Shadow

Shadow (シャドウ) is a boss from Mega Man X: Command Mission.

Role
Initially appearing deployed to Giga City's Lagrano Ruins as a Maverick Hunter alongside X and Zero, he'd actually defected towards the Rebellion Army in secret, in one of the Command Mission storyline's last important pre-game plot events. He reveals himself to be a traitor when he, X and Zero confront Epsilon atop the Ruins. Later, he confronts X and company in the Gimialla Mines where he reveals the existence of the powerful alloy Supra Force Metal, as well as the fact that he betrayed his comrades and pledged allegiance to Epsilon for this. Despite using the Supra Metal, he is defeated when Zero appears and joins the fight in order to get revenge for his betrayal. However, before his destruction, he makes one last attempt at Zero with his pulverizer cannon, only to be intercepted and countered by Spider, who took the blow for Zero and then destroyed him, earning Zero's respect and trust. Ironically, Spider would be revealed in some capacity (as himself and/or Colonel Redips) to have manipulated the entire situation for the exact same reason Shadow became a pawn - the Supra-force Metal.

Personality
Shadow is extremely ambitious, and will backstab anybody he needs to for his own personal gain. Even as Shadow was losing to X and Zero, he showed no remorse for his betrayal.
