Fourth-grade class clowns George Beard and Harold Hutchins have created the greatest superhero in the history of their elementary school -- and now they're going to bring him to life! Meet Captain Underpants! His true identity is SO secret, even HE doesn't know who he is!

Harold and George's time-traveling Purple Potty lands them in an alternate universe where everything seems delightful, but evil lurks just beneath the surface, and leads to a battle between Captain Underpants and his own evil twin.

When a new sitter arrives and a movie star goes missing, Dog Man and Cat Kid investigate, but Petey, the world's most evil cat, complicates their case.

Dog Man, the newest hero from the creator of Captain Underpants, is still learning a few tricks of the trade. If only the Chief would throw him a bone every once and a while...Dog Man needs to dry up the drool, dust away the dander, and roll out of the refuse if he's going to impress the Chief, and he needs to do it fast! Petey the cat is out of the bag, and his criminal curiosity is taking the city by storm. Can the canine crime biter unleash justice...

George and Harold are always good at using their imaginations, and that drives their mean homeroom teacher, Ms. Ribble, crazy! But this time, they've come up with much more than a silly prank they've accidentally created a MONSTER! With her horrendous hairdo and two rabid robots, Wedgie Woman is well on her way to world domination, and only the Waistband Warrior can stop her!

When a new bunch of baddies bust up the town, Dog Man is called into action -- and this time he isn't alone. With a cute kitten and a remarkable robot by his side, our heroes must save the day by joining forces with an unlikely ally: Petey, the World's Most Evil Cat. But can the villainous Petey avoid vengeance and venture into virtue?
