Panky

Detail of her shirt can be downloaded here. (I didn't draw it, I found that picture on Google)

Due to her being very old, her powers have become a bit weak and she gotta use them carefully. That's why she also keeps her demon wings usually hidden, as you can clearly tell she's old because of how rotten and broken they are.

Her eyes may turn redish when she gets really angry or excited.

She's Callie's cousin.

Though Panky is such a bad-ass she also has a tender side, that's why she created her Alter Ego: Patryce
