Appearances
Seraphs are never seen in action in the games, although they are often mentioned in the novels. The only time a Seraph is seen at all in the games is in Halo 2, on the levels The Arbiter and The Oracle, where one is seen in a hangar in a Forerunner facility in Threshold, which the Covenant storms in an attack on the Heretics. The Heretic Leader attempts to escape the storm on Threshold in the Seraph, but is successfully stopped by the Arbiter, who slays him in combat.
