Also known as: オメガモンX, オメガモンX抗体, オメガモン(X抗体)
An alternate version of Omegamon (Omnimon), who changed using the power of the X-Antibody. Alternatively, it is formed from the fusion of WarGreymon X-Antibody and MetalGarurumon X-Antibody. It has acquired a unique ability called the [u]Omega inForce[/u], which lets it predict any foe's moves and act accordingly, making it virtually impossible to defeat. Its ultimate technique is All Delete, a slash from the [u]Grey Sword[/u] which erases anything it touches from existence.
In the movie Digital Monster X-Evolution, it was given to him by a dying Alphamon.
