Mari McCabe is Vixen, a superhero who, with the Tantu Totem, can tap into the powers of any animal on Earth.
After being given the totem by a shaman, Vixen originally gained a reputation as a hero. However, she wasn't active during the five years of Superman's Regime.
Vixen later surfaced after Superman's defeat as a member of the League of Assassins, working with its leader Ra's al Ghul to organize a mass extinction of the human race in order to purify the world once more.
