Yes... I did make a bat form to my last Vampire Johnny fanart...
This is what I figured he'd look like.
No, I don't think he'd get blue eyes or anything if he became a vampire.
I just kept his original colour scheme. At least make him stand out from Dracula and Mavis' bat forms.
So I gave him brown fur with a light red tint, and I kept his brown eyes too. Though they look more red 'cause it's blending with the other colours.
