Epsilon

"I will not run from this fight. For I know that this bridge must be crossed to achieve our ideal. They will tremble before the power of Epsilon!"

- Epsilon

Epsilon (イプシロン, Ipushiron) is is the "Unknown Energy Manipulator: Test Model" and a villain Mega Man X: Command Mission. He serves as the leader of the Rebellion Army and acts as the game's main antagonist up until the final chapter due to the clever manipulation of Colonel Redips.

History
Epsilon orchestrated the revolt on Gigantis Island and is the leader of the Rebellion. Proud and relaxed, he is usually very stoic and quiet, his presence accentuated in this vein by his unprecedented (for a Reploid) African features. 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 and became a 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. He even showed the intelligence to keep the two of them as his main hands, as even Botos seemed to hold a bit less of his trust in comparison. His body also still contains a sizable chunk of Supra Force Metal from the experiments, hidden underneath his black torn cloak which is reminiscent of X6's Sigma (the rods on his shoulders are also reminiscent of the X7 Professor Sigma). Epsilon's name and motif share similarities with Sigma in general, as both are large, skilled, visionary Reploids named after a letter of the Greek alphabet.

Throughout the game, Epsilon makes attempts to control Giga City's resources while crushing the Resistance that opposes him. Realizing he needs force to make others listen to his ideals, he resorts to creating a missile armed with Supra-Force Metal to keep his foes at bay. Eventually, X and his team make their way into his fortress to confront him. After Scarface falls in his name, Epsilon takes them on himself only to lose. As he tries to continue fighting, X brings him down with his buster.

After the end of the game, Epsilon was deferred of all Maverick charges posthumously, most likely due to the restraint he showed in not killing any innocents during his activities (having banished the humans from Giga City without harm, simply forbidding them to return) and the fact that his whole Maverick status came about as a result of Redips' manipulation of events.
