When Michael G (yes, "G" is his whole last name, and that's why everyone calls him G-Man) has to keep a journal in Mrs. Rosario's class at school, naturally he writes about his ambition to have superpowers and join the superheroes of his city (like Captain Thunderman) in the fight for justice. After all, his friend Billy Demon just got an awesome winged flying suit and superpowers of his own, and now he's the most popular kid in school! Mikey would just love to have superpowers too, but how will he get them? And if he does get them, what will he do with them?
