Big Boo



Big Boos are a sub-species of Boo. Usually they resemble and behave similar to normal Boos, except that they are larger.

Super Mario World
Big Boos first appeared in Super Mario World. In the game, Big Boos inhabited the various Ghost Houses located around Dinosaur Land. Curiously, although they are over ten times bigger than a normal Boo, Big Boos still have the same mannerisms of their smaller counterparts. Of course, this means that when looked at, a Big Boo will fade and hide behind its arms. However, if someone's back is turned, a Big Boo will attack him or her from behind.

In the game, Big Boos are much more difficult to pass than their smaller brethren. As such, Mario or Luigi usually have to use a trampoline to jump over these massive ghosts. However, if Mario or Luigi can get a running start, they can usually Spin Jump over a Big Boo. Additionally, if there is room, the brothers can use a cape to fly over a Big Boo or perform a sliding Cape Attack during descent to actually destroy the Big Boo. In the game, the ghost's proper name is "The Big Boo". additionally, one a blue Big Boo, is a hidden boss of the secret Donut Plains Ghost House. He could be defeated by throwing Grab Blocks at his face. He had two normal Boos accompany him in battle.

TV series
Big Boos appeared in two episodes of the Super Mario World animated series. In the episode "Ghosts 'R' Us", Yoshi, while exploring Wizardheimer's Haunted House, encounters a Big Boo and three regular Boos. Terrified of the Boos, Yoshi proceeds to run away in a panic as the four ghosts give chase. After running some time through Wizardheimer's Haunted House and losing the three regular Boos, Yoshi manages to trick the Big Boo into entering a vacant room. With the Big Boo apparently trapped in this room, Yoshi locks the door. Unfortunately, the Big Boo simply phases through the wall and resumes chasing Yoshi. Yoshi eventually escapes his Big Boo tormentor by fleeing into the basement of Wizardheimer's Haunted House.

In Super Mario World's final episode, "Mama Luigi", a Big Boo is seen acting as a guard to Neon Castle. Mario, Luigi and Yoshi easily sneak past this Big Boo guard by using a nearby Warp Tube, which led to the basement of Neon Castle.

Super Mario Adventures
An unnamed Big Boo was also featured prominently in the Super Mario Adventures comic by Nintendo Power. After being lured into a Ghost House, Mario and Luigi, after an encounter with several dozen Boos, encounter a Big Boo. Attempting to stare down this Big Boo and the swarm of Boos, Mario and Luigi become exhausted after hours of simply staring at the shy ghosts. Nearly collapsing of exhaustion, Mario spots a door and, dragging Luigi, dashes to it, with the Boos and Big Boos after him. Bursting through the door of the room Mario and Luigi just entered, the Big Boo and his Boo minions are surprised to see Mario dressed as a doctor, with Luigi as his nurse. Acting as a psychiatrist, Mario manages to learn that, as a child, this Big Boo was constantly bullied, which led to it's vicious behavior. After hearing this Big Boo's sad tale, Mario gives some helpful words of wisdom and advice. The Big Boo, having become a changed ghost through Mario's therapy, happily leads Mario out of the Ghost House and gratefully thanks him as Mario, Luigi and Yoshi take-off to Bowser's Castle. Another Big Boo was later seen among the attendees to Bowser's wedding to the brainwashed Princess Toadstool.

''Hotel Mario
In Hotel Mario, Big Boos, first appearing in Ludwig's Thump Castle Hotel, are powerful enemies, being about one-sixth the size of a hotel floor; Big Boos in this game attacked in a manner similar to the ones of Super Mario World, slowly floating towards Mario or Luigi when they look away, turning transparent when directly looked at.

Super Mario RPG: Legend of the Seven Stars
One Big Boo has a cameo appearance in this game - it is used in Bowser's Terrorize attack. The enemy, The Big Boo, is just a misnamed regular Boo.

Super Mario 64
Big Boos return in the game Super Mario 64. Again, a Big Boo would disappear when looked at, and become visible again when Mario turns away. Big Boos can only be attacked when visible, so Mario had to attack these massive ghosts by either Ground Pounding them from above or punching them from the side. Regular Boos first appear in the courtyard of Princess Peach's Castle, and act the same way except less aggressive and requiring only one hit. One Boo is the keeper of Big Boo's Haunt, a miniature ghost house that shrinks the one who enters. Inside the ghost house, Mario can fight three more Big Boos. These Big Boos take three hits to defeat, becoming smaller after each hit. After destroying a Big Boo, Mario will receive a Power Star. In the Japanese version, the giant Boos are known as "Boss Teresa" rather than "Atomic Boo" (Big Boo's Japanese name). The giant Boo that appears when all the ghost house Boos are defeated is referred to is also known as "Master Teresa."

In the DS remake, Super Mario 64 DS, the leader of the Boos himself makes an appearance. In this game, King Boo has his trademark crown from later appearances and characteristic cackle. However, in game, he is erroneously referred to as Big Boo in English versions.

Other Games
In the Mario Party series, Big Boo makes a few appeareances. In Mario Party 2 a Big Boo appears in the Horror Land stage. As a typical Boo, it is able to steal objects from player's rivals, being coins or stars. However, Big Boo will deal for stealing the coins or the stars from all the opponents, while paying to him three times the amount of coins than a normal Boo would do. Characters can ask for him only in nightime; in daytime, Big Boo appears as a giant Boo statue. In Mario Party 4, Big Boo reapperas in the board Boo's Haunted Bash. In the game, it appears in an odd blue color.

Big Boo is an opponent in the Boxing game for Game & Watch Gallery 4. He is Luigi's second opponent. However, instead of boxing gloves, Big Boo uses smaller Boos to pummel his opponents.

Big Boos also appear in Super Princess Peach, which also introduces a new Big Boos subspecies, the Mad Big Boo. A Mad Big Boo is a Big Boo powered-up by the Rage Vibe. Mad Big Boos are stronger and faster than regular Big Boos and work under opposite mechanics (they shy away when not looked at but charge when faced).

Big Boos have appeared in Paper Mario: The Thousand-Year Door and Super Paper Mario as a rare enemy. In the former, it is an optional boss. Rather than being called Big Boos, however, they are known as Atomic Boos, which is closer to their Japanese name (Atomic Teresa). In these games, it is confirmed that Big Boos / Atomic Boos may be larger because they are several Boo spirits combined. For more information on these appearances, see Atomic Boo.
