#2012 separated au

[renae-the-turtle]

Idea for a tmnt separated au that's - surprisingly - not a rise au. It's a 2012 au

Mikey grows up in dimension X. He's either raised by the utroms and thus has a breathing implement, or he grows up feral and since he was so young, he adapted to be able to breathe the air. Idk what exactly I'd go with but something like that.

Leo is definitely still living on earth with Splinter because his obsession with Space Heroes is adorable and I want him to be able to keep that. Also just. Something something multiversal constant that Leo idolizes/looks up to Splinter in some way in every universe (doesn't apply to all AUs obviously, but it's a very Leo trait, y'know?)

Now I'm not sure if I wanna send any of the turtles to live in space (maybe with Professor Honeycutt or the triceratons or salamandrians) or have one of them live with humans (O'Neil or Jones or a shockingly-not-dead Tang Shen) because there is options, you know? And who knows, maybe Splinter keeps two of the turtles.

If I pick Salamandrians then it'll be Donnie living with them, he'd be best friends with Y'gthba and I guess he'd be in the army too? But as like a tech guy idk. Need some way for him to get off-planet and meet his long-lost brothers, duh.

Or I could have Donnie raised by Professor Honeycutt? Not sure how that would work with the timeline. I'd need to go rewatch the episode where Fugitoid info-dumps his backstory, and depending on the timeline maybe I'd prefer it to have Raph raised by him.

If I decided I wanted a turtle to be raised by Mr O'Neil then I'd probably pick Donnie, neatly erasing the possibility of that awkward crush by having him grow up as April's brother.

If I picked the Jones' then it'd be Raph with them, because Raph & Casey brotp but make them actually brothers haha

If I pick Triceratons.... probably Raph? And then he might get to meet Y'gthba/Mona Lisa early. Or they'd get an enemies-to-lovers arc lol.

On the other hand I could do both Triceratons and Salamandrians, in which Donnie somehow ends up with the Triceratons, is raised by them for a few years, but then gets abandoned on some planet and picked up by Commander Sal.

I could also have Tang Shen survive but without Yoshi or Saki knowing, and without her knowing Yoshi is alive, and she moves to New York and finds one of the turtles and raises him. I'm following a fic in which she raises Miwa and Mikey and I love the idea. (It's called A Mother's Love on ao3 btw) But obviously she'd raise either Raph or Donnie, and Miwa still gets taken by Shredder and raised as Karai. I also don't know if I'd mutate Tang Shen or leave her human.

If I were to pick only one of the above options for Donnie and Raph, and have the other one stay with Leo and Splinter... hmmmm idk who I'd pick actually. It'd be interesting if it were Raph, because of how much Leo and Raph tend to argue, and explore how that dynamic would change with only two of them. Leo and Donnie.... mmm well I asked my sister for a second opinion and she pointed out that those two would likely be too efficient. Not enough drama lol. Leo and Raph would be way more interesting.

Anyway. Gonna think about this more but I like the idea of Mikey growing up in Dimension X and thus being even more of a genius there. Leo still gets raised by Splinter but he's got that Big Brother Sense tm that tells him something is missing and it drives him nuts. Raph and Donnie... it's up in the air (or space) where they're at lol.

Remember this one? 2012 Separated AU where Donnie is raised by Professor Honeycutt.

The fugitioid and his time travel shenanigans knowing the turtles will be the only way he has a chance to make things right. He watches and waits to make sure nothing goes wrong because he needs them all together. So, of course, something goes wrong.

When Splinter is running from some threat he accidentally drops one of the young turtles and they get left behind. The professor tried to return the infant but Splinter, spooked from the previous threat and terrified of losing another child, kept running before Honeycutt could even get close. Curse his metallic body!

In the end, the fugitioid has to stop or risk the others' safety, but what to do with this one? All that matters is they're together in the end right, and he'll come for them when the time comes. So it looks like it's up to him to take care of this one until then.

Luckily Donatello is eager to learn so it's not too hard to find ways to entertain him. However, it is a bit of a problem when he tries to get into things he's not supposed to. Waking up without arms was a terrifying experience for the professor.

Honeycutt told Donatello stories about others like him. That one day during a time of great urgency they will reunite to save their home world. He loves seeing Donatello's eyes light up.

Donatello makes his own armor/suit to look more like a robot like the professor. The helmet also lets Donatello scan and display information in the visor. Let him make him a tech bō with alien tech. Donatello meets his brothers but doesn't remove the armor because he wants them to get to know him and him and not just their lost brother.

