Bullmon

Bullmon is a Mammal Digimon. It armor-digivolved due to the "Digi-Egg of Hope". Its appearance is that of a fighting bull, and it possesses tremendous charging and destructive power. However, due to the fact that it is only capable of charging forward, and that it always charges forth at full speed, it is incapable of reversing or turning. Not only that, it has a fairly short temper, and a weakness in that it gets agitated the moment it sees anything red.[3]
