Robotnik’s Rival is episode 36 of Adventures of Sonic the Hedgehog in production order (production code 238-136), the order used by the DVDs, WildBrain’s official uploads and our episode guide. It was the 19th episode to air in the 1993 syndicated run, on 30 September 1993. It was written by Gordon Bressack and directed by Kent Butterworth.
Synopsis
Robotnik is chasing Sonic and Tails across the countryside in a tank when a second tank opens fire on his. The two war machines knock each other out, and out of the other climbs Dr. Brandon Quark, a small red-haired scientist with duck feet from an old lab accident and his own plans for world domination.
The two villains trade insults – Robotnik insists on calling him “Quack” – and compare henchmen: Scratch and Grounder against Quark’s shape-shifting robot, D.U.F.U.S. Eventually they agree to join forces and capture Sonic together.
Working as a team is not in either man’s nature. Sonic knows it, and once captured he simply plays one genius off against the other until their rivalry blows the partnership apart – and sets him free.
Key Moments
