Hold on, it looks like Millium wants to tell you something.
Hey-hey! White Rabbit here! Lammy scanned this article and said it contains unmarked spoilers for all Trails games. Turn back now if you don't want to get lasered! Okay, byee!

McBurn (マクバーン), also known as the Almighty Conflagration (劫炎(ごうか))[Note 1] and the Blazing Demon (火焔魔人(かえんまじん)), is associated with Ouroboros as Enforcer No. I.


McBurn's primary motivation in his missions is to find an opponent capable of forcing him to fight at full power. He has abandoned missions that he felt couldn't bring out the fire in him, as shown during Class VII's raid on Helmut Albarea's fortress.

Similar to Rean Schwarzer, who is "mixed" in his chest, McBurn is mixed throughout his entire body. He wields the sword Angbar (アングバール),[Note 2], one of the weapons forged through Divergent Laws and handed to him by Ouroboros' Grandmaster.

Hello there, beautiful. May I have a moment of your time?
Please be aware spoilers for Trails of Cold Steel III and IV may be present in the following section. Hit [Show] on the right if the show must go on. Adios, amigos!

Originally Demon Lord Mea Cu Barud Ruaung (魔神メア=ク=バルウド=ルアウング), king of the Outside,[JP 1] McBurn ended up in his current form after he collided with an ordinary human upon his visit to Zemuria in around S.1156.[1][Note 3] He would live without memories of his previous life for the next five decades.

It is unknown why or exactly when he joined Ouroboros. He joined it in or before S.1194, as he was involved in Ouroboros's raid on a rival organization in that year. He was one of the organization's three most powerful operatives; alongside the Seventh Anguis, Arianrhod the Steel Maiden, and Enforcer No. II, Loewe, whom he was well-acquainted with prior to his death due to his strength.

There we go, the end of spoilers. Thank you for your time!

Trails of Cold Steel II

McBurn was one of the four Ouroboros members (along with Vita Clotilde, Duvalie and Bleublanc) who works alongside the Noble Alliance during the Erebonian civil war, in the society's efforts to advance their Phantasmal Blaze Plan (which McBurn isn't interested in as he only desires to fight a strong opponent). He first crossed paths with Class VII outside of Bareahard and fought them alongside Duvalie, fighting restrained at first, and then immediately overpowering his opponents after Duvalie was knocked down by them. During the game's intermission, aboard the Pantagruel, McBurn has a conversation with Rean wherein he reveals that Rean is "mixed" in a similar way to him (referring to Rean's ogre power that activates when he is enraged/passionate). However, Rean is only mixed in his chest, whereas McBurn is mixed in his full body.

He is last seen fighting Class VII in the third stratum of the Infernal Castle. There, they manage to force him to bring out his more powerful form as the Blazing Demon, wherein his hair turns gold and his powers are amplified. Just as Rean is about to summon Valimar, Victor S. Arseid jumps in to duel McBurn and allow Class VII to progress. McBurn summons the Angbar and then begins to fight Erebonia's strongest swordsman.

It was later revealed that Victor's lungs were injured after his duel with the Blazing Demon, and his strength as a swordsman diminished (which contributed to him being defeated by his student later on).

Trails of Cold Steel III

Alongside Arianrhod, Campanella and the Stahlritter, McBurn works to reclaim the Phantasmal Blaze Plan from Giliath Osborne, who stole it from underneath Ouroboros at the end of the civil war. He is first seen in Crossbell, looking to find Vita Clotilde who had since disappeared from the society. There, he fights and overpowers Class VII at Orchis Tower and later at Stargazer's Tower, working alongside Campanella both times. He participates in an experiment with the Aions in the area. He also appeared during the events of the game's third chapter in Lamarre Province, sparring with Wallace Bardias who is able to hold back his flames, and taking an interest in Gaius Worzel due to him having became a Dominion.

At the end of the game, he teams up with Arianrhod to guard the first roadblock inside the Gral of Erebos. As he summons Angbar, Gaius, Laura S. Arseid and Emma Millstein (carrying Vita's staff) decide to take over the fight to let the rest of Class VII continue inwards. When McBurn observed the apparent death of Victor when the Courageous exploded, he regressed to his normal form, regretful at never having got the chance to fight him again.

McBurn was impressed at the sight of the Ebon Knight, remarking that it might be capable of utterly overpowering him.

Trails of Cold Steel IV

McBurn first combats the party at the Black Workshop where he fights alongside Ines and Ennea against Crow Armbrust, an enraged Rean Schwarzer and a turncoat Duvalie. Seeing Rean in an enraged state prompts McBurn to fight

He did not participate in the attack on the Pantagruel, but appeared in a long-range communication, where he introduced Victor S. Arseid to the group.

McBurn is later deployed Orchis Tower, working with Victor to defend the Magical Barrier Generator from Class VII. He explained to Sharon that he was only interested in finding a worthy battle. Laura later broke the curse's grip on Victor after successfully replicating the Arseid school's signature move. As a result of losing Victor, Alberich sent a Leviathan-type Magic Soldat to assist McBurn, but this simply enraged the Enforcer, who attacked the Leviathan. He was surprised that it possessed anti-magic armor, but before he could destroy it, the Vander family arrived and disabled it. McBurn then decided to withdraw out of respect for Laura and Victor. Seeing that the group could be potentially worthy opponents, he showed them a glimpse of his true form before he teleported away.

McBurn is then met as the final opponent in Tuatha De Danann that Class VII has to fight before reaching Osborne. Before the fight, he explains how he came to Zemuria 50 years ago from a world Outside it, and how his normal body is that of a human from Zemuria. He also comments on how both the Salt Pale and the Gnosis drug used by the cult in Crossbell are tied to the Outside just like him. McBurn knew that in order to regain his memories, he had to return to his "true form", and the transmutations the world underwent due to the Great Twilight and the ensuing World War provided a perfect opportunity for him to do so without twisting reality and space, the way the Salt Pale did.

McBurn then fought the party in his true form as a demon lord, even withstanding an attack from the Originator Zero sword by Valimar. Afterwards, McBurn returned to his human form and confirmed having finally reacquired his memories. He withdrew his hostilities from Class VII, but was not willing to work with them to defeat Osborne due to his new goal of confronting Campanella, Vita, Mariabell Crois and the Grandmaster. He seemed upset with Ouroboros and Campanella, suggesting he realized he was manipulated by them. Before teleporting away, McBurn gave Rean a single-use power that he could use during his final Rivalry with Osborne and Ishmelga.

  1. The Japanese word 劫 is a Buddhist term for an aeon or kalpa (कल्प) in Sanskrit. His alias 劫炎 can, therefore, be alternatively interpreted as the 'eternal blaze' or, as a representative of the current era, the 'first flame'. The significance of his alias is currently unknown.
  2. Though the localisation term differs, Angbar in Japanese is written in the same way as the Flame Dragon of the Five Dragons of Altago in Ys Seven.
  3. Exact time unknown. From S.1206, it happened "50 years ago",[2] but it may be earlier or later than S.1156.
