Summary
You disguise yourself as Princess Peach to help Mario and Luigi rescue the real Peach. The only issue is that it'd be a few days for them to return, so you try and make the most of it in disguise. But Bowser has grown to like you! However, you see more of the koopa than led on, and how much of his more true personality he had been hiding... And maybe, something a little more than that.

Summary
Bowser was sitting on his throne and thought really hard. And how was he thinking he was only getting angrier and small puffs of smoke kept flowing from his nostrils. He heavily sighed and leaned back on his throne. He wiped his eyes. It was really visible that he was confused and he didn't know what to do. He clenched his fists and slammed the handle on his throne with his right hand. A small Koopa next to him got startled by the sudden movement. He quickly repositioned his thick old glasses and took a step back. He watched Bowser with a corner of his eye. Bowser didn't know what to do. He thought that today he would talk to Peach, maybe propose to her (again) and if needed he would kidnap her! He didn't expect that he would meet another princess that's Peach's younger sister! Bowser sighed again and turned to the small Koopa on his left...

Summary
You are a gray toad, a toad in the Mushroom Kingdom where the vibrant colors of your kin are the norm. Most toads are brimming with energy and chatter, but not you. You've always been more introverted, often wandering inside the kingdom in solitude, content in your quiet life.
On a fateful day, Bowser kidnaps you in your sleep. But as he leaves you for a bit, you were dragged through a mysterious pipe that leads you to different dimensions within the Mushroom Kingdom.
Each world you find yourself in is a warped, nightmarish reflection of uncanny versions of your friends. These alternate realities are not as you know them; they're broken, twisted, and haunted by their own despair.
As you navigate these strange and unsettling dimensions, it becomes your mission to bring some semblance of warmth and hope back to these fractured versions of your friends.
Your journey is one of healing, showing them kindness, love, and perhaps even redemption. You hoped you can restore them to happiness and bring them home to your dimension
(Gender Neutral Gray Toad Reader)
(Based on Creepypasta's and Mario Madness V2 Mod)

Summary
Thick sheets rustled as you climbed into bed next to Bowser, wrapping your arms around his torso. Scars littered his body, most too recent for your taste. The takeover had been violent; toads were still scrubbing blood from the streets and burying bodies. Bowser still flinched when you touched him, and you could see him looking at something you couldn't see. Princess Peach's death was still weighing heavily on him.

Summary
“Are you outside? You're supposed to be resting!” Rain hit your skin as you stepped outside and a red-orange glow emanated from the forest. A wet branch smacked your face as you followed the light. The trees only got denser as mud squelched beneath your boots. “Bowser!”
Sharp black crystals poked at your legs, the mud slowly becoming grittier until solidifying into rock. The trees gave way to a clearing, where you found what looked like an incredibly large version of Bowser lying in…something. “Uh, Bowser?”

Summary
An empty bed woke you for the third time that week; it was getting increasingly common for you to wake up in the middle of the night to a missing fiancé. And it was only getting worse the closer your wedding got. Finally you slipped out of bed, wandering around the castle until you heard voices coming from Boo’s study.
“Bowser?” You called as you pushed the door open, “…and Boo? What’s going on?”

Summary
“I know you didn’t kill him.” Suddenly your voice was stern, almost harsh. “I know who it was.”
“No, Y/N, you don’t,” Bowser growled.
“Yes, Bowser, I do.” This time your voice was harsh as you bared your teeth at him, “And if you don’t tell them, I will.”
“No!” He grabbed you, pinning you to the floor. “You can’t know that!”
“I was there.” You bit his wrist, the iron taste of blood filling your mouth. “I was always there, you fool.”
