I had a fever dream about this so uhh congrats I'm yapping about it now
What if Jason gets turned into a vampire (this is going off the not actually burns in the sun just nocturnal vibes) like he leaves for a walk after an argument with Bruce though he saw someone in a back alley and Wham wakes up in the hospital. His teeth hurt like shit, his heads fuzzy, and everything is wayyyy tooo loud, on one side Bruce is sobbing into his hands that he's a terrible father while Alfred tries to comfort him, and on his other one Dick is nervously texting the teen titans. He sits up and asks dick,
Dick: Oh, hi buddy didn't realize you were awake
Jason: Dick what happened
Jason: sigh... Can I at least have a mirror
Dick: it depends on its silver content?
Jason: ... ... Are you making a joke about medieval vampire superstitions...
Wait.... There's bandages on my neck...
Feels his teeth- fuuuuuuuck
Long story short they get sent home with a huge thing of coconut water and a pamphlet.
Good news: drinking blood isn't necessary, the whole dying in sunlight thing is a myth, and hey cool powers
Bad news: your everything gunna hurt for the next month and you're going to need to relearn how to speak as your teeth grow,
Honestly not much changes other than Bruce having another child who climbs his fucking walls and awkward questions.
Jason starts bringing a thing of coconut water with him every where imagine getting in fight with this small child and you get a cut and he just going ah fuck and start chugging a thing of coconut water and your just standing there cuz wtf
His powers, can see in the dark, really good healing(not like instant but in a can live through shit people usually can't way), very good hearing, can turn into a bat (he now says that if Bruce dies he must become the next batman for this exact reason)
He lives the joker incident and the next time he sees Joker after healing/being grounded, Joker immediately is like HOW ARE YOU ALIVE I FUCKING BLEW YOU UP WTF and all he says is idk and kicks him in the groin
He eventually reworks the robin costume to have slightly more classic vampire vibes and every time someone asks him about the costume change he goes huh? What costume change and grins widely
Eventually he notices Tim stalking them and flies right behind him and asks whats he doing, Tim almost falls off the building, they soon become best friends and Bruce basically has another gremlin child to deal with
I like this a lot. I hope Jason also turns into a bat.
