Savant is of another dimension, gathered by Ubiquitor to assist in her destruction of other universes.
Savant was able to defeat Hollywood and Vision and force them to battle one another, giving Vision basic knowledge and restoring Hollywood's animosity for his old friend. Savant was ultimately defeated when he tried to absorb the immense knowledge of Main Frame (Vision). He was then captured and placed in the Stockade, a prison planet.
