Because of Sephiroth's popularity, he's made quite a few appearances in various Video Games. After the release of Final Fantasy VII, his very first outside apparence was as a selectable character in the fighting game Ehrgeiz, which also featured other characters from Final Fantasy VII.

Sephiroth also appears in the English and Final Mix versions of Kingdom Hearts, an optional boss fight in Kingdom Hearts II, and he has a cameo in the Itadaki Street games.

After nearly 10 years, he made his long awaited return to the Final Fantasy VII universe in Crisis Core -Final Fantasy VII-. Sephiroth is also the villain representing Final Fantasy VII in Dissidia: Final Fantasy, a Final Fantasy based fighting game.

He's also made some oddball, quirky apparences. Sephiroth is a downloadable Sackboy costume for Sony's Little Big Planet, and there's a Chibi-Sephiroth loading animation for the Final Fantasy Anthology port of Final Fantasy VI.
