Zero Suit Samus is a playable character in the fighting video game, M.U.G.E.N Trilogy. She is an alternate version of the original Samus and was confirmed on March 20, 2015 along with many other characters who appear in Super Smash Bros. Brawl. Alésia Glidewell (who is also the English voice actor for Krystal) provides the role for Zero Suit Samus in this fighting game, using voice clips recycled from various Super Smash Bros. games. As of December 30, 2020, Zero Suit Samus now gains a Japanese voice actor, Ai Kobayashi (who reprises her role as that character) in this fighting game.


While Samus has been shown without her Power Suit since the original Metroid, usually as part of an ending sequence, the Zero Suit first appeared in Metroid: Zero Mission, a remake of the original Metroid for Game Boy Advance. The original Metroid allowed Samus to be playable in a leotard using the well-known "JUSTIN BAILEY" cheat code; Zero Mission expanded on this by incorporating a playable, suitless Samus into the game's narrative for the first time, granting her a unique style of stealth-based gameplay. Ever since Zero Mission, Samus has appeared in her Zero Suit in every Metroid game except Metroid Prime Pinball and Metroid Prime: Federation Force, although the latter features a Zero Suit-inspired paint job for the playable Federation mechs unlocked via amiibo.

The Zero Suit covers Samus completely from neck-to-toe in a cyan, skin-tight bodysuit with magenta Chozo sigils on her back, left breast, and the back of her hands. While wearing it, Samus wears her hair in a ponytail, although she is occasionally seen with different hairstyles in different outfits (prior to the Zero Suit's debut, Samus would be more often seen with her hair loose). Although Samus' eye and hair color varied widely across early games, most current depictions consistently give her blonde hair and blue to turquoise eyes. Despite this, Samus' "Zero Suit" character design has varied in nearly every appearance. Initial appearances would depict Samus with a high ponytail with a red hair tie, long sidetails, and lean musculature. Metroid Prime Hunters featured a heavy redesign for the Zero Suit that was not used in subsequent games, with a more simplistic, gloveless bodysuit and a different hairstyle for Samus. Metroid: Other M featured another drastic redesign by changing Samus' eye color (now a more greenish hue), her general hairstyle (a lower ponytail and much smaller sidetails), her general build (now short and slim as opposed to lean and muscular), and the Zero Suit itself (which now has a more segmented appearance and is equipped with wedged heels). This general design was carried over to Metroid: Samus Returns, but with a few minor changes, most notably by giving Samus a blue hair tie and a more athletic body type akin to her Super Metroid appearance; an unused design for the game depicts her with an altered Zero Suit pattern, but she retains her Other M paneling in-game.
