Butt Ugly Martians: BKM Battles is a 2D action-adventure game for the Game Boy Advance, based on the early 2000s animated TV series Butt Ugly Martians. The genre blends side-scrolling and platforming as players take on the role of the three Martian protagonists—B.Bop-A-Luna, 2T Fru-T, and Do-Wah Diddy—as they harness their Bio-Kinetic Modules (BKM) to combat enemies and navigate through various levels. The game emphasizes combat, exploration, and the collection of power-ups to thwart their nemesis Emperor Bog's evil plans to conquer Earth.
