Omnimon X
When Omnimon gains a lot of experience within fights versus the Digimon with the X-Antibodies, he has slowly gathered the Antibody's data and entered himself an X-Evolution. In this form, not only he gains the ultimate attack move All Delete, but he gains an ability known as the Omega InForce (Omega gaIned Force), one of the three InForce abilities exclusively bestowed upon members of the Royal Knights (the other two are Alphamon with the Alpha InForce and UlforceVeedramon with the UlForce). This ability lets Omnimon read what is to happen in the following moments during battle, effectively retaliating to any situation possible.''

Digital Monster X-Evolution
Omnimon appeared in Digital Monster X-Evolution as the leader of the Royal Knights during Alphamon's absence. Initially, Omnimon carried out Project Ark almost to the letter. He is a follower of Yggdrasil, the super-computer governing the current Digital World.

When Gallantmon confronted Omnimon about Yggdrasil, they were unable to agree about the nature of Project Ark and so they fought. Omnimon ended up killing Gallantmon. Shaken by his friend's death, Omnimon begins to seriously question Yggdrasil. But even so, he still carried out Yggdrasil's orders. It was only when Alphamon saved Omnimon's life and gave it the X-Antibody that Omnimon's eyes were finally opened to Yggdrasil's true motives. Transforming into Omnimon X, he destroyed Yggdrasil with his All Delete attack, resetting the Digital World as a result.

After Dorumon's Dragon Spirit is stolen however, Omnimon X sends Hikaru, Teru, and Masuken to another of the Holy Knights, Duke, while he attempts to track MetalPhantomon. He witnesses the birth of Dexmon, however, and is immediately beaten down by him until Hikaru and the others arrive to fight.
