Thakatos the Hedgebat

Thakatos is Shadow and Rouge's other kid. He was abandoned as an abomination when he was about 3, and was raised by Zavok, thus becoming his protege. Later, Zonic captured him and imprisoned him in a dumpster. Dark Visor accidentally awakened him on a search for the Planet Egg of Lost Hex. He returned to Möbius and attacked his brother, who destroyed him together with Sonic Jr.
