Omegamon Zwart Defeat is a Holy Knight Digimon. It is a form of Omnimon Zwart that was injected with a virus program by someone and turned into a berserker. It views all Digimon that move into its field of vision as menacing enemies, and anyone who approaches it is attacked without mercy. The raging virus program and lingering vaccine program within its body clash with each other, causing it to become unstable, and so its wounded body continues to run wild and tire without ever recovering. Occasionally, it will restrict using both of its weapons in order to suppress any damage the instant the vaccine program pushes back and it regains its sense of self.
- Supreme Cannon (Garuru Cannon): Freezes the opponent with frigid, absolute zero shots that it fires from the "Garuru Cannon".
- Transcendent Sword (Grey Sword): Slashes with the "Grey Sword".
- Grey Sword - Spiral: Charges the opponent with a fierce spin using the Grey Sword.
Omegamon Zwart Defeat resembles a damaged version of Omnimon Zwart. It wears multiple bandages around its armor. Its Garuru Cannon is fractured, and its Grey Sword is broken, although it can project a red laser sword on it and it wears a black cape. The DigiCode on its Grey Sword reads "TERMINAT" (), shortened from Omnimon Zwart's "TERMINATE" () due to broken form.
