This duplicate was extremely well behaved, so much that Hobbes couldn't believe that people thought he was actually Calvin. This, however, backfired on Calvin when the duplicate started writing valentines to Susie Derkins. When Calvin found out, he immediately began searching for the duplicate, trying valiantly to defend his reputation and principles as "Dictator-For-Life" of the Get Rid Of Slimy girlS club". Eventually, Calvin confronted the duplicate, and they got into a fight. The duplicate, however, vaporized when he had an evil thought, thanks to a Moral Compromise Spectral Release Phantasmatron Calvin unknowingly built into the Ethicator. When the duplicate explained that he was Calvin's good side, he frequently heard the comment "If that was true [he'd] be a lot smaller." After his evaporation, Hobbes admitted that Calvin was the only person he knew "whose good side was prone to badness."
