DISASTER HUSBANDS AU FULL LORE
I realized that ive posted basically nothing for this au except for art, so here we go! ill use this post as the main hub for all the lore. I’ll probably be making changes to it while it grows so keep an eye out!
Warning: Everything published before this post is now non-canon simply because I’ve lost track of everything I’ve posted about it
Basically, it started with an incident in Donnie’s lab, he was messing with Kraang portal tech to see if he could give it a new purpose, but it went wrong and started malfuntioning, letting off a giant pink blast in the lab. Casey was standing too close and Leo jumped forward to grab him, but by the time the flash of light stopped, both Casey and Leo had disappeared from the lab.
Here’s a goofy version of that story (this is technically non-canon but you get the gist):
This blast (which Donnie originally thought had disintegrated them,) actually just sent them to another dimension to an alien world. Unfortunately for all of them, time moves MUCH faster in this world than it does in the og universe (For simplicity i’ll call the tmnt universe Earth and this new one Sinmar (these are the names of the planets but THEY ARE IN DIFFERENT UNIVERSES.) What was 3 months on Earth, was 30 years on Sinmar.
Leo and Casey fell from the sky on a new planet called Sinmar and immeadeatly found themselves on the receiving end of an EXTREMELY hostile world. The landed in the middle of a jungle with no people in it for the pure reason that its basically unlivable. Sinmar lives in a post-apocalypse, formerly having been a greatly advanced planet with multiple sapient species, became a wasteland with a dwindling population after The Reset (as its called on Sinmar.) This event caused the rapid mutation of the flora and fauna and massive changes to environment, with the mutations creating massive fields of invasive flora that choked out and killed ecosystems and fauna that became hyper-predatory monsters that roamed the planet and are drawn to populated areas, and the changes to the environment creating massive dry or frozen wastelands; most large bodies of water have almost completely disappeared.) This planet that had very little ocean even when it was healthy, so when it dried out even more it turned the planet into a massive desert.
There are few locations that can sustain humanoid life, and the few that do exist were quickly overpopulated with massive cities, all protected by some form of massive wall, natural formation, or if theyre lucky a force field. All these cities exist in their own little bubbles, isolated from the wastelands.
In their 30 years on Sinmar, Casey and Leo quickly became outlaws, finding the cities to be dystopian and impossible to live in due to the overpopulation and disease, they began selling things they hunt and find in the wasteland in black markets. After becoming notorious for escaping high security prisons a ridiculous amount of times, they started almost constantly staying on the move as to not be hunted down. They are basically being constantly pursued by a slightly insane detective obsessed with catching them, his name is Dean. Dean is a pathetic man failure and i love him. Dean has been chasing them for so long Casey mockingly calls him their third (yes there is constant homoerotic flirting between them i cant leave you guys hanging (cough cough “Chel is off limits” scene from Road to El Dorado.)) Every time they get away from Dean’s grasp they leave a taunting note, signed wanted posters, or even flowers and candy to which Dean promptly flips his desk (he does that a lot (he’s racist against furniture))
5 years into their time on Sinmar they started dating, and 10 years after landing in that jungle in Sinmar, they were married in the middle of a fight (Pirates of the Caribbean style.)
They had been dating for a few months when leo lost his leg after he was trapped under a rock slide. He was badly injured, they were in a desert with barely any water, he was slowly bleeding out and becoming less and less responsive, so Casey did what he felt he needed to and sawed off Leo’s leg (while he was conscious.) Casey feared he wouldn’t survive and Leo’s leg got infected multiple times, so out of desperation he went into a city to try to get him to a hospital, but Casey accidentally let it slip that he was the one to cut off Leo’s leg and he was quickly arrested. In addition, the city basically took custody of Leo (they had a very unethical eugenics study program, and having never seen anyone of Leo’s “Race” before, they wanted to experiment on him,) Casey was not allowed to see him because they weren’t married or related and just like that he lost Leo to the system. Casey, fearing that Leo would die alone in some lab, broke out of prison and basically kidnapped Leo and fled to the wasteland with him. Leo barely survived and Casey eventually made him a prosthetic leg so he could walk again.
Over the years they were there, Casey figured out how to work the Old Tech of Sinmar (the planet is littered with old non-functional technology from before the reset) and used his craftiness to make gear and to try to find a way home.
About 15 years after landing in Sinmar, they stumbled across a little crab creature called a Grabcrab, which they basically adopted and Casey named Ricky. Grabcrabs are technically sapient but dont speak and are more driven by emotion than thought and less capable of advanced thought than humans. And 19 years after landing, they found a giant dog that Casey refused to leave behind and they named Brutus, Casey BEGGED to keep Brutus and Leo kept saying no, but as they walked for miles with Casey still begging to keep the dog, Brutus just followed them home, he had a giant dog bed and bowl in their base and Leo and Casey were still arguing about keeping him. Much to Casey’s dismay, both Brutus and Ricky prefer Leo over Casey, he calls them all traitors. Brutus is a dog the size of a horse who thinks he’s a lapdog.
They did have a period of time where they split up and had some bitterness towards each other, mainly from having been struggling together for so long and just boiling over one day, i call it the Divorce Era and they were split up for a couple months around year 24 after landing in Sinmar. When Casey came back debating on whether to try to make up, he found their base on fire with Leo trapped inside.
They both have a lot of near-death experiences and can never split up bc theyre bonded through shared trauma ngl. They are nonstop banter and arguing like an old married couple, and they both lost some marbles over the years, just a tiny bit (youd have some screws loose too if you were stuck with Casey Jones for 30 years.) They rubbed off on each other, with Casey becoming wiser and more responsible and Leo getting looser and wilder at times. Casey has called Leo by several thousand pet names over the 25 years they were together and Leo has called him by the ever-affectionate name: Jones.
-They constantly argue over who took who’s last name (there’s no legal system of marriage in the wasteland so they just make it up as they go.) Casey calls Leo Mrs Jones just to annoy him.
-They call Ricky their firstborn son (they dont talk about how Leo suggested eating him when they first found him)
-There’s an AU of this AU (im considering making it canon) where Dean joins them and actually becomes their third
-Casey has unnecessarily risked his life many times to get parts for Leo’s leg
-Leo basically only calls Casey by his last name, and if he calls him by his first name someone is either actively dying or the dog sat on Leo again
-Dean is a total diva that does NOT belong in the wasteland but he goes anyways bc he’s insane
-Casey and Leo have saved Dean’s life multiple times and he HATES them for it
-Ricky hides in Casey’s shirt when he’s scared
-Casey hates all his wanted posters (Flynn Ryder style)
-They both drink and smoke a LOT
-Leo is serious and grumpy 90% of the time but when he’s not you’d be certain he’s lost his mind
-They eventually make a small base surrounded by massive Jurassic Park style electric fences
-The cities basically have a monopoly on most types of medicine and other necessities, so the guys make money by smuggling contraband into cities and selling it
-Leo once slaughtered an entire group of wasteland scavengers because they kidnapped Casey
That’s all for now, I’ll be periodically updating this post, the most recent updates will be In purple
