Paper Mario: Color Splash (Roy G. Biv Version!) by AaronTGP
Fandoms: Paper Mario Series (Video Games), Super Mario & Related Fandoms
28 Apr 2026
Tags
Summary
A rewrite AND canon divergence for Paper Mario: Color Splash that leans into an old fan theory from before Color Splash released: that Roy Koopa was going to be the final boss of the game. In addition to other changes for the fun of it (changed chapter plots, changed jokes, and actual unique characters), the obvious change is having a Roy final battle, with changes to lead up to that climax.
Mario goes on a big adventure alongside his new companion, Huey the Paint Bucket, in the country of Prismia to collect the Paint Stars that Bowser stole and gave to his Koopalings, and rescue Princess Peach, who has her own goal of escaping Bowser herself. Meanwhile, the small but determined Toad got separated from the Princess, and is on his own mission to find Mario.

Look at him, taking care of himself and proving he doesn't need Mario. But somehow, things end up going wrong, and he's got Bowser worrying about him, too??

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
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
On a day most would find impossible, Bowser finally had Peach's hand in marriage. Under the endless starry sky in the Star World Cathedral, King Bowser of the Dark Lands and Princess Peach of the Mushroom Kingdom are to be wed. Suddenly, Mario and Toad burst in, presumably to save the princess.
However, in a shocking twist of fate, it's revealed that the princess was... LUIGI?!
"What grand trickery was this, for the mighty King Koopa to fall victim to almost marrying a faux princess? More importantly, why have his feelings betrayed him as his still-beating heart thumps the same way for the second-place brother?"

Summary
By now, Princess Peach is resigned to her monthly kidnappings. This one's a little earlier than normal, but she expects the usual from Bowser: proposing, wheedling, and finally begging, in that order.
It’s a routine she's pretty fed-up with by now.
Except this time, her first visitor isn’t who she expected.
She's only ever thought of him as another set of hands that orchestrate her frequent abductions. Turns out he's also a snarky bastard who's not overly enthusiastic about his father granting him the supposed honor of being her lifelong slave.
…But he's all she's got in this huge, unfamiliar castle, until Mario comes to rescue her.
And maybe, just maybe, he's a little lonely too, underneath all that sarcasm.

Summary
Luigi stumbled upon a pair of magical earrings that allow him to turn into a woman whenever he puts them on. He's enjoying his time as Lucy when Peach gives him the mission to set up communications with a newly discovered Koopa Island. Only for him to be kidnapped and forced to be their queen.
Bowser has been over Peach for years, but finds himself interested in someone new, Princess Lucy. He was in Sarasaland to discuss peace talks, she was hanging out with her friend Daisy. Who ushered him out far too quickly after introductions. It was for the best though, as Lucy left for her home kingdom, never to return.
That is, until years later, when Bowser reaches out to the Koopa Queen of the Perseann Islands and he realizes it was the princess he met all those years ago. Does she even remember him after all these years? Does it even matter? Bowser has been writing to a new woman for a long time, who he isn't able to see, for reasons she refuses to answer. How will he juggle his love for the woman he writes to and the deep attraction he feels to the new queen?
