Based on the video game franchise from Sega-Sammy Group. Sonic is a carefree blue hedgehog who runs very fast but he finds himself pursued by a group of echidnas for his power. His guardian Longclaw the Owl gives him a bag of golden rings that can send him to other planets. He winds up on Earth, mainly in the town of Green Hills, Montana where an incident causes him to knock out power across the entire Pacific Northwest. Roboticist and scientific genius Doctor Robotnik is enlisted by the United States Department of Defense to uncover the source of the outage. He comes across Sonic who is longing for a friend, but after seeing how Sonic's power fuels his robots, Dr. Robotnik wants nothing more than to capture Sonic.
