Guest C

Guest C is a Pre-loaded Mii available for use in titles that feature Mii support, which includes Wii Sports Games. He's also the default male Mii in the Mii Maker.

Super Smash Bros. for WiiU & 3DS
The design of the Mii Brawler used in promotional material and in-game renders is based on an edited version of Guest C. His skin is brighter (as the default male Mii in Mii Maker has light skin) and his hair has a different design, along with the hair being black in color instead of brown.
