Epsilon

Epsilon is the "Unknown Energy Manipulator: Test Model" from Mega Man X: Command Mission. Epsilon masterminded the revolt on Gigantis Island and is the leader of the Rebellion Forces. Proud and relaxed, he is usually very quiet. Epsilon was the only Reploid to survive the Supra Force Metal infusion experiments, giving him heightened intelligence and strength capabilities. All other volunteers in the experiment either went mad (maverick) or perished outright. Though Epsilon retained his sanity, he realized he could try to reproduce the same results that he had on other Reploids, and thus staged a revolt for Reploid Freedom, believing that Reploids could evolve past what humans had made them to be, and become more advanced. He led the Rebellion with great charisma and leadership, so much that Scarface and Ferham were willing to put their lives at stake for him. His body also contains a sizable chunk of Supra Force Metal, still.
