Author's Note: Reverse!Turtles is a TMNT AU devised by mellowmonsters on Tumblr. If I could link you to the Masterpost I would, but if you just search it up on Google you're sure to come across it. I do not own Reverse!Turtles! I'm simply a big fan. Shoutout to the true owner! Basically, in this alternate universe, the personalities of all the characters are reversed. Leonardo snapped under the pressure of leadership, so now he has brain damage and an insatiable desire to be led; Michelangelo is a bloodthirsty animal who kills whomever he wants; Donatello is an apathetic sociopath with a taste for experimenting on live subjects; Raphael is a crybaby and a pushover, utterly traumatized by what his brothers have become. Splinter is a neglectful father who doesn't care what his sons do beyond training.

In this AU, the birth order is the same, but Donnie and Mikey are the dominant brothers (or alpha males) while Leo and Raph are the meek ones.

This story is rated M for language, violence, smut… uh, basically literally everything that could be considered mature content. You have been warned!

If you like what you see, please let me know in the reviews! I think I'll only continue this story if people show an interest, so I'll think of this as a little test run to see if readers buy what I'm selling.

Note that this next bit is not Chapter One but merely a prologue/teaser, a little snippet snatched from the middle of the story. Enjoy!


Prologue

"Aww, c'mon, brah." Mikey tilted his head, speaking in a sing-song voice. "I was just having a little fun."

Donnie didn't look up as he flicked the needle in his hand.

"And besides, it doesn't even have to be me," the orange-masked ninja went on, craning his neck so that he could better view his brother. It wasn't exactly easy to see when the youngest turtle was strapped down to a metal table, but he made do with what he had. "You could just use Raph. That big baby won't even put up a fight."

Don pressed on the syringe until a few droplets squirted out the top, and his mouth curved up in a smirk. His stained lab coat swayed as he turned and looked down on his baby brother. "True enough." He took several paces forward until he was practically standing directly above his soon-to-be-victim. "But I want it to be you, Mikey." The smirk widened into a grin. "Why, you're my favorite."

"Awwwwwww," Mikey crooned, batting his baby blue eyes. "I love you, too." He flinched ever so slightly as the needle slid into his skin and injected whatever hellish poison Donatello had fancied that fine evening. Up until that moment, Michelangelo had been trying not to let Donnie get to him, but it wasn't long before he broke into a bout of demented laughter.

"I'm going to fuck you up so bad when I get out of here!"

"Mhm."

"You fucking cunt." He jerked against his restraints. "Take a bath!"

Donnie snorted. "Do you even know what a bath is, you neanderthal?" Donnie never bothered with personal hygiene, but Mikey was so animalistic that it wasn't uncommon for both of them to reek of dried blood by the end of the day.

Mikey offered no response but merely descended into twisted laughter again while Don readied his scalpel.

It was true that he could have experimented on anyone; Leo and Raph would have made much tamer victims. But he didn't want tame. He wanted to subject wild, insane Mikey to his will. He needed to remind his younger brother of where he stood in the food chain.

In a word, he needed to be the alpha male.
