Summary
“Hmm.” His Master mused. “Now that it’s woken up, it won’t be able to return into its cryogenic chamber. It’s useless to me in that weakened state. I suppose I will have to make a new one.” He stated. “Specimen, dispose of it.”
He visibly twitched. His heart started pounding in his ears. The shouts from the others faded from his mind as all he could hear now was ringing. The small one’s head tilted up, her big eyes staring right into his own.
He had to move. He had to obey. But he-
“Specimen.” His Master said.
And suddenly the noises were back. Too loud. He forced a step towards her. Then another. His body was stiff, his fist closed so tight his knuckles were turning white.
He kneeled in front of her. Her head moved to watch him. He placed his hands around her shoulders. He was shaking. Why was he shaking? This was just a mission. Why couldn’t he do this?
He pressed her shoulder harder, squeezing her lungs together. She was so small. So very small.
“Don’t ya fucking dare, ya monster!” The red one yelled.
She yelped.

Bishop figured that creating mutant turtles was his best bet at defeating mutant turtles. It didn't go quite as expected. For anyone.

Inesperadamente, cuando descubren la creación de un nuevo mutágeno llamado NEO-M7, los chicos creen haber encontrado una oportunidad para salvar a su padre.

Sorprendidos por encontrar a otro mutante, Leonardo toma la decisión de ponerla bajo su protección en un intento por descubrir y detener los nuevos planes de Destructor y salvar a su padre. Y nada tiene que ver que Morgan posea los ojos más azules y hermosos que Leonardo ha visto en su vida.

They need a little brother by Glass_Ducks

Summary
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 though what would happen if they had a younger brother.
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.
(I will add more tags when we get there and probably change the title, since it is kind of misleading in some degree)

Summary
Because Mikey’s not paying attention to what’s in front of them, Leo sees it first through the thinning fog. He thinks it’s a tree trunk at a glance, tall and slender and curving oddly where it rises above the others. Then it moves, bending as if in a wind, and by the time it twists around to face the car, Leo realizes it’s not a tree at all.
“What,” he says, feeling entirely too small in the open-top Jeep.
Mikey, who went through a dinosaur phase that lasted the entirety of his pre-teen years, points at it and declares, “Sauropod!”
“Animatronic,” Leo says, “right?”
“Right,” Mikey parrots automatically. Then, more slowly, “I mean, it has to be. Right?”
“Right,” Leo agrees, but his heart isn’t in it.
The first Jeep has slowed to an abrupt stop, and theirs slows to a stop behind it. The dinosaur trumpets at them, like the elephants at Mikey’s zoo, and half a dozen other slender necks rise out of the mist at the call to peer in their direction.

Because he only wants to return to his legacy back in Costa Rica, but it seems he has a duty to carry out first before he can go anywhere, whether he wants to or not.

Two Princes by ShinyMechAngel

Summary
After listening to the song "Two Princes" by Spin Doctors, my brain went "what if Disaster Twins?"
As much as I tried to keep this on the more innocent end of the T-rated spectrum, Leonardo refused to not go all overconfident playboy. I think he might have been trying to act so off-putting there was no way Donnie wouldn't look better by comparison? He was trying to help, he swears.
But also, when is he ever going to turn down the opportunity to annoy his brother?or: The Disaster Twins are interested in the same woman. Donnie is significantly more interested, so Leo opts to wingman in a very questionable way.
