She-Bat (Batman, New 52 universe)

[sodacat]

Just thought I'd mention something else I've been researching recently: One of Wonder Woman's villains, and her main non-greek villain post-nu52, is Cheeta, a homicidal woman imbued with the power of a hunter god. The first two versions of Cheeta were just women in costumes, but the current one is a full on cat-girl. Around the year 2000 another god gave her the ability to magically disguise herself as human, and a little time after that she gained the ability to actually change between human and cat at will. I haven't found any on-panel changes yet, though.

In the Nu52 she's ditched her human persona entirely, so that's unlikely to come up again.
