Digimon X-Evolution
He is the confident leader of the Royal Knights, initially carrying out Project Ark almost to the letter. He is a follower of the word of Yggdrasil, a super computer governing the current Digital World. In X-Evolution, he is the main policing power, although he acts against informants and those betrayed with unprejudiced force. When Gallantmon confronted him about Yggdrasil, they were unable to agree about the nature of Project Ark and so they fought, ending with the other Knight's demise. This event is what made Omnimon seriously start to question Yggdrasil, shaken as he is by his friend's death. But even so, he still carried out Yggdrasil's orders.

It was only when Alphamon saved Omnimon's life, and gave him a X-Antibody in the process, that the Knight's eyes were really opened to Yggdrasil's true motives. Becoming Omnimon X, he destroyed Yggdrasil with All Delete, resetting the Digital World as a result. Omnimon later met up with Gallantmon X on top of a mountain.
