Teenage mage ninja turtle.. Wait, what's that! by Glass_Ducks

Summary
Being the youngest was supposed to mean that you wouldn't have to worry about your older siblings. But not in this family! Our resident mutant turtle is brothers with Leonardo, Raphael, Donatello and Michelangelo. Those four are going to get themselves into a lot of trouble and near death experienced, but they always make it though.
There will be suprises, some character get more action than before, the magic of this world will be expanded upon and most importantly familial connections will be the thriving force of this story.
---------------------------------
The story follows my original character from start of the series to its end.The 2003 turtles give me huge big brother vibes, so I gave them a younger brother.
(I will add more tags when we get there)

After being kidnapped by a mysterious organization, the Hamato brothers are separated and experimented on—physically, mentally, and emotionally. Each is told the others are gone.

This is a story of resilience, pain, and the love that holds them together even in the darkest depths.

Summary
When she thought the coast was clear, she quickly crawled out of her hiding spot, her legs stumbling and wobbling as she struggled to pull herself up again. Her stomach felt like it had been twisted inside out, and her limbs had turned to jelly. She clumsily made her way to the still-open portal, which was now slowly closing, and placed a hand against the stone mouth, for support. As she looked down, she saw the swirling energy, lulling her into almost a hypnotic sense of safety, mesmerising her with its whirlwind movement. This was the craziest thing she had ever seen, and yet she couldn’t seem to tear her gaze away from it. The blue hue filled her eyes, a million questions racing through her mind. Where did this portal lead to? Where did the creatures go? Would they ever come back? And most importantly…
Was she insane enough to go check it out for herself?

Summary
AN UPDATED VERSION OF ONE OF MY FANFICS
After a messed-up patrol, leaving Mikey injured because of the three brothers' actions, Splinter punishes them from going to the surface until they can learn to work and adapt with Michelangelo together.
It is then that Donatello created a drug called the BIO (Bionic-Intelligence-Organism) that boosts Mikey's intelligence, his behaviour and his strength.
Hoping that this would lift the punishment, the three brothers went along with the plan and tricked Mikey into eating a pizza with the drug in it, and soon the formula worked
For the time being, the BIO transformed Michelangelo for the better as he is more mature, a lot smarter, stronger and even better at things
But as the drug gets stronger and stays longer in Mikey's system, it begins to turn him into a different person, something cold, something opposite of who Mikey is...Something sinister
Will the family find a way to reverse Mikey back to his natural self or will this dangerous new Mikey be their downfall?

One Last Second Chance by AlleyCatGotYourBack

Summary
The world has ended. The Kraang have decimated the planet, and only a few straggling survivors still cling to life. Among those few are Donatello and Casey Jones. Donatello figures that there's no point in trying to fix what's happened. But maybe he can prevent it from happening all together. So, he does what any normal turtle would do and builds a time machine to take him and Casey back in time and hopefully, from the shadows, they can save their past selves from following the same road to destruction. Maybe then, he can start to be forgiven for not seeing it coming.
He didn't account for how hard it would be to stay away from the version of his family that's still alive and happy.
Casey Jones just wants to protect the only person he still has left and possibly save the world while he's at it. Trying to find a purpose in a world that already has a Casey Jones and trying to find some small bits of a peace in a world on the highway to destruction.Neither one of them are very good at sticking to the plan, however, and soon enough, they'll have to contend with family dynamics, memories, and finding your place in a world with no need for extras.

Donatello Hamato: A Pizza Topped with Soulmarks by CraftyKat147
Fandoms: Rise of the Teenage Mutant Ninja Turtles (Cartoon 2018)
22 Dec 2025
Tags
Summary
Donatello Hamato was among 8 other soulmates. He was statistically lucky enough to have already found 4 of them which left 37.5% undiscovered. Considering the variables it was highly likely that they would find their soulmates sooner rather than later, especially considering the various efforts of his brothers. Until then, Donnie would work figuring out where they came from and how to keep them all alive. Newton knew Leo could only patch them up so many times. ... (Note to self, look into prosthesis and various prosthetics. Ask Leo for help with the squishy bits. *shudders*)
In Which, Donnie unfortunately does not conquer the world, nor acquire Uranium but does manage to find his remaining soulmates, fend off a 'fish'cious fish monster, acquires minions, and fly a spaceship. And maybe just maybe call Leo his twin.

Summary
Leonardo had always been a charmer.
He loved his siblings till the ends of the earth, but he had a mental illness that made everything he touched turn on him.
He had narcissistic personality disorder.
And he loved them! But they didn’t know that and he never made the effort to make them love him. He couldn’t love anyone but himself.
He was unlovable.
They weren’t happy when he went into a coma for almost two years but they weren’t upset either since the hitting, yelling, and pain stopped when he was gone.
If he had died they wouldn’t have been too upset about it.
They must have hated him.They must have despise him.
Since they gave away his mask, his Katanas, his title. To a random human.
So if nobody liked him then why not push his limits? and make their lives a living hell! While also going insane in the process.
Orrr
What if Leonardo went into a comma the day the left the sewer and woke up a year and a half later. And Aprils the leader now!
Most chapters have a song!! :3
