King Boom Boo was a boss from Sonic Adventure 2. He was fought by Knuckles in the Death Chamber, and is king to all the ghosts in the ancient pyramid Eggman had occupied. While his ghostly minions would resort to jumping out of nowhere and scaring the **** out of you, King Boom Boo would attack Knuckles head-on in the eerie darkness of the temple. He would throw blue FIAHBAWLZ in his general direction and trying to gobble rad red up in his luminescent jaws. King Boom Boo hates the light, and will hide in a shadow whenever it shines on him. King Boom Boo later appeared again a few times in the Sonic X series, where he could talk(horribly) and command his ghostly minions. Overall King Boom Boo is different from other random bosses in the Sonic series by not being a random Eggman/Gun robot, and having a bit of personality. With his goofy laughs and appearance, he and his ghost pals made for quite the comical and creative enemies of (somewhat) equivalence to the Boos from the Super Mario series. Or maybe they were just annoying. Whatever.
