Sonic Hedgehog Ultimate Robotnik Duels Game

Okay, so Sonic Hedgehog Ultimate Robotnik Duels is one of those weirdly fun Flash-era fighting games where the roster makes zero sense (Mario? Raiden?!) but you roll with it because punching Robotnik as Knuckles never gets old. You pick from like 15 characters—some obvious, some random—and then it’s just straight-up brawling with simple controls. No fancy combos, just running around and spamming fireballs or whatever your character’s move is.
The AI’s kinda janky (this is a Flash game), but playing against a friend is chaotic in the best way. Silver Sonic’s weirdly OP if you figure out his timing, and yes, I totally picked Cannon Head just to see what would happen. Spoiler: he shoots cannonballs. Shocking.
P1 uses arrows to move and M to attack, P2 gets WASD and G. That’s it. No tutorials, no frills—just pick a freak and fight. It’s the kind of game where you lose half an hour arguing over who’s cheating when someone picks Shadow.
