Zero Suit Samus

Zero Suit Samus is a character from the Metroid series. When Samus uses her Final Smash, Zero Laser, her Power Suit breaks apart, turning her into Zero Suit Samus.

Character description
Samus spent her childhood with her family on the mining planet K-2L. The planet was raided by Space Pirates, who were looking for bounty. The leader of the Space Pirates, Ridley, killed most of the people in Samus's colony, including her parents, and then destroyed the planet. Orphaned, Samus was found by a bird-like alien race known as the Chozo, who brought her to their home planet Zebes. Samus was infused with Chozo DNA to give her a strong resistance to foreign environments, then trained as a warrior and given one of the alien race's artifacts, a powered exoskeleton called the Power Suit that biologically entwines itself with Samus's mind and body.

She enlisted in the Galactic Federation Police, but later left because her commanding officer Adam Malkovich sacrificed his little brother to save the team and some three-hundred refugees when a large fusion drive was about to explode. Samus, who is 6 ft 3 in (1.91 m) in height and 198 pounds (90 kg) in weight, now works as a freelance bounty hunter, and is called on by the Galactic Federation to execute missions "because of her superior skills and sense of justice". Samus is motivated at least in part by wrath as well as an accompanying sense of duty, since her "bounty hunting" helps the galaxy get rid of unsavory elements such as the mysterious lifeforms known as Metroids, who can drain life energy and are frequently used as biological weapons. She also takes the opportunity to exact revenge on the pirates who murdered her family. Typically, one of her suit's arms carries a cannon, which can be charged to shoot an extra-powerful blast, a limited number of missiles, and various beams. Samus's suit can collapse into a sphere, a mode called the Morph Ball, allowing her to roll through tight areas such as tunnels. The suit can scan objects to learn more about them, and has a grapple beam used to cross large distances, such as chasms. Since Metroid II: Return of Samus, Samus has been accompanied by her gunship, which is used in the games to save progress and restore health and ammunition.

Samus's suit can be enhanced by power-ups, the first introduced being the Varia Suit. When the Varia Suit is destroyed, however, Samus dons the less protective Zero Suit. Both of those are worn by Samus in the Super Smash Flash and in the Super Smash Bros. series.

Samus typically works alone. Before Metroid: Other M, she had never spoken in any of the games in the Metroid series other than Metroid Fusion and the opening cutscene of Super Metroid, conversing mostly through text dialogue. In the first Metroid, her gender was kept a secret until the end of the game—the instruction booklet for the game referred to her character as male. If the player completes the game quickly enough, she is first revealed as female at the end of Metroid. Typically emotionless, Samus reveals some of her true self in Metroid Fusion. Without her suit, she let slip some emotions while dealing with her artificially intelligent computer. In Metroid II: Return of Samus, Samus bonds with a Metroid, which later sacrifices itself to save her from Mother Brain in Super Metroid. Seeking revenge, Samus destroys Mother Brain in a scene that is "more than a little emotionally charged". In the Chozo's scrolls, Samus is recorded as The Newborn, an "orphaned warrior filled with vengeance". Thanks in part to her Chozo heritage, the Chozo consider her the hope of their race. The Galactic Federation sees her as the protector of the galaxy, and the Space Pirates refer to her as the Hunter.

In Super Smash Flash 2
Zero Suit Samus' inclusion is hinted at because of her inclusion in Super Smash Bros. Brawl and the reveal that she would appear in the classic Power Suit. Her moveset is taken directly from Brawl. Her sprites are based on her appearance in Metroid: Zero Mission which was also the basis for her appearance in Brawl. She is still ranked 28th of B- tier on the current tier list.
