Luigi and Bowser fall in love, but Mario won't allow it

An Alternate universe where Luigi and Bowser are soulmates. Soulmate marks would always appear on someone of the same species. Mixed marks were not natural. The marks, whether it was their name, first words, or even a symbol, were never given to those of separate species. ~~~ I haven't seen any soulmate Au fics of these two, and I wanted to give it a shot at writing one. -- This was Posted on A03 first(not done), If you want to see it faster take a look on there -- Fic Cover art by @cousineggplant on twitter

I made my own cover art! **The placeholder cover was made by @arielries on tumblr** Mario and Luigi, the brothers in red and green. After Mario saves Princess Peach from Bowser's grasp again, something in Luigi wonders if the Koopa king really is as evil as the Mushroom kingdom, and his own brother, make him out to be. This is my first fanfic, so I hope it is somewhat decent! Updates may be sporadic because I am starting my first semester of college. I would like to note that some aspects of canon will be applied, and others, like height or age will be changed. Bonus points if you can find any of the references to songs or other literature! Feel free to DM or comment your guesses!

this story is basically just fluff. So if you don't want to feel that nice 'warming of the heart' sensation. Then this story isn't for you.

There are some things you don't know in the Mushroom kingdom, but when it comes to choice Mario picks a choice to change Luigi's life forever and spill his secrets

Luigi finds himself feeling a bit bored of the Mushroom Kingdom. He has a loving brother, who has kept his secret and even took a more protective role once Luigi came out to him. One day his boring life turned when Peach asked him to do his Duty to the Mushroom kingdom and simply talk to Bowser. He's never met bowser since he's never went on any adventure with his Brother. He soon finds himself with many questions, but most of all he find himself feeling more at home in the Koopa Kingdom then his home. Follow Luigi as he learns about the secret of all the other kingdoms. Watch as Luigi charms the hearts of multiple characters, soon finding himself in dangerous situations with blood splattering and magic blasting. Who is wanting Luigi dead and why ? Can Luigi uncover all the secrets his world has to offer. Or will he crumble under the pressure of if all ? Cover art is by @happyhorrorhare on Twitter, in my au luigi never went on any adventures with Mario. Never met bowser and never had daisy as a love interest. He's always known he's been different and didn't wanna play the manly man part. I've been reading up on some fanfics of this ship on my main account and decided to make a new account to write my own version because I love this ship so very much. I hope you enjoy reading as much as I enjoy writing it ~ Shadow

Luigi has slowly started to get fed up with everyone treating him like shit or acting like he doesn't exist. Though the last straw is finally pulled when his brother decides not to save him from Bowser and leaves him to 'rot' in Bowser's castle. While staying with Bowser, Luigi learns how to stand up for himself and gains a lot more confidence. He also ends up telling the gaint koopa why he strongly dislikes the mushroom kingdom and why he hates his brother and Peach. Upon hearing this Bowser offers the green plumber a chance to get revenge on everyone and everything that ever wronged him. Hey everyone! So this is mainly a villain arc story for Luigi meaning there will be a lot and I mean a lot of angst, I will put trigger warning at the beginning of those types of chapter when I get around to writing them. Now there will also be a bit of Bowuigi in this story mainly due to the fact I will be incuding the koopalings in the story so like they end up co parenting and falling in love like that. I don't know why but that whole concept seemed funny to me, so I decide to use it as like a way to take a break every now and again for the agnsty stuff. I don't own the characters or the artwork, just the story.

This takes place after the Super Mario Bros Movie (2023) Where Bowser was shrunk by a blue mushroom and put in a small jar, now living in Princess Peaches' castle for entirety: Watch as Luigi starts to notice how uncomfortable Bowser is in the tight, limited space and watch what he does for the enemy and villain to make his prison life more pleasurable. Luigi will face countless challenges such as convincing Mario, Peach and Toad that Bowser deserves a better prison life and the one he currently has is 'inhumane' along with convincing his brother everybody has kindness in their heart and deserves a second chance.
