Sonic Adventure 2
The Boos first appeared in
and its later iteration Sonic Adventure 2 . The can be found in the following Sonic Adventure 2: Battle Stages for each character:
A attack type Boo approaching
In this game, there are two types of Boo: ones with black eyes (normal types) and those with red and yellow eyes (attack types). Normal Boos are harmless and scurry along the ground, but will also hide in gravestones, pumpkins, and even just in the ground. When approached, these Boos will pop up in the playable character's face to feign an attack. This does not inflict damage, but can momentarily stun the playable character. After a while, the Boo will disappear, although the player will not earn any
Unlike normal Boos, attack type Boos can hurt the player like regular enemies. These Boos will float around normally until they spot the player and will start chasing them down. Should they reach the playable character, they will either hold them in place for other enemies to attack them, or attack directly. While just touching an attack type Boo will damage the player, defeating one will grant the player three hundred points.
Throwing objects at these enemies will not affect on them, and when defeated in battle, the Boos release neither

Sonic Lost World
. Sonic Lost World
Wii U version of , both the Boos and Sonic Lost World Boom Boos appear exclusively in Sky Road Zone 4. In the Zone, the Boos are indestructible obstacles that move left or right across the screen in long rows and cause damage when touched. The player has to avoid them using the Magenta Rhythm Color Power.
, Boos appear as a Rare Sonic Runners Power Type buddy which boosts score for destroying super enemies, and turn enemies into super enemies after reaching certain combo amounts.
During the "Halloween" event, the Boos were being brainwashed by
Dr. Eggman who fed them with special candy. A Boo thus aligned itself with Rouge the Bat and E-123 Omega to stop Eggman. When Team Sonic joined the mission, the Boo helped guide the team to Eggman hideout. In the showdown with Eggman and the enslaved King Boom Boo, the Boo then brought Omega a searchlight in accordance to Rouge's orders, which Omega used to restore King Boom Boo to normal.
Team Sonic Racing
, the Boos appear in Team Sonic Racing Boo's House. When racing along this track, the player can see them in the background, especially inside the track's signature long corridor with columns. Inside the corridor room in particular, the Boos will from time to time appear between two columns where they will jump upward. Afterward, they will disappear and create a pink wall of flames between their two columns which deals damage to all racers who pass through it.
Similar to their king, the Boos are mischievous and malicious, giggling whenever they cause misdeeds. While normal Boos are rather passive, attack type Boos are much more energetic.
Powers and abilities
The Boos have the ability to levitate and move through midair. As ghosts, they can turn themselves invisible and possess a spirit physiology that causes them to evaporate whenever they take too much damage while tangible.
Boom Boo is large variation of Boos who also first appears in . Boom Boos look identical to normal Boos, but are able to evaporate three times larger after taking damage or shrink down after being defeated and eventually become attack-type Boos.

They first appeared in " Sonic's Scream Test" where they accidentally released into the living world. However, Sonic and his allies were able to save their victims and reseal them.
The Boos would later return in the
to help King Boom Boo escape into the living world by possessing people. However, they were convinced to return to their eternal resting place.
Sonic X comics
Before Sonic Adventure 2, there have been similar ghosts enemies called Hyudoros, which act similarly like Boos and are featured inside the pyramid at the second act of Sandopolis Zone in . Despite these facts, both Boos/Boom Boos and Hyudoros can be consider as separated ghost species.
Sonic & Knuckles Boo shares its name with a similar from the Mario series, the same goes for ghost enemies Spiny.
