For the vampire creatures, how about Cassowires? Like the bird species cassowary, that have a record for being dangerous/deadly.
OOHH DUDE THAT WORKS PERFECTLY
Then their monster forms could have even longer anthro sharp talons/clawsss
Ouhhh and the colorful feathers work with the funky blood that drips from em
AND!! the eyes!! Their eyes could change from vaguely off color to full cassowary death stare
Ouh I am having too much fun with this >:}
