Also known as: ゼロスーツサムス, ゼロスーツ
A Skin Tight Blue Bodysuit worn by Samus Aran in the Metroid series. The suit first appeared in Metroid: Zero Mission and has later appeared in many other games since. It traditionally serves as an underlayer she wears underneath her armor, such as her Power Suit (Metroid). While wearing it, she's often equipped with a Paralyzer, though as a rule, Samus fighting in the Zero Suit is reserved for extreme circumstances where her armor is unavailable.
The suit's appearance differs slightly between games. In Metroid: Zero Mission, the suit has black highlights on the legs and arms. In Metroid: Other M, the suit has dark blue highlights. In Super Smash Bros for 3DS/Wii U and Ultimate, the suit has glowing yellow High Heels and Bracelets. Metroid: Samus Returns concept art features yet another look that sports even more angular darker patterns around the whole suit, but this specific design does not actually appear in-game.
