- Great Muta, which he has wrestled as often throughout his career, switching back and forth between this character and his real name. Great Muta is a mysterious gimmick where he spits green or red mist and plays mind games to distract his opponents. Muta was originally billed as the son of Japanese wrestler Great Kabuki who used a similar gimmick. The two are not related in real life. Originally he wore face paint, which was later exchanged for a mask after he shaved his head. The Great Muta gimmick is the gimmick most fans of the United States know Mutoh for, as he wrestled as The Great Muta throughout the late '80s and early '90s for the NWA, and in his later stints in WCW with it.
- Kokushi-Muso, a gimmick used only for a few shows. It is a play off of Jinsei Shinzaki's mystic character known as Hakushi. Hakushi means "White Messenger" while "Kokushi" means "Black Messenger", and "Muso" means "Monk". Under this character, Muto keeps some of the mannerisms and moves used as Great Muta, mixed with moves taken from Hakushi.

- Super Black Ninja, was used in World Class Championship Wrestling in Texas and also was used in the World Wrestling Council in Puerto Rico.
