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. He appeared in full kabuki costume with a massive build and long pink hair. Retu fought against Maki in his dojo in Japan, but was defeated and killed by her. Maki kicked him through the dojo's window, avenging her family. Coincidentally, this was the fate of Belger in the original Final Fight.
- It is quite possible that Sodom orchestrated Retu's rise to power, although this has not been proven.
- Retu is parodied as one of the bosses of The Simpsons arcade beat-em-up game.
