The Supervillain’s Guide to Being a Fat Kid follows new sixth grader, Max. Max is fat and on his first day of school becomes a target for school bully and eighth-grader Johnny “Pro.” Max’s mom is a single mother and his only friend Luca is poor and wears worn hand-me-downs. When Max gets fed up with being bullied, he decides to write to imprisoned supervillain, Master Plan for advice and help. Master Plan comes up with a step-by-step guide to stop Max from being bullied and elevate his social status — maybe even helping him get closer to the girl he likes. But when Max’s fortune starts to change, it threatens his friendship with Luca. Worse still, he realizes that supervillains rarely offer help without needing something in exchange.
