Samus Aran is the protagonist of the Metroid series making her debut appearance in Metroid. She is a professional bounty hunter who often fights against the Space Pirates. Samus appeared in Super Mario RPG: Legend of the Seven Stars.
Samus Aran was an inhabitant of the Earth colony K-2L. Following a space pirate raid on the colony, which led to her parents' death at the hands of Ridley, Samus Aran, as the lone survivor, was adopted by the bird-like species Chozo and was injected with their DNA, making her faster and stronger than the average human. She then grew up to be a bounty hunter, going all across the galaxy armed with her Arm Cannon and Power Suit to complete her missions across the universe, from planet to planet.
In this game, Samus Aran makes a cameo appearance. She can be found sleeping in the guest room of the royal castle of the Mushroom Kingdom. When Mario talks with her, Samus tells him that she is resting for her fight with Mother Brain.
In Super Smash Bros. series
Samus makes her first appearance in the Super Smash Bros. series in the original Super Smash Bros. as a starting playable character. Samus is a heavy, yet floaty character. Her design is based off her appearance from Super Metroid.
Samus returns as a starting selectable character in Super Smash Bros. Melee, in which her moveset has been tweaked. Her design is still based off her Super Metroid appearance. Her new side special move is the Missile. Samus returns in Super Smash Bros. Brawl, with an embellished design drawing aspects from multiple Metroid games, though it closely resembles the Super Metroid-based design used in Melee. After using her Final Smash, the Zero Laser, her Varia Suit will fall off, thus making her become Zero Suit Samus.
Samus returns as a playable character in Super Smash Bros. 4 and Super Smash Bros. Ultimate. Her appearance now matches the design used in Metroid: Other M, albeit with minor cosmetic additions. However, she can no longer turn into Zero Suit Samus, who is now a separate character.
- Samus is the first female playable character to be the protagonist in her own series.
- Samus is the only character who appeared in every Super Smash Bros. game, unless Jigglypuff is counted.
- Samus has consistently been the heaviest female character across all games. She would then share this trait with her Echo Fighter, Dark Samus, in Ultimate.
- Samus and Peach are the only female characters to have Echo Fighters. Dark Samus is the Echo Fighter of Samus and Daisy is the Echo Fighter of Peach.
