Typhoid Mary

Mary Walker, a.k.a. Typhoid Mary (voiced by Alice Eve and Tara Strong) is a Marvel comics character that appears in Iron Fist and Avengers Assemble, she is an Inhuman with telekinesis, the ability to control minds and the ability to control fire. Similar to the Lizard, her villanous split personality is separate from her gentle, friendly and kind personality. As such, the benevolent Mary Walker transforms into the sinister Typhoid Mary against Walker's will, with the two personas fighting for control.
