Summary
Leonardo was the Leader of the Turtles, the oldest brother and extremely protective of his brothers. He was a focused and extremely skilled ninja. That's what everyone thought Leonardo was, but in reality, he was a Female Turtle forced by Splinter to pass himself off as male. He was forced to pretend to have a deep, masculine voice, which caused great pain in his vocal cords, and he had to endure Splinter's abuse completely alone. Leonardo wanted to be feminine, to be called a girl, not to have to feel a horrible pain in his throat and, above all, not to have the name Leonardo, which every time it was said caused unbearable pain in his soul. And her life changed when she found an injured vampire bat in the sewers and took it to her room. What she didn't imagine was that this was the Heir to the Vampire Throne and that he was more than in love with the beautiful Turtle who saved him.

Summary
After defeating Kavaxas and Savanti Romero (again), the turtles go home and try to go back to a form of “normalcy”. Unfortunately, a shadowy branch of the U.S. government has been investigating New York as the beacon of mutants, time masters, demodragons, and aliens. With the turtles hunted down and placed in a covert max security facility, all “normalcy” is thrown out the window. Now the goal is to escape, and the government isn’t letting them go without a fight. To make things even more complicated, one of the inmates has vengeance on the agenda and if you're not with them, you're against them.
Season 5 seemed to have more filler arcs than actual plot. Retconning the 1987 arcs, the When Worlds Collide arc, the Edo arc, and ignoring the Apocalypse arc, I am introducing a plot arc of real world consequences from the spectacular adventures of the turtles. Alternatively, the reader could see this as a setting that takes place before the aforementioned arcs but after the Demodragon arc. This also touches a bit more on death, and the effects of which on the characters.

Summary
The city quiets, the curtain lifts, and life after the battle begins.
Leonardo has faced enemies, loss, and the weight of leadership—but nothing has tested him quite like peace. With Olivia, he’s learning what it means to choose vulnerability over duty, and to imagine a future that frightens him more than any fight ever could.
He wants to believe he’s enough—for her, for the life they’re building—but some fears run deeper than scars, and love doesn’t always silence them.
The Aria of Us continues the Stages and Shells series—a slow-burn romance about trust, healing, and the quiet courage it takes to believe you deserve happiness.

Summary
Merrill Damian Ramirez is a sixteen-year-old teen who is spending his suspension smoking with his "friend". Nothing too special until a yellow "dog" is being chased by two huge men with tiny dogs on baby hammocks. Instead of minding his business, Merrill decides to intervene and save the creature. What could go wrong?
Shenanigans are part of the adventure, along with a yokai who can teleport, a sassy African American girl, and a group of mutant turtles with frat boy syndrome.
One of those turtles he can't stand! Did I forget to mention, they're soulmates? Le gasp!
Follows the ROTTMNT series with a Lady Ai twist (some episodes makes an appearance, there are some that don't, and there are some arcs I created).
I don't own ROTTMNT.
Act 1: 70 chapters
Act 2: 71 - ?

Summary
“You might as well drop the act. You and I know that I can smell you down here-” fuck, he jerked her thigh ‘til he grazed her core, her legs almost giving up on the spot “-but that’s some good insight you gave me there, sweetheart, I wonder what I could do with this information.”
She wasn’t sure she heard it right, but what she did hear was enough to make her cheeks burn like her skin was the sun itself.“L-Le-Ah!” her voice died down in a moan, he bit her neck, hard. Layla had to fight the urge to let her voice unveil. But his lips didn’t stop there, he trailed her with small bites and kisses until he reached her mouth. His hand, fuck, it covered her neck entirely, his grip on her jaw tight, dictating where she would be looking at.
“If you want this sweetheart, we have to be quiet. Do you think you can do that for me?”

Summary
“You are worth the work it takes to love you.”
Is what Salena was raised to believe. But after her mother mysteriously disappeared and father passed a year later, living with her aunt only provided conditional love (if you could even call it love). Same deal with the only two friends she made at school. Love is strangely hard to find, no matter how easily you give it.
But maybe all she needs is a change of pace? Some new faces, some new friends, some new adventures? Yeah, that'd be pretty nice! A fresh start on this tricky trail of love.
Who knew those new friends would be green, though, am I right?~
Disclaimer: This fic includes themes of violence, abuse, familial neglect, self deprecation, mild sexual harassment and assault, and can overall just get a bit dark sometimes. Each chapter has its own warnings and disclaimers in the beginning Author's Notes that are specific for that chapter. If that ain't your jam, stay safe and scroll past! :3

Summary
When a simple errand for gathering medical supplies goes awry, the four brothers find themselves stumbling upon a deep, dark secret of human experimentation. What should have been an easy undertaking becomes a slightly more complicated rescue mission of a young woman, and things go from bad to worse. Leonardo gets separated from his brothers, Michelangelo strikes a bargain with a sly fox, and Donatello pays the price while Raphael is generally just ticked off by everything. Without their leader they need to figure out where their big brother has been taken to, and thus - in order to find Leonardo - his brothers form an alliance with two women; one an alien tech mechanic the other an actual alien.
A story for those who desire romance, but also crave a little violence,
this is a Mutant Ninja Turtle Horror, Adventure, Romance.
