Will they survive intact and get together again? or will they stay separated like lost puzzles "TURTLES! STAY DETERMINED...." (image not mine, belongs to Glozy Blazey)

The apologies. I believed. They were truthful. But the memories of my past. The words. I am Mikey. The fun loving turtle. That is a memory. My brothers are worried. I am too. But it's up to them to save me. Before it's too late. Picture source: https://zelgadis55.deviantart.com/art/And-One-to-Grow-On-ch-20-564598488

So you already know what this is about based on the title... Enjoy! 😊

You're regular teenage girl who's starting her first year in high school by moving to New York city, home of the Teenage Mutant Ninja Turtles, with your big brother or sister. you were supposed to have a regular high school life but it ended up being something different.......

[THIS FIC HAS BEEN DISCONTINUED] Four infant freshwater turtles in the wilderness are accidentally mutated by a strange ooze. Being given wings of raptors (predatory birds), they learn the ways of surviving and getting along as a family with the help of Hamato Yoshi (Splinter), the one who found them and adopted them as his own children. This is a TMNT 2k12 AU

No, it wasn't Leonardo this time; it was Michelangelo. The young innocent turtle was taken by the Shredder and was beaten and bruised. The three older brothers had found him lying in a cell barley breathing. They had taken him back to lair so Donatello could try to heal him-he patched up his cuts but the youngest turtles eyes had refused to open. - (Re-uploaded)

Mikey couldn't take it anymore. When everything got to much for him he sometimes started hiding in a mask of happiness to keep being like he always was. It's no wonder his brothers didn't notice a thing. Lately he's been putting up his mask more and more. But now... He can't take it off anymore. He's become a fake, a liar, an empty version of who he used to be while the his real self is locked inside. How will Mikey take back control? How will he stop hiding in his mask? And what was he gonna do now that every body else starts to notice somethings off? And what was that voice in his mind? I DO NOT OWN TEENAGE MUTANT NINJA TURTLES

It's been a few days now since the gang left Xaava-Dal and the Aeons. They had found and lost the first piece of the black-hole generator and are now hatching a plan to retrieve it from the Triceraton flagship.

This is just an idea I had when I first saw the episode title back before it came out. This is my first fanfiction and I know everyone says this but please don't judge too harshly XD There will probably be a few mistakes as I go along but I hope you guys enjoy anyway :) Thanks!
