Superhero School: The Revenge of the Green Meanie by Alan MacDonald
From the bestselling author of Dirty Bertie. Stan Button had always dreamed of becoming a superhero. Then one day a letter arrives inviting him for an interview at the mysterious Mighty High School. To his amazement, Stan is offered a place - starting immediately. His superpower is `non-conventional', as are those of his two new best friends, but lessons in supervillain-spotting and tight-wearing mean they are soon ready to defeat the evil Green Meanie... who might just be none other than Professor Von Hardbum, a teacher at their school. Each adventure will be heavily illustrated throughout with fantastic art by Nigel Baines, for truly brilliant comic-book style fun.
