The only creature of color that has appeared thus far, and she's only been in one episode: 1x07, "All Good Things..." Most viewers remember her walking down the stairs with Jasmine in the Colony House massacre, but she can also be seen from the upstairs window approaching the building with the other creatures, albeit briefly.

See? I encircled her so that she'd be easier to make out.

By the way, does anyone else think that this actress bears a striking resemblance to Raven Symone (A.K.A. Raven Baxter from That's So Raven)?
