Dark Atomic Boo is a big Dark Boo which is stonger than other Dark Boos. They do not like the sun at all and if one bites you it will poison Mario for 3 turns. Even though he is strong it comes at a price. Dark Atomic Boo aren't that smart at all. They love to scare Toads and Koopas. They work for King Boo and sometimes they like to make Black Holes that lead to King Boo's home. They can also make HP for himself.
