The evil heart hidden within Gammamon was unleashed, Digivolving it into a violent Digimon. GulusGammamon rejects outside interference and thinks of nothing but battle. When it gets its hands on the opponent in front of it, it will continue its assault until their life is extinguished. Its battles are brutal, and even if its limbs are crushed, it still continues attacking without concern.
GulusGammamon uses its special move Dark Pales to crush the enemy with dark flames gathered in its hand, or Desdemona to hurl those dark flames while preserving their might. It also uses Dead End Skewer to pierce the enemy’s vitals with its tail, annihilating them with pinpoint accuracy.
