A Boo's most common pattern of attack is to sneak up on the player (usually Mario) from behind while they are facing away from them; however, they stop their attack and hide behind their arms if looked at. Being ghosts, they are usually invincible, and unable to be defeated without certain items or conditions.
It has been implied that Boos may have been other living species before they became Boos, but this has not been made clear.
There are also sub-species of Boo based on other species; for example undead Shy Guys become "Boo Guys" while undead
Lakitus become "Fishin' Boo"s.

Takashi Tezuka had the idea of putting his wife in the game. According to Miyamoto, "(Tezuka's) wife is very quiet normally, but one day she exploded, maddened by all the time he spent at work.

Hitodama. They have faces featuring large
fangs and long
tongues, and three short extremities which resemble two arms and a tail. Being ghosts, Boos often appear in
haunted house-themed levels in the games, in which they'll "sneak up" on the player, much in the fashion of ghosts of popular culture. Their presence can be recognized by their signature
cackle. They are generally depicted as
bashful and
mischievous in nature.

Mario or
Luigi by sneaking up on them. Since their first appearance, apart from their names being shortened simply to "Boos", their design or habits have not changed significantly, despite their appearances in most games since ''Super Mario Bros. 3.'' They have, however, spawned a number of subspecies over the years, with the first being the "Stretch" that also debuted ''Super Mario Bros. 3''. Stretches are essentially Boos that are attached to platforms that will pop up to Mario or Luigi should they attempt to step on it.
Boos played a much more prominent role in ''

Lakitu, as well as the secret
boss "Big Boo", a larger and stronger Boo who would return as a boss throughout the series and even gain a subspecies of the same name. ''Super Mario World'' was also the first game to reveal that some Boos were able to transform into blocks, which, if lured into a suitable position, can be used to reach otherwise unreachable platforms. This trait later reappeared in ''
Yoshi's Story'' of the ''
Yoshi'' series and ''

In this game - unlike most preceding it - Boos could actually be killed by attacking them, by using moves such as a punch or ground pound.

IGN's Audrey Drake listed Boo as one of the best enemies in the ''Mario'' series while
GameDaily ranked Boo seventh in a similar list, saying it is "unique" due to the fact that "Mario cannot kill with a

his special suits." They also placed Boo fifth in a list of Nintendo characters that deserve their own games, calling it "Nintendo's favorite ghost". Boo was listed as the second best ghost in video game history by
Joystick Division. In a reader-based poll, it placed on top of best ghost characters in a Nintendo game, receiving four times as many votes as the
