Dr. Eggman employed the Big Arm during his initial invasion of Angel Island, only for it to be defeated by the heroes aligned against him. He would later employ a rebuilt or duplicate version in his efforts to rescue Metal Sonic from the Distant Abyss Zone, and use it to fight a monstrous creature inhabiting that Zone.
- Before it was utilized in the comic, the Big Arm was featured on the cover of Best of Sonic the Hedgehog Villains.
