Power Suit

The Power Suit is one of Samus Aran's suits from the Metroid series. In Super Smash Bros. Brawl, activating Samus's Final Smash, the Zero Laser, will cause her armor to break apart and Samus will transform into Zero Suit Samus at the end. The pieces of the armor can then be picked up by any fighter and thrown like an item. The armor will also break and drop if the player selects Zero Suit Samus from the character select screen, which is done by holding down the shield button when selecting Samus, and when she enters the fight or if the player repeatedly alternates between Samus's up and down Taunt to transform mid-fight. Activating Zero Suit Samus's Final Smash, Power Suit Samus, will rebuild the armor. In Super Smash Bros. for Nintendo 3DS / Wii U, Samus's armor will no longer break apart after her Final Smash, due to Samus and Zero Suit Samus becoming separate characters, and Zero Suit Samus's Final Smash is replaced with Gunship as a result.

While the armor is called the Power Suit in Super Smash Bros. Brawl, the armor itself resembles the Varia Suit, specifically from Metroid Prime.
