Veteran actor teases fans on possible return in Halo Infinite. On December 30, Keith David teased fans on Twitter about the return of his character Arbiter. In his tweet, David jokingly replies to a fan asking if he’s in Halo Infinite by answering “i’d have to kill you” if he said that.
Although the character was missing from Halo 4, the Arbiter appeared for Halo 5: Guardians, closing out the game by joining forces with the Master Chief as Cortana takes a villainous turn. The conclusion of Halo 5: Guardians could be seen as setting up a reunion of the Master Chief with the Arbiter for the upcoming Infinite mission.
