Carly is a Super with shapeshifting powers known as Doppler.

Backstory
Carley was a normal girl that practically worshipped Supers, especially The Seven. One day, she got her hands on a syringe of Compound V and injected it into her arm. She then passed out and woke up the next day, now with black hair instead of blonde hair, though when she calms down, her hair goes back to being blonde. She realizes that she has the power to shapeshift, and she dubs herself as Doppler, The Shapeshifting Girl.
