|“||That scaredy-cat Luigi has made it this far... Oh, we're so frightened! I guess it's our turn, then... All right, Boos, let's assume our real form... But first, how about giving him a little scare!||„|
|~ Boolossus preparing to battle Luigi.|
Boolossus, also known as the "Jumbo Ghost", is the secondary antagonist of the video game Luigi's Mansion, and a minor antagonist in Luigi's Mansion 3. It is a gargantuan Boo composed of fifteen smaller Boos, serving as the third boss of the first game.
Boolossus first appeared in Luigi's Mansion. One of the most powerful ghosts in King Boo's army, he was caught by Professer E. Gadd who stuffed his essence into a painting, along with many other ghosts of the mansion. This resulted in King Boo attacking E. Gadd's lab out of anger. During his assault, King Boo rescued Boolossus and ordered the rest of the Boos to free the rest of E. Gadd's portrait ghosts in the mansion. Once freed, King Boo creates a large mansion within the span of a single night just outside E. Gadd's lab, where the rest of the portrait ghosts and Boolossus reside. Boolossus waits on the large balcony on the third floor of the mansion. If Luigi attempts to access the balcony with less than twenty Boos captured, he will be sent back to the foyer by Boolossus until he captures at least twenty Boos.
Once Luigi reaches the balcony, he will find Boolossus' squadron together in a circle awaiting his arrival. Together, the Boos surround and frighten Luigi by enclosing their circle around him. With Luigi in their grasp, the Boos teleport him to a dimensional version of the balcony and combine their strength to become Boolossus. Boolossus is at first a massive and slow Boo that tries to crush Luigi by bouncing on him. Luigi must force Boolossus to touch the horn of one of the two unicorn ice sculptures to break him into the smaller Boos. Luigi use an Ice Elemental Ghost to freeze the Boos in ice and suck them up. After a while, the Boos will form Booslossus again. He grows smaller and faster as more Boos are defeated, and the Boos are more hasty to avoid the ice beams. Once he and his 14 minions are sucked up (each one has 1 hit point), Boolossus is defeated. His soul is then turned into a painting.
Luigi's Mansion 3
In Luigi's Mansion 3, Boolossus returns as the final boss of Scarescraper Mode, facing off with the player and their team once they reach the final floor. He has similar abilities to King Boo but is much larger is unable to multiply himself aside from being split apart to smaller Boos. All the smaller Boos must be defeated in order to win the battle against Boolossus.
- Boolossus' name is a portmanteau of "Boo" and "Colossus", probably due to his massive size.
- The name "Boolossus" also literally translates to "Giant Boo".
- Jalhalla from the Zelda series is similar to him in terms of weaknesses.
- Boolossus appears in the Mario UNO cards on the "Draw 4" card.
- In the PAL version of Luigi's Mansion, Luigi rides around on top of the Poltergust 3000 during the Boolossus battle within the Hidden Mansion. This provides faster transportation, but also less traction. However, this does not happen in any version of the Nintendo 3DS edition.
- Boolossus is the only Portrait Ghost to not have HP.
- Along with King Boo, Boolossus is one of the two only Boos that are Portrait Ghosts.
- Oddly, Boolossus is Ghost #22 in the gallery even though he is the 16th ghost caught.
- Boolossus has other two names, "Jumbo Boo" ("Janbo Teresa" in Japanese) and "Buulussus" (in German and later translated to English).
- Boolossus bears a resemblance to Big Boo from Super Mario 64.
