They are not human. [Cryptid! Bat Boys AU. Remake because the original one got removed. All characters are 18+]

Having lived in Gathom your whole life you've gotten used to the odd things that often happened in the city however you never expected to be this.

Bruce Wayne is a Vampire.

Grayson is a harpy/bird creature.

Jason Todd is an undead creature.

Tim Drake is a lovecraftian Eldritch creature.

Damian is a Demon-like creature born from a vampire (Bruce) and human (Talia).

I wanted to add Cassandra Cain to the personality but I couldn't think of a cryptid for her to be so please leave suggestions in the comments for what I can do with her.

Update: I have added Cassandra and I have made her an automation/mechanical doll who was cursed to have consciousness like a human as suggested by commenter @NakiB.

A different commenter, @Dagger_Blade suggested to make her a shadow cryptid which I also really like the idea of and I might make an alternate version with that instead but there's no guarantee.
