The Mistress of Evil (KEL TU 035) is a comic published in 2015 on tumblr (and later on DeviantArt) by Kelly Green.
A portrait of the outlandish Mistress of Evil surrounded by small supernatural creatures.
“Rolly Crump’s ‘Mistress of Evil’ (well, with some liberties taken). Maybe she's Maleficent's eccentric cousin?”
“Not to be confused with the Mistress of All Evil. I've wanted to do an interpretation of this character for a while.”