[cupcakeslushie]

A while back I saw you mentioned a 2012 sort of separated au and it’s lived rent free in my head since. Do you have anything else you’d mind sharing about it? 🥺

I haven’t expanded on it much. If I do, then I’ll go crazy with it. But Raph and Donnie grow up relying on each other, under the control of the Kraang. They use them to keep the other in line. This makes Raph super protective, while Donnie is always hyper focused on completing any assignments he’s given so Raph isn’t punished.

Raph is allowed to go on missions. Therefore he’s adapted his speech to match humans, but Donnie, connected to the hive mind (he can disconnect if he needs) talks more like the Kraang.

Leo and Mikey are pretty much unchanged, but the two work well together. They run into Raph first, during one of his assignments, and he practically begs them to help him save Donnie. Raph keeps the meeting secret, knowing that Donnie won’t be able to hide anything from the Hive Mind.

I never decided on names for Don and Raph but I’m sure they be something like MT01 and MT02 (for Mutant Turtle).

This absolutely had to be done I’ve been sick with Covid and physically tired but we’re making progress.

Also you can see a bit of Prodigy!Leo’s season 2 design. While I like how he came out I’m not sure about the other Leo’s As this is my very first time drawing them and I did the best I could.

If you’re new to the Mystic Prodigy series have a read

Brother from another ooze AU

2012 AU where Donnie is separated from the others while exploring the sewers as children. He gets caught up in a flood of water that tosses and throws him all through the sewers until he's able to crawl out. Body bloodied and broken he tries looking for home but no matter how much he walks he doesn't recognize where he is. Unable to move anymore he collapses and weakly calls for help.

He's found by Casey and his parents when they hear what they think is a child who fell into the sewers. They're surprised when they find out he's a mutant, but mutant or not he's still an injured child. They take him home, patch him up, and pretty much adopt him. Casey now has a new brother he can rough house with.

Donnie starts feeling a little insecure since he's the only one running around without any clothes. Mr and Mrs Jones buy him large hoodies that can easily fit over his shell. When Casey gets his teeth knocked out playing hockey he refuses to get them fixed because now he looks more like Donnie. (Only better, because his gap is bigger.)

Donnie being the genius with a thirst for knowledge he is, starts reading through all of Casey's textbooks and helping him with his homework. Mr and Mrs Jones start bringing home pieces of broken electronics after stopping him from tearing apart the toaster to find out how it works. Mr Jones jokes about being replaced when Donnie ends up fixing everything around the house.

While Donnie is having the time of his life with his human family his mutant one grieves. All blaming themselves for the loss of their brother. After the accident they all slept in the same room, afraid to let the others leave their sight. Training to be strong enough to never lose anyone again.

When they do leave the sewers and see April and her father in trouble it gives them flashbacks to losing Donnie. They refuse to feel useless and helpless like that again so they try to save them. They take take April on as a sister. Not to replace, but to help fill the empty space.

They do have problems with separation anxiety though so they will follow her around at times. She doesn't know what happened but it must have been awful to make such strong people afraid. So she pretends not to know they're there.

Unfortunately, all the mutant and alien misadventures make it hard to have time to study. So April unfortunately needs a tutor. When she signed up for a tutor she wasn't expecting the likes of Casey Jones. He is apparently one of the top students in the school thanks to his genius brother, DJ, helping him study. They end up going out to a park to study because Casey's brother is a bit anti-social and he doesn't want to stress him out with a stranger in their house.

The turtles follow April, not trusting her out all alone with a stranger. Imagine their surprise when they notice someone already there watching them.

Donnie is trying to get a look at the girl Casey couldn't stop talking about when he got home. He guesses she seems okay but is a big Mama's boy, so no one is prettier than her. Besides, Casey likes her and bros before hoes.

What's that you say? You like love triangles. Well then try my patent pending Brotherly Love Triangle! Casey and the turtles fighting over Donnie's love and attention! While Donnie just wants them all to shut up and leave him alone so he can work in peace.

2012 separated AU

||NO SHIPS||

i haven’t seen a 2012 separated au yet. sooo.. (i bet there is though)

((probably will delete later))

[blackbogmire]

I'm really excited to finally share an ongoing project I've been writing for a couple months now! Good Genes has always been my favorite arc in 2003, and I wanted to find a way to work it into 2012's canon through an AU! It takes place during the arc where Karai is infected with a brain worm, and focuses on the conflicts around Donatello's (failed) attempts at finding a cure.

This fic is basically the 2012 version of "Adventures in Turtle Sitting"
