The Kraxians are the main villains in Bakugan: Kraxian Conquest . They're trying to take over Earth since their home planet Kraxia is dying. In battles, the Kraxians use transformer-like Bakugan called Mechtogans. The Kraxians are also cowards. If they want to escape from a battle, they use a special device called The Light to "vanish" from the battle.
