Summary
New York is rebuilt and the Mad Dogs are back to their normal life. A chance encounter with a familiar looking mutant quickly leads them down another path to an earth ending threat, but it isn't their world that needs saving this time.
A story that follows unraveling the mystery of a sister counterpart being displaced from her dimension as the Rise brothers and their family endeavor to lend their aid. In pledging to get her home, they also promise to help solve the crisis her New York is facing, leading to many encounters with both old and new faces. A new set of siblings, a new set of circumstances - one big family coming together to face their greatest threat yet.
Heavily focuses on themes of learning to love oneself, forgiveness, overcoming trauma, and strengthening familial bonds. Features many Rise-ified characters from various iterations, insert artwork for specifc moments (chapters 18, 24, 31, 39, and 50 currently), and is planned for four major arcs. Arc One spans chapters 1-18, Arc Two chapters 19-49, and Arc Three chapters 50-68. Arc Four starts in March 2026.

Summary
Donatello shares a surprising side-effect of their hero status with his brothers, courtesy of fans on the world wide web.
As of the time of this writing, “Mutant Mayhem” relationship tags on AO3 are as follows:
24 Leonardo/Raphael
18 Donatello/Michelangelo
13 OT4
10 for Raphael with either Donatello or Michelangelo
07 for Leonardo with either Donatello or Michelangelo
(Granted, most of these are multidimensional stories and not dedicated MM universe.)Since there are not many MM tcest fics, I wanted to reference some existing stories focused on this iteration for others to enjoy. Of course, each of these will be linked and given credit in the ending notes with the writers notified!

Summary
TMNT: SOM is a passion project of mine, where I will take all 124 episodes of TMNT (2012) and rewrite them to a vision I’ve had for years. This rewrite/au will contain elements and characters from TMNT (2003), ROTTMNT, the Archie comics, and the IDW comics. The goal is to fix the setbacks the original writing posed for the series and help it reach its full potential. This work is also heavily inspired by Avatar: The Last Airbender!
My own original characters will also be included, as villains, heroes, minor, and major cast members. There will be relationships involving my own original characters and canon characters, romantic and platonic.
SOM will include openly queer characters and themes, a racially diverse cast, and an anti-police stance. If any of these bother you, please do not interact with me or my work.

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
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
Hey hello, if you're wondering why I won't do this in tumblr, It's because I'm a fine artist in her 30s trying to make a living, and
There are amazing artist there, sadly cant enjoy Tumblr anymore. Its different now, and you have to be so carefull with everything.just FYI my instagram account and my a03 are separate, so my writing hobby is still personal and fan art is not posted there, yet. But if your curious, just dm me if you want to see more of my art!
Anyway, so I'm super excited about the upcoming comic. However, I am not very happy with some creative choices, and that is the second reason why I write fan fictions, other than the fact i just enjoy writing as a hobby. So, here are my two cents about the upcoming Comic, and Bishop's confusing arc
