Super Robotnik

Super Robotnik is Dr. Robotnik's super transformation and alter ego superhero.

History
Whilst cleaning up Dr Robotnik's lab, Coconuts accidentally knocks a bunch of chemicals into a bathtub. When Robotnik enters the lab, he slips on a mop and lands head first into the tub. The chemical formula end up giving him superhuman abilities, turning him into Super Robotnik, in a manner parodying most superheroes like Superman. His abilities include flight, super strength, x-ray vision, freeze breath, a super-computing brain, a telescopic eye, and heat vision. With these powers he humiliates Sonic and kidnaps Mobius's world leaders. He challenges Sonic to a gladiator contest where he, if he loses, must leave Mobius forever.

However, Robotnik soon learns that he is vulnerable in his caboose due to it not being soaked in the formula. When Sonic and Tails discover this, they get Professor Von Shlimmer to invent a powder which penetrates him through his weak spot and makes him weak. Whilst initially ineffective, Sonic is soon able to give Robotnik a kick in the bottom and into some disgusting yuck, causing him to lose his super powers.
