On his chest is branded his symbolic kanji of 'mu'. Gouken's Horror themed costume has him imagined as an 'evil' counterpart he wears but a brown loincloth and shorts, with chains bound on his right arm and left leg. Gouken's fifth alternate costume has him wearing a red leisurely haori with black pants and a drum hanging off the belt, while accessorized with black wrist guards and brown leather body straps similar to those of the aforementioned yamabushi with wings on the back and a tengu mask. Gouken's fourth alternate costume has him imagined as Poseidon, the Greek god of the sea.

Gouken's third alternate costume is an outfit worn by the Yamabushi, who are Japanese mountain ascetic monks who followed the Shugendō doctrine. Gouken's second alternate costume is an altered gi with a conical hat similar to those once worn by ashigaru, foot soldiers employed by the samurai of feudal Japan. Gouken's first alternate costume has his gi top removed he now sports bandages on his forearms and a rope on his back, extremely similar to the one found on Akuma's first alternate costume.

In his most recent Street Fighter IV appearance, Gouken wears a single sleeved, gray-colored karate gi and sports a long, white braid of hair adorned with a single prayer bead. Gouken is most often depicted as an elderly yet very well-built man with a white beard and prayer beads around his neck.
