Street Fighter Wiki

Cycloid Gamma (サイクロイドγ Saikuroido γ?) is a video game character from the Street Fighter EX series, first appearing in in Street Fighter EX Plus as a secret character. Alongside Cycloid Beta, it is a humanoid weapon created by Shadaloo that is capable of mimicking moves from other fighters.



The Cycloids consist of Cycloid-β (a.k.a. Cycloid Beta), who is a blue 3D-model of a human male with no facial features, and Cycloid-γ (a.k.a. Cycloid Gamma), who looks similar to Beta, only Gamma's a wireframe model. Both use attacks borrowed from other characters and don't speak. Their origins are unknown. Amusingly, its body shines and still does so even when the game is paused.


Street Fighter EX series[]


Gamma is a secret weapon made by Pullum Purna's father, Balba, while being forced to work for Shadaloo. Balba halted Gamma's development near its completion, being finished by Shadaloo's technology department. Cycloid-γ occassionaly escapes from Shadaloo to learn new skills and become a better fighter.[1]
