Doc is great, Doc is all. Doc not leave cave.
Robosuitcase is a robot built by Doc. He appears as the first boss in the video game, Tonic Trouble.
Robosuitcase malfunctioned and locked Doc inside his cave, thinking he was protecting him. He tried to kill Ed with a stick as Ed made his way to rescue the Doc, but Ed tricked him into standing on a switch that revealed a popcorn machine. Ed ate some of the Doc's popcorn to transform into his alter ego, Super Ed. By hitting him three times, Super Ed defeated Robosuitcase, and took his first weapon, the Stick, from his corpse.
