Captain Underpants Wiki

Giant Evil Zombie Nerds are the byproduct of people drinking Super-Evil Zombie Nerd Juice


Captain Underpants and the Invasion of the Incredibly Naughty Cafeteria Ladies from Outer Space (and the Subsequent Assault of the Equally Evil Lunchroom Zombie Nerds)[]

Zorx, Klax, and Jennifer infiltrate Jerome Horwitz Elementary School as lunch ladies and serve the entire school Zombie Nerd Milkshakes with the Zombie Nerd Juice. They all obeyed the aliens' command and attacked George Beard, Harold Hutchins, and Captain Underpants. The three climbed up a latter to the school roof and escaped them. After, fighting the aliens and The Dandelion of Doom, they used Anti Zombie Nerd Juice to turn everyone back to normal.

Captain Underpants & The Terrifying Re-turn of Tippy Tinkletrousers[]

In an alternate reality where Tippy Tinkletrousers accidentally scared Kipper Krupp, which resulted in Mr. Krupp getting fired and not turning into Captain Underpants, the aliens successfully turned all the teachers and students into zombie nerds including George and Harold. They were later given Super Evil Rapid Growth Juice turning them giant but at some point they betrayed the aliens and likely killed them. When Tippy entered the alternate reality, Zombie Nerd Harold snuck up from behind and seemly crushed him. Luckily since Giant Zombie Nerds move slowly, Tippy was able to escape in his pants while replacing himself with a giant ketchup pack.
