Summary
If anything, Larry Koopa is loyal.
Loyal to Bowser. Loyal to his kingdom. Loyal to his siblings, who he's always had even when he's had nothing else. When war beckons, Larry doesn't care that he's barely fifteen. The objective of war, after all, is simple: destroy the other side.
But things get complicated when Bowser begins keeping secrets and invites a power that costs his kingdom everything.
Taken prisoner by the Mushroom Kingdom, Larry is forced to strike a deal he plans to go back on the first opportunity he gets. Plans, however, have a funny way of changing before one realizes.
Mario is is no hurry to trust Larry, or the far-fetched story he tells about the tyrannical usurper to Bowser's throne. But Princess Peach is in danger, and as soon as his friend is safe, he'll ensure that Larry answers for his crimes.
In the clutches of the usurper, Lemmy Koopa watches his kingdom crumble as a hostage. Escape is his only hope, and just might be possible, with the help of a certain princess who hates his guts.
The odds are stacked against him, but Larry will die fighting for his family and home, if that's what it takes.

Summary
Part 2 of the vivor series! We have many new characters, yet surprisingly less fandoms. I suppose that can be attributed to the immense amount of Mario, Kirby and Dont Starve characters. Slightly more serious than season 1.

Summary
With 1-Up Mushrooms completely extinct, many kingdoms find themselves on the brink of collapse. Bowser seizes the opportunity to invade and take total control of the entire Mushroom World, installing his Military to serve as the governing bodies of the overthrown kingdoms. 3 years later, Mr. L finds himself in what was formerly New Donk City, now branded Wario City, where many displaced residents of occupied kingdoms found themselves.
With Mario’s status unknown, Mr. L has spent the 3 grueling years fighting in the shadows. As Darkland’s most wanted, he feels he would be most safe to practice his vigilante justice in the occupied Kongo Bongo capital on their thin slice of the mainland. When he is encountered by some old friends in an altercation in a dark alley, he has no option but to begrudgingly help them in their mission to take back the Mushroom World, without the help of Super Mario.

Summary
To set foot in Bowser’s Castle means playing a deadly game.
The rules are simple: respect the royals, but never draw their notice.
You have no choice but to follow your traveling troupe to the castle. It’s just one night, you tell yourself as you rehearse, just one performance for one royal ball. The pay will cover a year’s worth of rent for your struggling family.
But just like a dance, one wrong step will ruin everything, and might even catch the eye of the most dangerous royal of all: Crown Prince Ludwig von Koopa himself.
From the very moment you stepped into the ballroom, you had unwittingly fallen into his web.
And just like a spider, now that he has you, he will never let you go.

Summary
There exists a point in time where the crossroads of fate can change the path of a life. Sometimes fates are woven together by choices, and sometimes they are woven together by an unseen hand that guides us to where we are meant to be.
While Kamek isn’t always exactly accurate in his predictions, when he does see something clearly he knows it will come to pass. Whether he wants to or not, Daimao’s heir will take his rightful place one day, and when he does it will be with the help of the Koopas.
A girl of the forest clan is born with special features, marking her out as unique even among her own people as a warrior and leader, with her own role to play in Bowser’s ultimate destiny.
The fates of the kingdoms are on the line as the princess of the Arbre wreaks havoc on the lives of two brothers, leading Bowser to look beyond the kingdom he was born to and start to wonder if there was something more for him, something that called him home to a place he had never been.
While destiny weaves their ultimate fates, Bowser heads for the one place he hopes will feel like home after a life of standing apart because of who and what he is.
The Dark Land.
