Street Fighter Alpha Series, known as Street Fighter Zero (ストリートファイター ZERO?) in Japan, Asia, South America and Spain, is a Series of fighting games by Capcom originally released for the arcade for the CPS II hardware. The games introduce several new features, expanding on the Super Combo system previously featured in Super Street Fighter II Turbo, with graphics drawn in the same animated style Capcom employed in Darkstalkers and X-Men: Children of the Atom. The plot of Street Fighter Alpha is set after the original Street Fighter but before Street Fighter II and thus the game features younger versions of established characters, as well as characters from the original Street Fighter and Final Fight, and a few who are new to the series.
