A metallic copy of Sonic the Hedgehog. Designed to look like his counterpart, Metal eventually gave himself the ability to speak and built himself a more unique form, becoming Neo Metal Sonic. This version of Metal often has a lot of spite for his creator, Doctor Eggman, almost as much as he does for his organic counterpart.

Since he's a robot, his voice should have a monotonous quality, though I would still like the actor to be able to emote. Think something like GLaDOS from Portal - unfeeling, but still capable of inflections that indicate scorn, or malice, or sarcasm. Also, don't add any modulation effects to your voice, I want to hear the raw performance.
