(黒い狂戦士 Kuroi Kyousenshi?)
|Debut||Digimon World: Next Order|
|Prior forms||Omegamon Zwart D|
Omegamon Alter-B is a Digimon. The "Black Digitron" secretion, deliberately mixed in by an unknown entity, caused Omegamon Alter-S to change into this black form. Although its power is heightened while it is in this form, it comes at the price of losing its sense of self, leaving it in a berserk state.
- Supreme Sword (Garuru Sword): Launches consecutive attacks from the Garuru Sword on its right arm.
- Transcendent Cannon (Grey Cannon): Launches consecutive attacks from the Grey Cannon on its left arm.
Omegamon Alter-B resembles an enhanced version of Omegamon Zwart. It has red horns and wears multiple belts on its chest, and its cape is now black and grey. Its pauldrons are larger and have golden spikes. Its BlitzGreymon and CresGarurumon heads are black and have red gems on the eyes and golden teeth, while the BlitzGreymon head has red horns, with the front horn being large and the back horns being small. It has a rhombus red gem with a golden frame on its chest, and another red gem on its waist. It also has a golden spike on each side on the waist, and a red spike on each knee. It carries the "Garuru Sword" on its right arm, and the "Grey Cannon" on its left arm; this is an inversion from the "Grey Sword" and "Garuru Cannon" of other Omegamon variants.
