Omnimon
Omnimon is the Digimon created when WarGreymon and MetalGarurumon DNA Digivolve together, resulting in a stronger Digimon. His body is covered in white armor adorned with black, blue and yellow markings. His left arm ends in WarGreymon's head and his right arm with MetalGarurumon's, giving him two primary attacks (Transcendent Sword and Supreme Cannon). The cape he wears flows over the width of his body.In Digimon X-Evolution,he bears half of the each symbol that represent the Crests of Courage and Friendship on his chest.

The name "Omnimon" is derived from "omni", an English prefix meaning "all". His Japanese name, "Omegamon", derives from the "omega", the last letter of the Greek alphabet. With Alphamon, he represents Alpha and Omega.

An Omnimon serves as the vice-leader of the legendary Royal Knights, servants of the god of the Digital World, Yggdrasil.

 Variations / Subspecies 

Omnimon X / BlackOmnimon

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 begun 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.

 Attacks 
 * Grey Sword: Slashes with the Grey Sword. The Sword may also emmit flame from its edges.
 * Garuru Cannon: Fires colossal energy balls at foes. The Cannon may also be fired as ice energy, in e.ball form or beam form.
 * All Delete: The most powerful "anninihilation" attack in Digimon history; its name derives from the Digimon kana engraved upon the Grey Sword, which starts to emit lights of destruction upon the attack's activation. He uses this attack at the end of Digital Monster X-Evolution, which reset his former master and the Digital World itself.
