This is Saturn's Crobat (Reverie/Suisui PGAU version), fooling around with a human appearance. YES she is a Pokémon YES she is a vampire any further questions? (plenty)
A pale young human(ish) woman in her early 20s, with bright gold eyes, long purple hair, and a slightly underfed figure. She is a very stereotypical vampire, with pointy fangs and a goth fashion sense. Around 5' even (152 cm).
Your tropey haughty vampire girl, bold, stubborn, somewhat naïve and foolish, easily flustered despite herself. She thinks she is much smarter than she is and is overly proud of anything she sees as a virtue or accomplishment, always wanting praise. Has something of an obsession with her Master.
She is definitely down to clown, let's just get that out of the way now. She is pan and more than happy to experience the ~world of humans~ (in bed). Note that she is 1. a vampire and will definitely be hoping to feed on anyone she's with, and 2. a Pokémon, and like, if you're not into that, respect. You're valid. Things do not have to go there!
No, and please don't tell him, solely because of rule of funny. It's SO much more hilarious if he never finds out. Crobat will also be pretty pissed if you spill the beans. He knows this woman exists, but not who she is.
