This is a Luigi's Mansion AU where king boo is a girl and kidnapped Mario for a different reason. And I wanted to make a gender swap story without a super crown form and make an AU for once. In this king boo is queen boo instead and her reasoning for doing some of the stuff she does is different. Some characters maybe really different and others may just not exist.

Ghosts are fascinating. However, what if a spirit floated in front of you? Would you faint? Definitely. You always get so nervous around them. You got a far too mysterious job, went there to see the new place and met an old scientist, called E. Gadd, who showed you everything you needed to know. He was your caring, but also hyperactive and crazy, boss. Although dealing with the captured entities -Boos to be exact- wasn't easy at first, you managed to get used to it. However... there was something bothering you. The Boos cackled the whole time about their great king, two stupid plumbers and the annoying professor. You are too curious and stubborn to ignore the round specters. You'll find out what's going on. If it's the last thing you do. ---------------------------------------------------------------------------------------------- (Cover: Art by me) Start: May 14, 2019 End: ??? Hello there! Nice you got here ;) Well as you can see, this is a King Boo x Reader story. My favourite Mario character is King Boo so here you go. Also a shoutout to all King Boo storys, which gave me the motivation to write this (This includes King Boo x Reader, Luigi x King Boo, King Boo x OCs or even Princess Peach x King Boo). Enjoy reading!

An AU where Luigi and King Boo fuses together as one and they have to learn how to live with their new life.

(This takes place in luigi's mansion 3 so spoilers if you haven't finished the game or played it yet) You, mario, polterpup, the toads, luigi, and finally peach are all going to this fancy hotel because you all been invited to go. But all the other have been captured including luigi! Will you save your friends or join king boo?

A fanfiction about Luigi and King Boo falling in love. (Not part of my "Please Luigi" series or "Reversed Mansion".) Luigi has won a free vacation to the Last Resort by Helen Gravely. He brought Mario, Peach, and 3 Toads with him. Oh, and Polterpup, too. Time skipping to where Luigi wakes up from Peach's screaming. He tried to find Peach and his brother in their rooms, but no one was there. Helen came out of the elevator and showed Luigi what she has done to his friends and brother. Helen was about to trap Luigi into the painting, but Luigi ran for his life. He went down the laundry chute. (I think that's how you spell it idk.) He was woken up by Polterpup licking his face. Luigi got up and wandered around, looking for a Plotergeist. But while he was in the laundry room, he found his old pal, King Boo. But instead of trying to capture him, King Boo was willing to help Luigi. Luigi was confused, but they both felt something for each other... (Really long description, but that's where the story continues...) (Also, it's taken place in Luigi's Mansion 3) Edit: #1 for luigixkingboo (10/2/2020)
