Feb 03, 2026

Introduce your young reader to the baddest bunch of do-gooders in town — Mr. Wolf, Mr. Piranha, Mr. Snake, and Mr. Shark, the main characters in bestselling author and illustrator Aaron Blabey's The Bad Guys graphic chapter book series.

Whether it’s a chain-saw monster confronting a velociraptor who has eaten an elderly piranha, or saving the world from Dr. Marmalade's meowing monsters, these unforgettable "bad guys" will entice readers of all ages and make everyone in the family cry from the laughter and hilarity. (We speak from experience.)  

If your young reader is new to this best-selling series, then the best place to start is, of course, Bad Guys #1: The Bad Guys. In this hilarious first installment, we meet Mr. Wolf, Mr. Snake, Mr. Piranha, and Mr. Shark as they plot to break 200 dogs out of the Maximum Security City Dog Pound. Author and illustrator Aaron Blabey is said to have started the series for his then 6-year-old son, who hated reading. In response, Blabey wrote something wildly fun – launching the series and inspiring readers and fans around the world to fall in love with his characters and reading itself.  

Almost a decade after the first book, the final installment, The Bad Guys #20: One Last Thing, brings the beloved series to an epic conclusion. Will these guys fail hard at trying to be good up until the very end? Start the side-splitting, sweet, and suspenseful series today to find out.
