Biography
Mastermind's early life may be that of his comic book counterpart.

Mastermind is the leader of the Inner Circle, and his Inner Circle agents are Marsh, Rat and Neuron. A year ago, he and his group multipulated Jean Grey under their control to have her transform into the Phoenix, and make her do battle against her fellow X-Men, which then resulted to Jean's death.

A year later after causing Jean's death, Mastermind traveled to the Tohoku region of Japan with his fellow agents. There, he took the form of Japanese scientist, Jun Sanada, in order to work for Yui Sasaki.
