Galactic Wrestling: Featuring Ultimate Muscle (2004) was a PS2-exclusive follow-up to the GameCube’s Ultimate Muscle game. Based on the Kinnikuman anime, it featured wild characters with superhero powers battling in wrestling rings. The game leaned heavily into spectacle, with massive special moves and colorful, over-the-top arenas.

Gameplay built on AKI’s systems, with grappling, reversals, and finishers delivering both strategy and arcade chaos. The roster was larger and included classic and new characters from the anime. Though niche, it was praised for capturing the spirit of Kinnikuman and remains a cult classic among fans of wrestling and anime hybrids.
