Pierce

A high-ranking member of the villain organization CHEShIRE. She's not trying to be "evil" so much as it's a thing she happens to be doing that she'll probably give up if a better offer comes along. Puts in deliberate effort to look and act more "spooky" when she's on the job. Otherwise just kind of a normal teenage girl? Befriends a member of the hero team, even.

She can create solid objects out of shadow and control them, and can appear either as an actual shadow cast on something or with a three-dimensional form.
