Aviva

Aviva was a teenage girl who was corrupted by the priestess Kali. She was a good witch invulnerable to Pipers molecular immobilization power. She displayed fire starting abilities, along with possibly pyrokinetic abilities through touchable combustion.

Originally coerced by Kali into infiltrating the Halliwell coven upon forging a friendship with Phoebe she turned on Kali relinquishing her powers, Kali possessed her and was defeated by the Charmed Ones presumably leaving Aviva powerless and able to go on with her normal life.
