Heretic Elite Majors are denoted by their golden armor. They served as commanders to the Minors and the Heretic Unggoy. They also guard places as designated by the Heretics leader, Sesa 'Refumee.
They are fearless warriors that ensure that their jobs are done well. They were enemies in the levels The Arbiter and The Oracle. However, the High Prophets sent in squads of Special Operations Elites and Grunts, accompanied by the Arbiter, to quell the heresy and the group infiltrated the mine and completed their objective. Most of, if not all, the Majors were killed when the gas mine fell into the depths of Threshold, after the Arbiter cut the cables holding the mine up.
- They are one of the least seen bipeds in the Halo trilogy, as they only appear on two levels; The Arbiter and The Oracle in Halo 2.
- Their shields are about as strong as a Sangheili Major.
