DefeatGreymon is the opposite of VictoryGreymon and has a rivalry with him. He appears when VictoryGreymon is defeated by another mega and if his tamer feels resentment towards that digimon, he changes to DefeatGreymon. If he defeats the same species of digimon that defeated his VictoryGreymon form, he changes back to VictoryGreymon, and may change back and forth easily.
Revenge Sword-attacks with his sword.
Defeat Burst-sends a huge surge of energy at the opponent.
