Story[]
Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy, Part 2-The Revenge of the Ridiculous Robo-Boogers.[]
Upon switching back to his correct body, Melvin keeps Captain Underpants' superpowers, yet refuses to help Major Tomski and the other astronauts until George and Harold change the comic they made about him according to his demands. George and Harold, however, do not do this, and instead help Captain Underpants defeat the Robo-Boogers. However, when Ingrid Ashley shows up to the scene, Melvin arrives and claims credit for defeating the Robo-Boogers, even using his heat vision to burn a big 'BM' into the ground. Then, he declares that everyone will bear witness to the 'humiliating defeat of Captain Underpants' before repeatedly whipping him with a curtain, and demanding that the Captain bow down to him. Captain Underpants however, refuses to stand down, and just as well, because George and Harold use the Combine-O-Tron 2000 to restore Captain Underpants' superpowers, and erases the news crew's memories with the Forgetchamacallit 2000 (as well as the memories of everyone watching the story), while Melvin gets his comeuppance when an angry mob chases him into the sunset.
Captain Underpants and the Tyrannical Retaliation of the Turbo Toilet 2000[]
After imbuing himself with Captain Underpants' superpowers via DNA extracted from Mr. Krupp's toenail, Melvin defeats the Turbo Toilet 2000, and is revered the world over. The Mayor congratulates him on his success with a parade, Weird Al Yankovic writes a song about him, and the Vice President gives him a congratulatory letter. Melvin thus re-assumes his Big Melvin identity to help the citizens of Piqua, with everyone now only needing to yell 'Yo, Big Melvin!' to call upon him, whereupon Melvin will stop whatever he's doing, put on his cape, and go help whoever needs it. However, while Melvin finds this fun at first, the residents of Piqua soon start to call upon Melvin and interrupt his experiments for increasingly menial things. The final straw comes when Melvin is attempting to solve the mystery of everything, yet a woman calls upon him wondering if her pants make her look fat. After this, Melvin invents his Glow-In-The-Dark Time-Traveling Robo-Squid Suit and uses it, along with the GPS in Sulu's robotic endoskeleton, to bring George, Harold, and Captain Underpants back to the present to erase his superhero future.
TV Show[]
In 'The Taxing Trauma of the Treacherous Tattle Trials, Part 1 and 2', Melvinborg imbues Melvin with nanobots to ensure that he passes the Tattle Trials and gets into Eliteinati Academy. However, while things do work well at first, the Nanobots go rogue and take over Melvin. Captain Underpants is able to get them out of Melvin's system, but they then take over the dome, and later, Captain Underpants himself.
