In most games, characters have one or more win quotes that they use indiscriminately, but sometimes special win quotes are used in special circumstances. For example, in The King of Fighters '94, each character has special win quotes against each of the 8 teams; in Street Fighter Alpha, players can choose one of four win quotes by holding certain button combinations after winning a battle; in Street Fighter III: Giant Attack, characters sometime use special win quotes if they finish the battle with a certain move; and in SNK vs. Capcom: Match of the Millennium, players can input their own win quotes in edit mode.
Some win quotes have characters break the fourth wall, such as Chun-Li's Marvel Super Heroes vs. Street Fighter win quote in which she suspects the game is set on the easiest difficulty setting; or are in-jokes referring to other video games, like Sakura's Street Fighter Alpha 3 win quote in which she says she prefers "street fighting to sparring in rival schools."
Guile: Are you man enough to fight with me?
M. Bison: Anyone who opposes me will be destroyed.
