A comical, light-hearted and gag-driven adventure series based on the titular character, an arrogant and mischievous yet kind-hearted teenage hedgehog with the power to move at supersonic speeds. Sonic, with his idolizing young friend Tails, regularly oppose the wicked Dr. Ivo Robotnik, his robot henchmen Scratch, Grounder and Coconuts, and thwart their plans to conquer their home planet of Mobius.
Robotnik fools Captain Rescue into capturing Sonic after the aging superhero lets his guard down, so Tails must convince Rescue to be his old self again in order to save Sonic.
An asteroid is heading for Turtle Town and Robotnik offers to save it, but only if Sonic agrees to play in the Robolympics against him and his robots.
When Sonic saves a female hedgehog named Breezie, he falls in love. Sonic does not know that Breezie is a robot that Dr. Robotnik created to keep Sonic occupied while he floods a village near his fortress.
Sonic and Tails escape underground from Scratch and Grounder, but they are held captive there by a miserly mole named Spelunk.
Grounder accidentally puts a "genius chip" in his head and it makes him so smart that he easily captures Sonic and even takes over Robotnik's operations.
Sonic and Tails infiltrate Robotnik's new Casino Night Zone to stop him and his henchmen from scamming a group of sheep into becoming Robotnik's slaves.
