i don’t want to spoil but i guess i have too
the vampires turn into free soul vampires which are vampires that still keep there powers but are now immune to things that usually cause vampires to weaken basically hey are normal bat ponies but with vampire powers that can now work in the sun
they eat all kinds of foods including meat sine they have sharp teeth now and it just becomes apart of them
there wing colors are brown and their eyes are normal unless they get angry or try to scare an intruder
they can reproduce but only with the help of a spell
despite being undead they can digest food, absorb nutrients and well…you know go to the restroom
they can turn into bats
you might not even call them vampires but just bat shape sifters but the term vampire is just use for simplicity reasons
vampires are still immortal as long as they get proper nutrients if an old vampire beaks a tooth they might still get nutrients is with soft food that are not enough until they just pass away due to age but Dracula is currently the only one who is immune to this because of a spell because the vampires NEED their leader
if a vampire like this gets really angry for an extended period of time they might get symptoms of the old vampire which the main one is increase blood thrust but they can revert back when they relaxed or have help
