| ~ Knuckles's reaction upon encountering King Boom Boo. |
King Boom Boo (in Japanese: キングブーブ, Kingubūbu?), also known as the "King Of Ghosts", is a minor antagonist in the video game Sonic Adventure 2, and in the anime Sonic X. He is a giant ghostly beast who rules a legion of spectral monsters known as Boom Boos (also called "Boos").
He resides in the Death Chamber level, yet his presence is felt at the giant pillars of the Pumpkin Hill level and Aquatic Mines level, and like other ghosts in the Sonic the Hedgehog universe, he is repelled by light.
Personality[]
King Boom Boo is malicious, sadistic and mischievous, laughing merrily when causing harm to others. However, he also has a cowardly side, as when the odds would turn against him during his battle with Knuckles, he would resort to running away. He also has a great aversion to sunlight and will try to hide from it. In the games, he appears incapable of coherent speech, only giving off babbles, grunts and roars.
Biography[]
Sonic Adventure 2[]
Knuckles encounters King Boom Boo while searching for keys to a door that Sonic, Tails, and Amy were trying to get through. In the boss battle, Knuckles runs around a circular arena while followed by King Boom Boo who throws blue fireballs at him (and may also attempt to bite him at close range). Occasionally, the ghost stops to spew a huge blue wave of flames, and during that time Knuckles must stun King Boom Boo by moving behind him and punching a Boo holding an hourglass, activating the hourglass which opens panels in the ceiling, making light fill the room. King Boom Boo then retreats into the ground. Knuckles must chase his shadow across the room and dig it up, then run after him and punch him. He can be damaged up to three times in one hourglass flip. If the player moves too fast when running from him, King Boom Boo will turn around and chase them from the other side. After four hits, King Boom Boo disperses into air.
Sonic Rivals 2[]
King Boom Boo is a collectible card that can be contained by winning the Tails Cup in Single Player. The card unlocks Tails' Captain suit.
Sonic Runners[]
King Boom Boo appears as a S Rare Fly Type buddy which gives a thirty percent chance of having the player's score boosted when defeating enemies.
In the Halloween event, King Boom Boo was fed a strange candy by Eggman and brainwashed into serving him as the guard of his Halloween theme park. Team Sonic intervened, but King Boom Boo got the best of them. After discovering the candy was neutralized by strong light, they use E-123 Omega's searchlight to return everyone brainwashed by the candy back to normal. King Boom Boo then proceeded to chase after Eggman in vengeance.

TailsTube[]
King Boom Boo's possible human self.
In TailsTube No. 9 (Scary Story Spooktacular), Tails tells a possible origin story for King Boom Boo.
Long ago, a human king accompanied by his loyal knights leads an expedition into a haunted pyramid in search of a mystical talisman that could grant eternal life, so long as an unknown price is paid in exchange. Driven by greed, the evil king plans to sacrifice his knights to pay such a price. As they traveled through the pyramid, his knights are dragged into darkness one by one to an unseen fate.
Once the king finally finds the talisman, he realizes that all of his knights are gone, but doesn't care. As he goes to take the amulet, his knights, who have all become ghosts, try to warn him of the price he must pay. Believing that he had already paid it with his soldiers' lives, the greedy king takes the talisman, but then dies soon after. Now the king's ghost, which was much bigger than the others, was doomed to haunt the pyramid along with his knights forever.
In other media[]
King Boom Boos and his legions of Boom Boos as seen in Sonic X comicbook series.
King Boom Boo appears alongside his minions in both the anime series Sonic X and the Sonic X comic book series by Archie Comics. Unlike most other elements from the Sonic Adventure series carried over to the Sonic X anime, Boom Boo doesn't share his game counterpart's role, inhabiting a haunted castle instead of Eggman's pyramid base.
King Boom Boo, along with his Boo/Boom Boo minions also made an appearance in Sonic the Comic Online, where he is only referred to as the "King of Ghosts".

Trivia[]
- King Boom Boo is the only boss in Sonic Adventure 2 to have green text appear on-screen before facing him, most likely because the color reflects his ghostly nature while all other bosses are either living creatures or technology-based.
- Although it was never shown, it is possible that Knuckles is phasmophobic (the fear of ghost), as when he notices King Boom Boo, he says "What the... a ghost?!", but he only says it with a little disbelief. However, in an unused line, Knuckles screams "What?! A ghost!" in a more frightened tone, and in the Japanese version, Knuckles says "O-Obake!", meaning "G-Ghost!", and he is clearly very scared, making Boom Boo one of the few things to actually scare Knuckles.
- King Boom Boo was suggested as a character for issues of the Sonic Archie Comics following "Sonic the Hedgehog #134", but the plot in which he was intended to feature was cut.
- King Boom Boo and the other ghosts in Death Chamber look similar to Hyudoro in Sandopolis Zone in Sonic & Knuckles. Also, both of them live in pyramids.
- There is a glitch in the boss fight when the windows on the roof of the arena are opened if the player pauses the game. The sky will change from blue to black. If the player resumes the game, the sky will return to its normal color. However, if the player restarts the game from the pause menu, the sky will stay black for the rest of the fight.
- Strangely, if the player restarts the battle, there will be a scene where a Boo lifting the Hourglass will appear, which does not appear before.
- During the Halloween update of Sonic Runners, King Boom Boo's name was incorrectly spelled as "King Boob Boo". Developers apologized for the issue and stated that they are fixing the issue in the future. Players have received this notification automatically if they have got the Halloween update. The name was most likely translated incorrectly from the character's Japanese name キングブーブ (Kingu Buubu), which the last word in the name reads more similarly to the incorrect word.
