Jeff Dunham
Melvin wears a blue superhero costume, and is used to poke fun at superheroes. When asked about his superhuman powers, he indicates that he has X-ray vision, adding, "I love looking at boobies!" He appears to have no other powers, however: When Dunham asks how far he can fly, he responds, "How far can you throw me?", and when asked if he can stop a bullet like Superman, he responds, "Yeah. Once."  Dunham portrays Melvin as unimpressed with other superheroes: When told Superman can leap tall buildings in a single bound, Melvin dismisses him as a "showoff," arguing that he can simply walk around them, observes that Aquaman has the same powers as SpongeBob SquarePants, asserts that the Flash's super speed is derived from methamphetamine, that the Hulk's vaunted ability to get stronger as he gets angrier merely mirrors "every white trash guy on COPS," and makes innuendo about the questionable relationship between Batman and the underage Robin. Melvin's first onscreen appearance was in the July 2003 Comedy Central Presents episode, in which he had small, black, beady eyes. By his next appearance, in Spark of Insanity, he had been modified to have large, blue, crossed eyes. He also has an enormous nose, which he claims is his symbol, and whose similarity in shape to that of a penis is alluded to in the act. Dunham sculpted the current version of Melvin's head himself, and hired an effects company called Renegade Effects Groups to create the rubber mold and complete the puppet, before then installing the mechanics himself.
