Villain Overview

Ghosts...don't...die! Heh heh heh! Can you get out of here...ALIVE?
~ The Boos in Super Mario 64.

The Boos are an antagonistic group of nasty ghost-like creatures that are seen a lot in the Super Mario Bros. series and they are also the secondary antagonists of the Luigi's Mansion series.

Their main method of attack is to attack Mario only while his back is turned. If Mario looks at them they freeze and turn invisible and do not move at all until he turns his back to them again.

The most powerful and most clever Boo among them is their vile ruler, King Boo. The second most powerful of Boos are the Big Boos.

They are voiced by Sanae Suzaki.

Biography

Super Mario Bros 3.

Boos appear and are called Boo Diddlys, being a reference to Bo Diddly. However, they are called Boos after this game. Boos will shield their face if Mario or Luigi look at them, but will chase Mario/Luigi if they turn around. They can only be defeated with a Hammer Suit, Kooopa Shell or Star. The game also has Stretchs.

Super Mario World

In this game, the Boos are called Boo Buddies. These Boos act almost the same, except they go slower. Other variations are also in the game, including Big Boos, Boo Buddy Blocks, Boo Buddies Snakes, Boo Buddies Crews, Disappearing Boo Buddies and Eeries.

Super Mario Land 2: 6 Golden Coins

Boos appear in the Pumpkin Zone. A thrown green shell defeats them.

Other Media

Yakuman DS

Boos appear as opponents in the Japan only Mahjong game. They have a three star difficulty and think on a skillful way to win.

Tetris DS

Boos appear as items in multiplayer mode. When activated, the opponents cannot see their upcoming blocks.

Paper Mario

Paper Mario 64

Boos appear as friendly NPCs in the game. White Boos live in Boo's Mansion located in the Forever Forest while yellow Boos live at Gusty Gulch. The Boos in Boo's Mansion capture Skolar, the third Star Spirit, and refuse to surrender him until Mario approves Lady Bow's assignment to free the Boo's from Gusty Gulch from the tyranny of Tubba Blubba.

Paper Mario: The Thousand-Year Door

Boos appear in the Creepy Steeple and levels 21-29 of the Pit of 100 Trials. In the Steeple, a single Boo is in the middle of the room and says he misses his friends. In another room, when Mario opens a chest, 200 Boos fly out. The last Boo asks Mario how many Boos came out of the chest. If correct, he gives Mario an Ultra Shroom, or a single coin if wrong. When returning to the first Boo, he asks Mario if he will be mean to him. If Mario answers no, the Boo doesn't believe him and summons a horde of Boos that fly around the room towards Mario, slowly spinning towards him. If they get too close, they will carry him out of the Steeple. But if Mario repels the swarm with Spin Attacks, the Boos combine together to form Atomic Boo. Defeating the menace awards Mario with the Lucky Start badge. Boos will then appear as normal enemies.

Later on in the game, the Boo sends Mario an e-mail thanking him for freeing his friends, even though they attacked him. He reveals there were still several secrets in the Steeple.

Super Paper Mario

Boos return as enemies. They chase the player if they are not looking at them and hide if they do. They can be defeated by approaching them from the back. In the Flipside Arcade, one of the minigames is "Mansion Patrol", a shooter where the player has to shoot Boos, losing a life if they get too close to the screen.

Paper Mario: Sticker Star

Boos appear in World 4-3: The Enigmansion. They were sealed away within the Book of Sealing by a great ghost hunter in the past until Kamek undid the curse and released the Boos. Mario has to fight against a hundred Boos, including eighty-two that were stuck together. Once Mario captures all the Boos, Kamek undoes it again and Boos combine into Big Boo, but Mario defeats it and seals them away again.

Paper Mario: Color Splash

Boos appear in the parallel universes of Vortex Island, Lighthouse Island, and Fortune Island. In battle, other than hitting Mario, they can disappear, causing all attacks to miss until they reappear.

