Metal Sonic

870
Metal Sonic is a robotic doppelganger of Sonic the Hedgehog created by Dr. Eggman, and the primary second-in-command of the Eggman Empire. Most of the time, Metal Sonic is Dr. Eggman's right-hand and completely obedient enforcer, though there have been several incidents of him going rogue, most famously in Sonic Heroes. In addition to being programmed to serve Dr. Eggman, Metal Sonic carries only one goal in mind: destroy Sonic using abilities superior to his. He is one of Sonic's most powerful archenemies.
