Which Street Fighter spin-off series features 3D gameplay and EX characters?

The Street Fighter spin-off series featuring 3D graphics and EX characters is Street Fighter EX. Developed by Arika in partnership with Capcom, it began as an arcade game in 1996 and brought polygonal visuals to the franchise while keeping battles on a mostly 2D fighting plane.

That combination is the key detail: Street Fighter EX looks three-dimensional, with characters and arenas rendered as polygons, but it does not play like a fully free-roaming 3D fighter. Players still fight primarily from a side-on perspective, with familiar special moves, Super Combos, blocking, and canceling mechanics.

The series introduced original fighters such as Skullomania, Garuda, Hokuto, and Doctrine Dark alongside returning characters including Ryu, Ken, Chun-Li, and Zangief. Its sequels were Street Fighter EX2 and Street Fighter EX3, released in 1998 and 2000.

A common mix-up is confusing Street Fighter EX with Street Fighter IV, which also used 3D graphics but arrived much later as a mainline title. Arika later revisited the EX characters in Fighting EX Layer.
