Summary
Mario sighs, shaking his head in mild exasperation “He’s a kid, yeah, but with an army, Lu. He’s dangerous.” Mario argued, already knowing his brother’s soft nature, especially when it came to children.
“He just wants his Papa back.” Luigi countered, shaking his head “Bowser seemed very…scared.” He said with a shrug.
“So, what? Are we supposed to let him keep terrorizing innocent people? If we let Bowser go, he’s just going to endanger all of us again. The villagers, the principessa, we can’t just—”
“I know, I know but—” He sighed through his nose, his frustration with himself only rising with knowing that his brother was right.
“I just— I never expected someone like him to care about anyone else, it changes the perspective a little, you know?”
(The one in which Luigi's softhearted nature gets him in trouble, but leads him to an unexpected treasure found within the walls of the Koopa Kingdom's Castle and within Bowser's heart.)

Summary
Sometimes one event changes everything. It started as just another princess-napping and ended with everything crashing down. In the aftermath, when the dust clears, all that's left is an odd sense of kinship. Luigi never dreamed he'd end up another parent figure for any of the Koopa King's sizeable brood, but by the time he realizes that's what's happening, it's too late to turn back. But does he even want to? The closer he gets to Bowser's kids, the fonder his opinion of the King becomes. He starts noticing things about the fire-breathing monarch he'd never knew to look for before.
Only one problem: Bowser and Mario have no idea.

Summary
The Koopa Kingdom's shaky peace with the Mushroom Kingdom is put in peril as King Boo invades and takes control of the Koopa Kingdom for himself. In a world where few look on his family with anything other than distain, Junior needs to find someone who can help get his family back. Luckily for him, a certain green plumber has plenty of experience with this sort of thing. (And a soft spot for a certain Koopa... but Junior doesn't need to know that.)

Summary
Luigi can’t live in Marios’ shadow while the toads of Toad Town continue to overlook him again and again forever. Realizing he needs a fresh start after some encouragement from his best fratello forever, Luigi sets off to find his own way. Finding a new town, a new job, and a new life for himself in the process. Everything goes well for Luigi, until boos suddenly start popping up left and right.
From moving on his own to a new town, fighting to keep it safe from pesky ghosts, and finding out his new home is right in the heart of Dark Land territory, what's a poor guy gotta do to catch a break? More importantly, should Luigi be worried about Bowser? Was he even important enough for a king to notice?
For once in his life, Luigi certainly hopes not.

Summary
Bowser didn't really care much about the green mario brother, or at least that's what he thought until his presence or well the lack of it started making things way more unbearable than ever, now he has to discover why this Is happening while he also starts noticing just how important that green human really was(to him?!)
(Heyy, first of all thanks for reading, I'm really grateful, but I feel like you need to know something before you start reading l, first of all English is not my first language so I'm probably grammatically wrong in so many things and second, I am really new to this whole fanfic thing so the may act a little occ sometimes or this fanfic will simply not be as good as other ones, if you still want to read thank you)

Luigi and the Beast by DracotheDeathEatingCupcake

Summary
Luigi is a simple man who lives a simple life. Every day is the same as the last, with nothing ever happening that changes the status quo. While some may think his life is boring, Luigi enjoys it well enough, relishing in the simple monotony, not needing endless adventure and excitement to make his life have meaning.
Unfortunately, everything changes when he gets the news that his beloved brother, Mario, has been kidnapped by a fearsome beast in a far off kingdom that he’s never heard of before. To make matters worse, in his endeavor to save his brother, he ends up making a deal with the beast where he has to stay as a prisoner in his brother’s place. Will he be able to survive his captivity in the castle of a beastly king? Or will he find that maybe there is more to life than simplicity, and that sometimes the best things in life require a little risk?

Summary
A tale as old as time.
A story told a million times.
A legend that simply won't die.
Everyone knows the fable of a strong green-clad man falling for a monstrous dragon turtle.
Sure, there are different versions of this story.
More popular, older, French versions.
Even a few movies.
But this one's better.
Well, maybe not.
It is gay though.
And also concerns Bowser and Luigi. (A couple MADE for this story)
And a musical, everyone likes musicals.
