Hymie's creator, KAOS scientist Dr. Ratton, creates a super robot named Groppo for the soul purpose of destroying Hymie. However, Max, who managed to infiltrate KAOS headquarters, manages to temporarily halt the super robot by stealing his remote control. However, after some modifications, Groppo comes back under KAOS' control and after killing his creator goes on the hunt for Hymie. However, Hymie wants to make friends with Groppo instead of fighting the giant. Max, along with Dr. Harris and agent 42 decide to confront the giant robot. Unfortunately, none of the weapons they use are able to destroy him. Will Hymie change his attitude and fight Groppo and if he does will he be able to destroy him before Groppo destroys him?
