Keith David

The Arbiter is a playable character from the Halo science fiction universe, first voiced by Keith David in the 2004 video game Halo 2. A different Arbiter appears in the 2009 real-time strategy game Halo Wars, voiced by David Sobolov. Although the Arbiter is intended to die serving the High Prophets, he survives his missions and the Prophets' subsequent betrayal of his kind. When he learns that the Prophets' plans would doom all sentient life in the galaxy to extinction, he allies with the Covenant's enemies—humanity—to stop the Halo from being activated. The entertainment website IGN lamented the loss of the Arbiter's storyline in Halo 3, but the Arbiter character was not evenly received by critics and fans, nor was the humanization of the Covenant in general. The character's name was changed from "Dervish" to avoid reinforcing a perceived US-versus-Islam allegory in the game's plot. (Full article...)
