Somewhat related to your bat yearning, I would love to see more vampire hypno art! There's such a wonderful kind of danger to them, and the physical vulnerability that comes with offering up your neck to them is just too enticing. I love situations where the victim/subject abandons fear and rationality, and is entranced into willingly giving themselves over to the pred.
Incubi are a close second, and with both of these creatures they come with the added benefit of having lovely wings that be used to artistically frame the composition, or block the world away from the subject so their attention is focused on the hypnotist, and them alone...

Giving into the temptations of evil beings is a big recurring theme in my kinks lmao
