Captain Underpants and the Revolting Revenge of the Radioactive Robo-Boxers is the tenth book in the Captain Underpants series created by Dav Pilkey. It was published on January 15, 2013.
Plot
The giant zombie nerds move really slowly so the giant Zombie Nerd Harold actually crushed a giant ketchup packet. Tippy Tinkletrousers travels back to 10 minutes BEFORE Kipper and friends; they freeze upon seeing him. Tippy shrinks and abducts his past self to when George and Harold are about to be arrested. The boys travel back with their pets, but accidentally take Mr. Krupp with them. Big Tippy sends his smaller self back ten minutes to find where, then back there then, where the small ones zap themselves back and steal the Goosy-Grow 4000, which turns Tiny Tippy extremely massive. When Big Tippy attempts to use his nuclear bomb to kill Captain Underpants, Supa Mega Tippy zaps himself back in time (with his twin) and kicks Big Tippy and his bomb away into the Gulf of Mexico. When the bomb explodes, it blows a huge crater and kills the dinosaurs.
The five protagonists and their captor then travel to the African savannas where the boys and their pets gain the trust of some cavemen who inhabit the surrounding jungles. The cavemen are taught English through drawings and subsequently, the boys make the world's first comic book (which involves drawings of traps working on Tippy). The Neanderthals, inspired by the book, then set traps for Tippy and defeat him. He then sets off his freeze ray (which has been tampered with by his younger twin so that it could not be turned off), and the Goosy-Grow 4000 enlarges the ice which appears to make Crackers's condition deteriorate and causes the Ice Age (and freezing Tippy himself)
George and Harold are then transported to the future by Slightly Younger Tiny Tippy, who is now gigantic, thanks to the Goosy-Grow 4000. But it turns out they are now teachers (the mean and cruel ones they are used to be) and Mr. Krupp is an old man. After getting rid of their evil future selves by vowing never to take life seriously, they snap their fingers, turning both Mr. Krupps into Captain Underpants, and they beat up Slightly Younger Tiny Tippy, who afterwards attempts to use his nuclear bomb to blow up the entire galaxy. After that, Crackers and Sulu decide to save the entire galaxy by sending Slightly Younger Tiny Tippy and themselves back to the time before the universe existed (13.7 billion years ago). The three are then destroyed by Slightly Younger Tiny Tippy's giant nuclear bomb and the universe is formed. It also turns out that Crackers had laid a brood of eggs (revealing Crackers to have been a female.) and George, Harold and the younger Captain Underpants all decide to take care of them. Suddenly, George's and Harold's nemesis, Melvin Sneedly, in a giant Robo-Squid called the "Super Squid", appears and captures George, Harold, Captain Underpants, and Crackers's eggs, taking them back to the future.
