Play Butt-Ugly Martians : B.K.M. Battles Online

Remember that weird early 2000s cartoon with the ugly alien trio? This GBA shooter actually captures their bizarre charm pretty well. You pick between B-Bop, 2T, or Do-Wah—each handles differently, with 2T being my go-to for balanced stats. Their "butt-kicking mode" suits make them look like rejected Power Rangers, which somehow works.

Levels are classic side-scrolling chaos: blast through waves of Bog’s minions, hunt for keys to unlock doors, and grab power-ups that turn you into a temporary wrecking ball. The boss fights get surprisingly tough—some of those space cavern baddies don’t go down easy. And yeah, Stoat Muldoon shows up to be annoying, but you can shut him up fast if you find that memory-erasing crystal.

28 levels sounds like a lot, but the password system means you won’t lose progress. The GameCube connectivity thing was neat back then, though good luck finding a copy of Zoom or Doom these days. It’s janky in that early GBA way, but if you ever wanted to see those ugly Martians actually kick some alien butt, this does the job.
