Pyrus is the Faction of Fire, one of the six possible Factions that can be found on Bakugan. Redesigned from the Pyrus from Bakugan Battle Brawlers, Pyrus features a redesigned symbol, but keeps the attributes of aggression and fire from its earlier counterpart.
Pyrus is used by one of the main protagonists of both the Battle Planet and Armored Alliance anime, Dan Kouzo. Pyrus is not restricted to be a Faction of the protagonists, as there are antagonists that utilize it as well, such as E and Duran Dane.
In Bakugan Battle Planet, Pyrus Bakugan generally have low B-Power, but high damage. To compensate, they have cards that allow battles to be decided by damage rather than B-Power. Their main Tag-Word Ability is "Fury", which triggers when they have no cards in their hand.
