Mutagen Stories

An unlikely encounter puts the life Sofia Carson had once known upside down. One moment she finds herself sitting in school through boring classes, and the other she is running from Alien Robots, Ninja, and Mutants. Nights that she often spent alone in her room were now filled with adventures on top of the roofs of Manhattan. Every day held something new for her ever since she discovered what her father was working on. Ever since she met 𝘩𝘪𝘮... ｡･:*˚:✧｡ɪɴꜰᴏ｡･:*˚:✧｡ The book could contain some adult topics, but nothing NSFW related, mainly detailed written scenes of battles, blood, mutations, etc. The Cover Art is not mine; a friend of mine drew this for me a while back. Also, English is not my first language, so if there are any grammar mistakes, I deeply apologize. (First published Chapter: 30.04.2025) Last published Chapter: ???)

Cover Art by MariaDeniseBrebros on Deviantart.com A Donatello love story. The other brothers get their share, too ;-) Takes place in New York City about a couple years after the 2014 movie, before the 2016 sequel. The turtles aren't the only vigilantes out there. Another mutant known as the Black Death or the Raven is taking out the Foot, too, so much that the turtles can relax for once. But when the mutants cross paths with this other crime fighter, all of their lives will change forever... *I do not own Teenage Mutant Ninja Turtles or any of its affiliating characters or the artwork/pictures/songs/etc. I own the original characters I created for this story. All media goes to their rightful and respectful owners.*

Under serious editing. I'll update one rewritten chapter at a time, and I hope you enjoy the new version! (Deepest apologies to anyone who read the cringe-worthy old version.)

[This is pretty much an AU pieced together from the various versions of TMNT throughout the years] ----- New York is a big, strange city. In recent years there have reports of mutated humanoid animals, ninja gangs, and missing scientists. There are the "Suit Men" who sometimes get reported, nearly identical sightings of well dressed men speaking strangely... Locals are concerned, but take it in stride. Some even seem to have adapted. Outside the city, the talk is largely dismissed as crazy urban legend. Until the outsiders come in and see it for themselves. Which is just what's about to happen to Aneka Kosmota. Her mother's recent death and her father's new job send them relocating from suburbia to the big city. Everything is strange, even the new, large schools where she meets April O'Neil and Casey Jones. However the path of unusual friends and change that relocating would ultimately send her down was completely unforseen.

Jinny was a normal girl until she saw the turtles and mutagen was spilt on her. Join Jinny on her journey of becoming a teenage mutant ninja turtle.

In the year 20XX, twins Lily and Leo return to a broken down lab where their ancestors once worked, unearthing a new friend, as well as a history that had yet to be told...

I'm still putting the same girls but since I got a new phone and couldn't get Mobizm I have to type it. . . . . . .I wanted to do something different but. . .that obviously didn't last😩

While on a mutagen run, Mikey gets effected by a weird mutagen as it changes his life forever, he gains many new powers and is able to switch between forms, but is it all happy like it seems

{DISCONTINUED} There was a girl who wanted to make a name for herself, one that had entirely been isolated for the beginning of her life. Her family, an odd group, one that will do anything for revenge against the one and only shredder. This girl will help her family with their revenge, anything that it takes. She will make Mother proud, and the rest of her Seishin. A tragic incident brings along a group of mutant turtles, showing her the right way. They open up a new path, they teach her everything she must know, they open her up to new possibilities. Her loyalty is with her clan- she will not allow this group of mutants to stop her. She will use them. But what if she falls in love with one of these mutants? Mutants she swore not to care for, using their connections and strength to get to the man who has abused the only family she has ever known? Now she has grown, now she will understand love, friendship, and the true meaning of revenge. Revenge on the family that abused her- without her knowing her. Revenge on the mutated bones of legendary demons from the land of Japan- spirits that want revenge on the Shredder. Spirits that are in the way of the only happiness she has ever known. Raphael and his family will be there to help her- even if her revenge will slowly kill her. ~~~ "I am the idiot who is caught between the two sides of this battlefield. God help us all." -(Y/n) (L/n

It's that time of year. Camera crews are due to come to the lab for an interview, and the lab staff aren't happy. However, it's even worse than usual as the leader of this camera crew is hilariously obnoxious, and soon the boss has to step in. But even he might have his work cut out for him...

As cliché as it'll sound, Era has known all her life she's not human. At least not completely (well, that's what she's hoping for). And she didn't need anyone to tell her that. Why would she when she has a mouth full of fangs; an ability of flight; and unusual 'appendages' that she has to conceal in backpacks. To know exactly what she is, she returns to New York City, the site of her birth, to find the man who brought her out. Her only clues is a pendant she was given as a baby, along with the name of the mysterious man. However, in spite of being in the city for almost a month she hasn't made the least bit of success in finding him. Luckily, she came upon four mutant turtle brothers who agreed to help her locate the guy. So, not only does she have extra help, she has a new place to chill at. Basically, I'm revising the entire series by adding this original character of mine. However, not all episodes will appear. BUT, before you think this a plagiaristic fanfic version with nothing original or creative, I promise (hopefully) that half of the material you'll read will come from own imagination. So, please, enjoy this fanfic of mine.

TMNTxReader Slow beginning, and I WILL WRITE different endings so all fan girls and boys can be happy with who they end up with. (Y/n) is an intelligent, but awkward biology buff. Your father also works in Biochemistry, allowing you to work with advanced equipment, and advance your studies. One day, you find something very interesting. There is a way to change the DNA of an organism, and still have a living patient. You set out to create the answer, a substance that completely goes through this process, but have little luck. The results are unpredictable. Then, while investigating some leads to this substance, you run across the answer. And they are very attractive.

Kiowa was the child who never knew her parents, never even saw her father's face. All she knows of her mother is a voice, a song. Splinter was told to keep her hidden and safe and that's what he planned to do. But secrets rarely stay hidden...especially for a cat. When you're left alone too long, your mind starts to wonder about things you are told not to think about, you go places you shouldn't go and get involved with the wrong kind of people. Would Kio turn to her amphibian brothers for help? And what would become of the only friend she had? There are things about being an ally to the turtles maybe you don't know about?

I have been getting inspiration for a TMNT boyfriend scenarios so I decided to start one. It will be slightly differ from others. I'll actually have characters or ocs with names and everything decided. I'll possibly find pictures close to what they look like or draw them myself. So the first page with be character info and such, well basic info anyway. But I hope you guys will like it and request some scenarios. Warning that the turtle bros might seem ooc. Possibly. (If you like this please find my 'About Me' book, I have so many fanfictions so I had made it so that I could post Author Notes for all my books incase they all are similar and I don't see a point in writing the same thing in every one. If I have an AN about a book in particular then I would add a small one at the end of a chapter of that book. Thanks guys.)
