When their alien spaceship lands on the roof of Jerome Horwitz Elementary School, Zorx, Klax, and Jennifer plan to take over the Earth, using school children as their zombie nerd henchmen.

When three aliens bent on world domination, land on Jerome Horwitz Elementary school-disguising themselves as cafeteria ladies in order to turn the children into zombie nerds-it's clearly a job for Captain Underpants!

Fourth graders George Beard and Harold Hutchins invent the wedgie-powered superhero Captain Underpants in the first book in this #1 New York Times bestselling series by Dav Pilkey, the author and illustrator of Dog Man! George and Harold are a couple of class clowns. The only thing they enjoy more than playing practical jokes is creating their own comic books. And together they've created the greatest superhero in the history of their elementary school: Captain Underpants! His true identity is SO secret, even HE doesn't know who he is!

Only Captain Underpants can stop the three evil space aliens who have invaded Jerome Horwitz Elementary School and turned everyone into lunchroom zombie nerds.
