## Profile

### Identity

Caster-Saber's true identity is Ultron Sigma, the fusion consisting the mechanical threats Ultron and Sigma, sharing their ultimate goal to obliterate all organic life. They are the greatest enemy of the Marvel-Capcom Alliance and one of the most powerful entities in this combined universe. With their might combined together, and the Infinity Stones (specifically the Reality Stone and the Space Stone) at their disposal, they seek to conquer all of their universes.

They later transformed into their final form Ultron Omega, after they failed to harness the Soul Stone due to lacking a human soul.

#### History

When Thanos attempted to breach the forcefield of Abel City to reach the Reality Stone held within it, he enlists the help of Ultron, who is promised control of the city in exchange for his help. Upon crossing the forcefield he encounters Sigma, and, them recognizing each other's hatred for biological life, merged their two universes together and merged themselves into the being Ultron-Sigma, with the intent of turning all natural beings into "perfect" cybernetic ones.

## Abilities

Being the complete gestalt of Ultron and Sigma, Ultron Sigma possesses both individual machines powers combined, along with two of the Infinity Stones, the Reality Stone and the Space Stone. As such, he is one of the most powerful beings seen from the merged universes, with his power comparable to a god's. Their usage of the Reality and Space Stones was the cause of the Marvel universe and Capcom multiverse to merge into one, and they can use the stones in conjunction to tear open holes in reality and rain energy meteors down upon their foes.
