Samus Aran Corruption

Samus in her Power Suit in Metroid Prime 3: Corruption.

The Power Suit is Samus Aran's standard battle armor, it basically has no upgrades and is the suit you start out with in just about all of the games (except for Metroid Prime, in which you begin the first level with what appears to be the Varia Suit, which is also the version Samus wears in the Super Smash Bros. series).
