she is a magician! all for fun, of course, none of the tricks are real, it's all fake, don't worry
she can magically enhance her own body to make herself stronk, and her face can take a few different forms (it's a mask, so she can change that out-- she also has a face under the mask)

her feet can be drawn like bird feet or sort of how they are now, which is i guess also bird feet

she also has a long cat tail
