Firebrand is a new character confirmed to be in Ultimate Marvel vs. Capcom 3.
Firebrand is a type of gargoyle known as a Red Arremer. He will stand up to any threat posed to his home, the Demon Village, without any fear. Firebrand is considered to be an elite warrior among the Red Arremers, gaining him hero status among his peers.
A member of the Red Arremer race of demon gargoyles, Firebrand is considered a hero among his people for the deeds he has commited under the command of the demon Astaroth. He is called the "Red Blaze" due to his control over fire magic.
As a young Red Arremer, Firebrand embarked on a journey to stop his home dimension of the Makai from being destroyed by the undead king of destruction, Breager. He collected magical artifacts while trying to reach his enemy, making him more powerful each time. After winning a magic candle from Lucifer, Firebrand became one of the most powerful of his species, and defeated Breager. Breager is resurrected twice after this, but Firebrand always kills him again.
Due to his alliegances, Firebrand can be considered an enemy of Arthur, although it is likely the two have never personally met. However, Arthur has fought many Red Arremers while trying to save his princess
