Atomic Boo is a Boo made up of hundreds of different Boos. Atomic Boo is an optional fight in Paper Mario: The Thousand-Year Door. When a bunch of Boos attacked and clung onto Mario in Creepy Steeple, Mario knocked them away with his Super Hammer, which angered the Boos. They then combined together to attack him. Atomic Boo attacks by flinging Boos at Mario, charging up a spook attack, and hitting Mario with status ailments. Once Atomic Boo was defeated, he would relinquish his Lucky Start badge to Mario.

Atomic Boo is similar to Boolossus from the game Luigi's Mansion.

And, when he attacks, we might get so scared that we get confused or can't move. I sure wouldn't want to see this thing standing behind me in the middle of the night... Creeeeeepy...
