Zero Suit Samus

Zero Suit Samus is an alternate form of Samus that originates from the Metroid game, Metroid: Zero Mission. In Super Smash Bros. Brawl, she made her debut as a playable fighter, where she could be playable after Samus releases her Power Suit. Zero Suit Samus also returns in Super Smash Bros. for Nintendo 3DS / Wii U, though as a separate character from the normal Samus.
