Omnimon X is a Holy Knight Digimon and carrier of the X-Antibody. One of the "Royal Knights", it was fused from the Virus Busters WarGreymon and MetalGarurumon due to the powerful wills of everyone who wished for goodness. It is a Digimon who has combined the special qualities of two bodies, so it is a multitype warrior which can fully demonstrate those abilities, for any given situation. It is equipped with the invincible "Grey Sword" and "Brave Shield Omega" for its WarGreymon-shaped left arm, and the "Garuru Cannon" and missiles for its MetalGarurumon-shaped right arm. As for the mantle on its back, it is automatically deployed when it dodges an opponent's attack, or when it is flying. Due to the X-Antibody, theoretically, other Digimon are unable to defeat Omnimon. This is because it acquired the , an ultimate force which, in battle, is able to instantaneously read ahead and respond accordingly. It is an ability that draws out and raises Omegamon's combat sense and potential, under any circumstances, to their utmost limits. Also, it never loses as far as Network Security is concerned.
