Summary
Anton Zeck has never really had a friend he can trust.
He's not a fan of the Hamato brood, Coward Jones, or Nosey O'Neil. He's been shunned for something he can't control and most days he is filled with resentment of his little sister, Angel.
And just when he thinks he's finally free from dealing with the Purple Dragons, they rear their ugly heads again. The most he has is Karai, who he prays never opens her mouth about their initial meeting.
But when Owen Rocksteed, the younger cousin of April O'Neil comes to the city, he finds his spark had never left; it only lay dormant. Owen is the exact person to help him find it again.
Underneath it all, the strings of fate and family bring them all together. Being separated was never an option; for any of them.
(If you want all the tags, look at the OG pandemonium. The only difference is NO SMUT. They kiss and such but not actual smut>)

Summary
¿Qué hiciste roja? _ dijo Casey mientras sus lágrimas caían al piso.
No lo sé, lo juro no fue mi intención _ dijo mientras abrazaba la venda de color morada en el piso llorando por querer volver a ver a su amigo Donatello.
Lentamente un chico de 15 años abría los ojos aturdidos por su sueño pues solo escuchaba su nombre mientras este miraba a la chica de rojo antes de desaparecer mirando hacia un lado mientras observaba el sol llegar a su ventana con calma.
Buenos días _ dijo para sí mismo mientras sonreía antes de levantarse para ponerse la ropa del día, después de arreglarse mientras bajaba hacia la planta del comedor donde estaban todos los soldados comentó posiblemente su segundo plato del día.
Joven Toshitsugu, hoy durmió más de lo habitual _ dijo uno de los reclusos mientras miraba como el reloj marcaba las 12 del día mientras el chico sonreía acercándose.
Volví a soñar con aquella mujer, no sé quién era, pero sé que era especial _ dijo sonriendo mientras le servían algo de comer antes de tallar sus ojos.
Bueno lo que sé es que te espera un regaño por desvelarte y faltar a el entrenamiento de la mañana _ dijo mientras miraba al joven comer en silencio mientras sentía un poco. -

Summary
Pretty much just what the title says. Mainly 2012 turtles, but I’ve got some 2018/2003 in the works. Maybe even Mutant Mayhem one day!
It's a series of OneShots/Drabbles that may be focused more around Donatello than other ninja turtles because I find a mini Dee absolutely adorable!
Feel free to drop requests for him or other turtles as tiny tots and I’ll see what I can do!

Summary
His attention was shifted to his big sister, who, instead of working her way up to her feet, stood on all four legs with such ease, like she’d been quadrupedal for her entire life. Now that she was up Mondo could see how different she looked—spikes infected her back and tail; thicker, shorter limbs; and elongated claws that ripped straight through the rubber of her boots. Her goggled eyes were locked on Mondo and something steadily dripped down her chin.
Drool.
Mondo didn’t know how this day could get any worse.

Summary
Oroku Kazuo loves his brother... perhaps a little too much.
A tragic accident resulting in death (temporarily) stirs up feelings in the Oroku brothers that were thought long gone.
***
"Well?" Krang asks, his voice brimming with anticipation after two whole minutes have passed without Kazuo giving any sign of himself. "What do you say? Would you like to work for me?"
Kazuo looks directly into Krang's crimson eyes, blinks once, and strokes his hair thoughtfully.
"I don't know," he admits, his voice alive with possibility. "I know one thing for sure: Saki is MINE. I'll never give him up again. Wherever he goes, whatever he does, I will stay by his side. That's what I want." He pauses for a moment, and then his lips twist into a smile that is both terrifying and cruel. "And mercy on whoever tries to stop me." -
