The Zero Suit Body Suit in some early appearances is a skintight full-body jumpsuit worn by Samus Aran underneath her Power Suit , and appears after many recent Metroid game endings, and in some parts of the games. The suit first appeared in Metroid: Zero Mission after Samus initially escaped from the surface of Zebes. While in orbit, Samus was shot down by a fleet of Space Pirate ships. In order to re-escape from the planet, Samus needed to infiltrate this ship to find a small escape vessel—this is what was expected to be found within the ship at the very most. Luckily, Samus came across the Ruins Test during her infiltration mission, granting her a more advanced Power Suit than before. In Metroid: Samus Returns it is the best ending of Normal Mode by completing the game under four hours.
