Metal Sonic



Metal Sonic is a Sonic lookalike robot created by Dr. Robotnik during the four years Sonic sent on Space Colony ARK. Metal Sonic was originally made as a replacement to convince Robotnik's partner Rouge to stop helping Tails make a rocket to reach the ARK, though failed to do so. Metal Sonic is powered by a Refractor located within its torso.

Abilities
Metal Sonic's body is comprised of microscopic nanites, allowing its form to take on any appearance within reason. It can project a purple diamond energy field used for both offense and defense and also channel an electric current through its metal body.

A jet engine in its torso allows Metal Sonic to reach speeds nearly rivaling Sonic's own.

Following an encounter with Emerl, Robotnik modified Metal Sonic to copy the abilities of its opponents. It is nowhere near as sophisticated as Emerl's technique, however - Metal Sonic can only copy one ability at a time and only use it once before needing to scan and copy again.
