Samus in her fusion suit.

The Fusion Suit is a suit that Samus Aran can obtain in the Game Boy Advance video game Metroid Fusion. It is an advanced suit that is able to absord X Parasites for health and ammunition. It will also allow the protagonist to withstand the icy cold weather in some of the game's many areas. In Super Smash Bros. Brawl for the Wii, there's a trophy that the player can collect that's called Samus Aran (Fusion Suit). One of Samus' alternate costumes in the game is also modeled after the suit. In Metroid Prime, the player can change Samus' suit into the Fusion suit by linking the game with Metroid Fusion.

Trophy description

"During Exploration SR388, Samus is infected by an X Parasite and nearly dies. A vaccine created from Metroid cells saves her, but part of her suit already too infected with the x parasite and must be removed. This causes her to lose most of her abilities and weapons. This means Samus must gather her special abilities and fight to neutralize the threat of the Parasites on the space station ran by Biologic Space Laboratories."
