Chun-Li is a character from the Street Fighter series of games. She was the first female playable character in the series when she debuted in Street Fighter II. She is most known for her muscular thighs, as well as her Lightning Kick maneuver. When she's not fighting, she works as an undercover Interpol agent, trying to track down the person who killed her father, who happens to be M. Bison. She continues being a police officer after his defeat, then eventually retires and teaches martial arts to children.
She made her first appearance in Street Fighter II, then appeared in every single Street Fighter game since. Chun-Li has also appeared in every crossover game that Capcom has made, including the Marvel vs. Capcom series, SNK vs. Capcom, Street Fighter X Tekken, Capcom vs. SNK, and Tatsunoko vs. Capcom: Ultimate All-Stars, as well as the two RPGs, Namco x Capcom and Project X Zone.
