Omnimon is a Warrior Digimon whose Japanese name is derived from "I am the Alpha and the Omega", and whose English name is derived from "Omni". 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 "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. It bears the Crest of Courage on the Brave Shield Omega, and a combined symbol of the Crests of Courage and Friendship on its chest. The DigiCode on its Grey Sword reads
