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.

Summary
“Ah, yes, I’m sure you have many questions for me, including how I know about your fascinating mystic abilities. But your questions are inconsequential, I know all about you and your family. I’m also aware that you turtles are the ones who were responsible for stopping the alien invasion a couple years back, along that giant portal in the sky last year. You and your so called brothers have been quite a matter of interest to me for some time now. It hasn't been easy finding you, but I knew it would only be a matter of time until we did. Of course we had to take precautions regarding your particular abilities. You won't be going anywhere so you might as well get comfortable. Welcome to your new home, turtle."
Leo groaned, ignoring the aches and pains in his muscles as the man turned to go, desperation pushing the words from his sore throat. “Wh… who are you?”
The man paused, glancing at Leo from the corner of his eye, lips pursing in consideration for a moment before he turned to face him again. His smirk returned as he fiddled with the dark glasses on his nose. “I go by many names, but if you must address me, you may call me Bishop.”

Summary
The thing about weird days is that they start out as perfectly normal days.
Casey did what he normally did everyday. He helped his little sister get to school, he helped April get to school, and then he followed his school schedule like he always does. It’s just that patrol didn’t follow their fun-filled itinerary when the Kraang ambushed them.
And, again, it had started out just like any other normal day!
The giant Hershey’s wrapper is telling him it’s so not ending that way.
Or: Casey and April have to deal with being hit by a shrink ray!

Summary
Something is wrong with Donnie.
It starts with a headache. Then the nausea. Then the pain—bone-deep and brutal, twisting him into something unrecognizable. He doesn't know what’s happening. Neither do his brothers.
All they know is that something got into him. Something that should have changed him, but didn’t.
At least… not at first.
Now, the cracks are starting to show.
And Donnie isn’t sure if he can hold himself together. -

Summary
Donatello's favorite color was green when he was younger. He distinctly remembered the reasons why, too. It was the color of his brothers, of plants, and of him! It hadn't been his favorite color for very long, though.
A rebellious adventure into the sewers at the age of 9 ends with him getting lost, and running into a strange mutant woman.
Now his favorite color was purple.
