Summary
Donnie and Leo disappeared without a trace. It was like they just got up and left, leaving their family with more questions than answers. Now as the family desperately searches for the twins, said turtles must find a way to survive and escape. And hopefully before their captor decides that she's finished with them.
***
Or: Hansel and Gretal but let's put Ninja Turtles in it. Donnie really hates that he ever stepped foot in Witch Town.

Summary
There are a lot of dead Krang in the Prison Dimension, it's no wonder there is Empyrean EVERYWHERE. In the water, in the strange plant life - which, okay, Leonardo isn't a very good scientist, but he's pretty sure that there shouldn't be any here - in the damn AIR HE'S BREATHING. Yeah, there's a lot of it. With that, and with the weird time... stuff that's going on, if what Prime told him was true, he shouldn't really be surprised that all of that had... such an effect on his body. Or his Ninpo.
OR
Long-Form fic where Leonardo gets a massive power boost due to his extended stay in the Prison Dimension, gets kicked out of the family due to not being able to fight in a team(also due to the good ol' PD), gets a child, a parent, and an entirely new family, becomes the greatest Battle Nexus Champion in history, experiences the horrors of High School, and so, so much more.

Summary
Leo knows this isn't about him; not anymore. But that doesn't stop the nightmares from haunting him every night, or the fact that he may have to wear a leg brace for a long time. It doesn't stop his shell from hurting, or his breath from catching when the air is too stagnant. Leo knows his brothers are struggling, too. But, in the aftermath of what happened to him - to them - he's having a really hard time getting back to normal.

In other words it's another "the disaster twins end up in the 2012 universe and are menaces to society and their counterparts" but this time they talk about their emotions and all! Also, small disclaimer, all the info I have about the 2012 show is from the wiki and some random memories I have from like, five years ago as well as random clips I see on Tik Tok and Tumblr.

Unless there’s something terribly, terribly wrong with Leo. Bad son, bad brother, useless, worthless.

Summary
Leo had spoken a lot of “last words” in his life -almost always as a joke, but watching as Krang One lumbered towards his slouched form, all grating, metal armor and fury, Leo wished he could have thought of something more meaningful to say as he released his hold of the last Krang and watched the light of the portal close in on itself.
OR:
Leo is recovering from his time in the prison dimension, but the prison dimension was built to keep the Krang confined, nothing else. Even Leo's brief exposure to the prison dimension was enough to make him realize this.Bookmarked by Mistake_Error404
