Chun-Li is a significant female fighter from the Street Fighter series. First appeared in Street Fighter II (Or Street Fighter 2), she has since appeared as a player character in nearly all subsequent games in the series. Chun-Li is notable for being the first female playable character in a fighting game, earning her the status of "the first lady of fighting games".
Chun-Li is a Chinese martial artist and Interpol agent, whose father was killed by M. Bison. Because of this, she seeks to destroy Shadaloo and bring Bison to justice. After Shadaloo is gone for good, she becomes a martial arts teacher and continues her work as a police officer.
In M.U.G.E.N, Chun-Li was made by various authors.
Kazmer13's Chun Li is one of the few Street Fighter characters given a fighting style that doesn't work like the respective game they're in, and instead working more like a Mortal Kombat character. Its sprites are from Street Fighter 2 with various MK2 and MK3 spriterips. It can also perform the game's trademark fatalities.
WhiteMagic2002's take on the strongest woman in the world is based off Marvel vs. Capcom: Clash of Super Heroes. While it is missing a Hyper from said game, this version manages to be rather source accurate. As an added bonus, it also contains various new fancy, flashy, and visually appealing effects.
