The Covenant is an evolved species of aliens on the outer rim of the Milky Way Galaxy. The head prophets, who preach of the great journey to fire the Halo Rings, rule them. The Covenant have many different types of foot soldiers from small Grunts to big armored Hunters. They have elites, foot soldiers the size of a Spartan, who are their main foot soldier in the first two Halo games. Their weapons are plasma-based, and most overheat if shot to long. They have everything in their arsenal to match the UNSC from big tanks to fast land vehicles. The Arbiter is an elite chosen by the prophets to command. The prophets choose Brutes, armored gorilla-like soldiers to command the Covenant army. Because of this the Arbiter and other members of the Covenant broke away from the Covenant. The separatists help the UNSC in Halo 3. The Covenant technology is better than the UNSC’s but they can’t stop Master Chief.
