Ultimate Muscle: The Path of the Superhero (2003) was the Game Boy Advance counterpart to the GameCube release. Featuring a roster of Kinnikuman characters, it delivered handheld-friendly wrestling action with simplified mechanics. Grapples, slams, and super moves mirrored the console version, albeit in 2D sprite form.

The story mode followed arcs from the anime, adding context to matches. While not as deep as the GameCube entry, it captured the humor and charm of the series. For handheld fans, it was a solid companion piece that expanded Kinnikuman’s reach into gaming.
