Chapter Text
Okay this is a bit embarrassing to put up |D but okay. Saw some modern KH AU ideas floating around, and my brain went ahead and daydreamed about my own version enough that I drew pictures |D Sticking things into loose modern fantasy settings is a good exercise. But I give you … ehhhh Heart Transplant AU I guess |DD
Basic ideas:
1 Sora was born with an abnormally large heart, Roxas and Ven ended up being born with some sort of heart defects/problems that they ended up using pieces of Sora’s heart to fix.
2. Xion is an old friend of Roxas’ that ended up having heart trouble as well, and was a perfect match with Sora too, so they did the same with her, but at a later date. (so Sora has had open heart surgery twice, and the other three only once )
3. Sora makes cheesey comments of “Their a part of my heart just like I’ve become a part of theirs” and it makes them laugh, cringe and roll their eyes
4. Sora, Ven, Roxas, and Vanitas are two sets of identical twin, fraternal quadruplets. Ven and Roxas are identical, Sora and Vanitas are identical twins, but all four of them were born from the same mom at the same time
----------------
More detailed synopsis:
First all the quad’s parents are both dead, and are just nameless faceless NPCs because I couldn’t think of anyone that I wanted to torture with having quads XDDD The dad died of cancer when the quads were 5, and then their mom got killed via snapped neck from whiplash in a car accident when Roxas was in the hospital. |D Because I didn’t want to deal with putting the parents in there and needed Ven to be adopted by Eraqus.
For Ven and Van, yeah, they were kidnapped as newborns by Xehanort. There’s this made up heart condition that I’m deliberately being super vague about because I’m not a medical expert and don’t wanna be called out XDDD But Xehanort is obsessed with figuring out a way to prevent it. It’s genetic though, and he found out that the quad’s parents had markers for it, so he nabbed the two to watch grow and do experiments on to try and figure out what exactly causes the disease and how to fix it. Good intentions, bad actions. |D
They were eventually rescued when they were 11 yo though. Roxas and Ven both ended up with that heart problem, and when Roxas’ issue started manifesting in crappy symptoms that left his really sick his mom took him to the hospital that Eraqus works at because Eraqus is famous for working with heart troubles. At the same time Terra is in the police work, and found the missing child reports a few years ago for Ven and Van, and is kinda obsessed with them. Eraqus stays out of the police work because he doesn’t really like it, but after working with Roxas, and talking with his mom and finding out Roxas and Sora have twin brothers that were kidnapped from the hospital when they were born, and some passing conversations he had with his buddy Xehanort, Erqaus figured out Xehanort had the boys. So Eraqus agreed to set up Xehanort to arrest him and figure out where he was hiding the boys. He feels somewhat responsible for the boys’ fate because of being friends with Xehanort and not seeing his actions sooner.
Vanitas is kinda crazy because Xehanort tended to talk to him like he only existed to be there to fix Ven, and then also tried some DNA splicing on Vanitas to see if he could erase the heart issue genetics that way, and that’s why Vanitas has black hair and yellow eyes. He also has an unhealthy obsession with Ven becaaaause that’s how he is in the game |D A lot of this stuff is just me giving my brain an exercise of taking what happened in the games and porting it over to a modern setting |D
Okay, and then for Xion 8′D In order to have her adopted by Axel, and keep her backstory of being a science experiment I had to give her crappy parents. |D So I just kinda grabbed Braig since he’s pretty much Xehanort’s right hand man in a way. But pretty much Braig has that heart disease marker, and Xehanort was like “hey, go make a kid with this lady that also has the marker so I can study them”, and Braig was like alright fine whatever =A= and tadaaa, Xion was born. Because she couldn’t come from a replica |D But Braig is a dick, and super neglectful of her because what does he care, she’s just there for Xehanort to study. But Axel finds out about it and took Braig to court to try and get custody of Xion away from him to get her away from that life. Axel and Xion had no idea about Braig’s involvement with Xehanort until Aqua presented Xehanort’s notes on it to the judge.
