Officer Kruller is an enemy ghost encountered in Luigi's Mansion 3. He is an obese police officer who resides in the Hotel Shops located on the third floor of the Last Resort. His battle is in his office. Luigi fights him for the second floor's elevator button.


When Luigi enters in the room where Officer Kruller was doing patrols, he is surprised at seeing Luigi and falls from the desk. He then puts his glasses on and goes through the bars to another room that has a box full of items. Officer Kruller grabs his main weapon, a water gun and prepares to attack Luigi with it. Since Officer Kruller is always on the other side of the room through the cell bars, Luigi is unable to battle him and so summons Gooigi to pass through the bars and start the battle with Officer Kruller (Gooigi can pass through bars with his metal body.). Kruller will use his sunglasses to prevent getting flashed as he bounces around the room.

In order to defeat him, Gooigi must vacuum Officer Kruller's sunglasses. However, when Gooigi tries to vacuum them from Officer Kruller when very close to him, Officer Kruller will be able to use his belly in the right moment to attack Gooigi. If Gooigi receives enough damage, he will be undone and Luigi will have to create him again to battle Officer Kruller. If Luigi fails to capture Officer Kruller, sometimes the next time he appears he will be comically portraying a pair of groucho glasses, although he can use another pair of his original sunglasses later on. After being defeated, Kruller struggles to not get vacuumed to no avail. After defeating Officer Kruller in two-player mode, Luigi, who was watching the battle from outside, takes all the credit saying that he did it, after which Gooigi humorously copies Luigi as he had actually defeated Officer Kruller.

At the end of the game, it is revealed that most ghosts in the hotel were brainwashed by King Boo, and thus were unwillling accomplices. Thus, this might also be true for Officer Kruller. However, his eventual fate remains unknown. 


While not a talkative type, Officer Kruller is clearly a coward, fleeing upon seeing Luigi and locking himself in the Security Office. He's also not a very good security guard, completely ignoring Luigi's ransacking - and likely looting - of the stores he's supposed to be watching.
