That's Megalyn Echikunwoke as the live action iteration of Mari McCabe, better known around these parts as Vixen. First appearing on CW Seed's digital animated series of the same name, Vixen will be appearing in live action for the very first time this year on Arrow.
A street smart model who inherits a mysterious family heirloom that grants her the powers of the animal kingdom, Mari first met Green Arrow and the Flash during the debut season of her series, but fans won't have to wait until the second season of Vixen debuts to see her reunite with at least one half of that superheroic duo. Look for Vixen to appear in the Episode 15 of Arrow, which is entitled "Taken."
Miss out on the animated Vixen? Well, you can now check out the entire first season, which has been edited into one single 30-minute episode on CW Seed.
