Faster than a speeding bullet! More powerful than a locomotive! Able to save the planet before 10 pm (9:30 on school nights)... It's Maximum Boy! It's April Fools! Over and over and over again... That's right, some evildoer is playing pranks across the entire country! There are whoopee cushions on school buses. Silly glasses on the faces of Mount Rushmore. This prankster is pulling off some pretty peculiar plots! But who better to put a stop to these childish stunts than our eleven-year old superhero? In fact, he's already got some suspects. Like Super Sid -- the all-too-perfect superhero that everyone loves to hate. Or could there be a new bully at the heart of all this mischief and mayhem? Maximum Boy is on the case!
