Play Bad Badtz-Maru Robo Battle (Japan) Online
Bad Badtz-Maru and friends pilot tiny, absurd mechs—think lollipop weapons and Sanrio faces—in this stripped-down GBC brawler where everything’s cute and chaotic.

Game Overview
Okay, picture this: Bad Badtz-Maru—Sanrio’s little troublemaker penguin—but he’s strapped into a giant robot, ready to throw down. That’s basically this weird, wonderful Japan-only Game Boy Color fighter in a nutshell. The sprites are tiny and super cute, like someone shrunk Gundams and gave them Sanrio faces.
You pick from Badtz-Maru and his friends (each with their own ridiculous mech), and then it’s just straight-up chaotic brawling. The controls are simple—no crazy combos here—but there’s something weirdly satisfying about watching these chibi robots smack each other with oversized weapons. My personal favorite is the one that looks like it’s armed with a giant lollipop.
It’s definitely not the deepest fighter out there, but the charm is off the charts. If you’ve ever wanted to see Hello Kitty’s edgier cousin pilot a death machine, this is your game. Just don’t expect Street Fighter—it’s more like someone mashed up a toy box with a 90s arcade cabinet.
