Cycloid Beta and Cycloid Gamma are two secret characters that debuted in Street Fighter EX Plus (1997) an update to SFEX (1996).

They have almost no story background and use special moves of other characters, the main differences between the two are the colors and different special moves.

There was another Cycloid in the sequel Street Fighter EX2 and the Street Fighter EX3 character Ace is probably a more advanced Cycloid.

According to the Japanese version of SFEX Plus α, Cycloid Gamma is revealed to be a secret weapon made by Pullum’s father, Balba, in order to take down a criminal organization (Shadaloo?).

The Cycloids in the Game-Art-HQ Art Tribute to the 25th Anniversary of Street Fighter in 2012


Back in December 2011 we organized a  big Art Tribute for the 25th Anniversary of the Street Fighter series.

And while the Cycloids and the SFEX games are not developed by Capcom and therefore, not counted “canon” we included them and everyone else from the Street Fighter EX games in our project. You can see them here
