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
The last of Casey Jones' family died less than 48 hours ago. Now that the world isn't about to end he may need to start processing that, but that's hard and it's easier to pretend everything is okay. Being the only one to remember the last war to ever happen is totally okay. To be a sixteen-year-old war veteran is totally okay. To be face-to-face with the younger versions of your deceased family and realize as much as you love them you are just the cool guy they just met, is totally okay. Yeah. Yeah. Casey Jones is totally okay.

Summary
The dull lull of a street lamp buzzing overhead distracts Mikey for a while. The soft glow flickers every two minutes, yellowish sparks are spat out from loose wiring as it does. Every time he closes his eyes, he can still see the swirling lights in the darkness of his eyelids. His body aches, but not with the weight of his training. He felt different, different in a way that made his stomach flip, and bile rise to his throat. He inhaled sharply as he sat himself up. His chest ached, lungs widening against his rib cage as he crossed his arms over his chest. His fingers dug into the softness of his arms, pinching him out of his drowsiness.
He remembers dying.
Or,
Mikey accidentally isekais himself into another universe, he does not have a good time.
Or,
Tmnt meets Batman but with a twist or two.... million..

Summary
A 'what if' fic - Mikey somehow convinces Bishop to keep his lightning powers after saving the world from Lord Dregg. And what if his powers affected his mind during his isolation after the Mutagen Incident?
Calypso Mikey is an AU of my own creation, where Mikey keeps his lightning powers! although, due to the fact, it messes with his mental and physical state after the Mutagen Incident. a world where only two humans exist in the entire wasteland that was once a beautiful planet full of life. a universe where Mikey (still) found the Oasis but made it into his own home... a kingdom for many mutants that wish for a home, family and peace. but due to only having his dear Ice Cream Kitty and his brother's pet, Chompy, his powers mess with mind, making him loose many of his memories of himself and the people he once knew.
[this au is an inspired by EPIC the Musical!! TYSM MR. JALAPEÑO!!! and dw, Mikey doesn't SA Casey, bro just gets clingy with him and tries to manipulate him to stay with him so he won't be alone again.]
Edit: screw it, i post new chapters whenever- i can't follow my schedule.
