder states that Escanor's determination to risk his life was real and that until the end he kept a smile for them, which is a resolution that not everyone has. When Howzer says it will be like that one day, Gilthunder and Griamore call him cocky, angering him. Gilthunder, however, says he will succeed because, as Escanor said, the future of youth is as bright as ever. Gilthunder is surprised when Griamore is reluctant to go his house to drink.

After toasting, Gilthunder is glad that people can live without fearing the Demon King. Howzer wonder what kind of era will come with the gods gone, to which Gilthunder believes it will be an era of peace. However, Vivian suddenly appears saying that when the balance between light and darkness is broken, what will come is the era of chaos.

Gilthunder and Howzer are alarmed by Vivian's presence, and Gilthunder claims that Ludociel had killed her. Vivian affirms that it resurfaced as a phantom thanks to the power of love. Not understanding, Vivian explains that someone took her in her arms begging him to answer. Hearing her say how Dreyfus gave her words of love, Howzer asks Gilthunder if it's true, to which Gilthunder says Dreyfus said some things and then begged Hendrickson to heal Vivian.

Vivian then tells Gil that they "broke up" since her eyes opened with true love. Gilthunder observes her precooked to what Howzer asks if he falls in love with her, which Gilthunder immediately denies. He then asks what she meant by an era of chaos, what Vivian says is something Merlin always said.
