Retu appeared in full kabuki costume with a massive build and long pink hair.
Retu was the leader of the revived Mad Gear Gang. Apparently, Retu attempted to take the place of former Mad Gear head Belger, but failed. Retu fought against Maki in his dojo in Japan, but she defeated and killed him by kicking him through the dojo's window, avenging her family. Coincidentally, this was the fate of Belger in the original Final Fight.