Paper Mario: The Origami King

Origimi Boos appear in the Scorching Sandpaper Desert, but only during the night before Mario defeats Hole Punch. In battle, they disappear before Mario alters the rings, forcing the player to memorize their positions. However, they will reveal themselves before times run out. Larger Paper Macho Boos can be fought in the overworld. They stop moving when Mario looks at them, and will teleport elsewhere if looked at too much. Mario has to navigate to the back of the Paper Macho Boo to hammer the Olly sticker to damage them. On Scuffle Island, a Paper Macho Boo is fought as the fourth opponent under the title Ghostly Goliath.

Super Smash Bros.

Super Smash Bros. Melee

A Boo appears as collectible trophy.

Super Smash Bros. Brawl

A Boo returns as a trophy and a sticker from Mario Tennis, increasing any fighter's throws by fourteen points. Boos also appear in the Luigi's Mansion stage, flying out of the mansion when a portion of the mansion is destroyed.

Super Smash Bros. for Nintendo 3DS/Super Smash Bros. for Wii U

Boos reprise their roles in both versions as a trophy and in the Luigi's Mansion stage. In Smash Tour on the Wii U version, the Boo trophy can be used for the fighter to start a match invisible.

Super Smash Bros. Ultimate

Alongside returning with the Luigi's Mansion stage, a Boo appears as a novice neutral primary spirit. In "World of Light", it can be found in Dracula's Castle of the Dark Realm. Its spirit battle is against a gray Kirby who can temporarily go invisible on the Mushroom Kingdom U stage. At level ninety-nine, Boo can then be enhanced to King Boo, who slows the falls of jumping fighters.

Dr. Mario World

A Boo can be acquired as an assistant. Its stage mode ability fills the skill meter by 10-50% when yellow viruses are eliminated. Its versus mode ability speeds up both the player and opponent's skill meters by 20-40%. A doctor Boo named Dr. Boo was added later to the game. He has a very fast skill meter recharge speed, but can only deal level one bombs. His stage mode ability eliminates all objects in a random 2x2 area. His verses mode ability eliminates any object in a single random spot of the area.

Mario + Rabbids Kingdom Battle

Boos may appear on certain stages as obstacles, warping around during turn transitions of the hero and enemy teams. If a Boo touches a character good or bad, it warps them to another spot of the battlefield. Additionally, the Boo Basher, one of Rabbit Mario's Melee weapons is based on a Boo.

Minecraft

In the "Super Mario Mash-Up Pack", Boos replace the Ghast Mobs.

Monopoly Gamer

Boo is a playable character, sold separately as a "Power Pack" figure.

The Legend of Zelda: Link's Awakening

Boos only appear in the dark room of the Bottle Grotto where the Power Bracelet can be found. Unlike other Boos, they do not hide when Link looks at them, and teleport elsewhere in the room when struck at with the sword. They can only be defeated when Link uses Magic Powder on one of the torches in the room, making them vulnerable.

Trivia

  • Boo's Mario Strikers Charged Football outfits resemble the Spooky Speedster's outfit.
  • The manual for Mario Kart DS refers to the item Boo as "Boo Hoo".
  • Creator Shigeru Miyamoto got the idea for Boo from the wife of his coworker and close friend Takashi Tezuka, as she is shy but one day got very angry at him for coming home late from work.
  • In both Super Mario 64 and Luigi's Mansion, Boo's old laugh is just a sped up version of Bowser's laugh from Super Mario 64 with echoes added. It was also reused in Mario Tennis 64 as well as the Nintendo DS remake of Super Mario 64, the Nintendo 3DS remake of Luigi's Mansion and in the first seven Mario Party games.
  • Strangely, in Mario Golf: Toadstool Tour, Boo hits right-handed, but in the Mario Baseball series, it hits left-handed.
  • In the Animal Crossing games, a character named Wisp appears, who bears a resemblance to Boo. The main difference is the facial appearance and headgear.
  • In Super Mario Sunshine, the Boos are the only Boos that can be defeated by jumping on them outside of the Mario RPG titles.
  • Mumbies, enemies from the Kirby series, attack in an identical way to Boos.
  • The Boos' very own name is also shared by a group of fellow ghostly enemies called Boom Boos (also called "Booms") ruled by their leader King Boom Boo from Sonic Adventure 2.
  • According to Professor E. Gadd in Luigi's Mansion, Boos grow in power when they are together.
