Wow, this one actually gets a full redesign! This is Vespera, a werebat who I made in 2017. Check out her evolution here: (link)

Her colour scheme, body type, and uh... cup size have changed around a fair bit. The early versions were supposed to be chubby, but I wasn't good enough at anatomy for it to come across. For her latest version, I'd known for a while that I wanted to make her bulkier and hairier, with a flatter chest - and with a colour scheme that wasn't too garish for her backstory. Speaking of:

In 1955, a young woman worked as a lab assistant. An animal lover, she loathed to see innocent critters like bats being used for strange genetic experiments, so she sneaked in at night to release them. But with all those wings flapping around, she pressed something she shouldn't, and the next thing she knew, she was transforming into a hideous bat monster every night and terrorising the populace...

The Vespera we know today isn't that "hideous bat monster", by the way. This is a halfway form that she permanently settled into after making a deal with the animal inside her. Spoilers... y'know, for the 0.0001% chance I actually write this story.
