Prophet

Prophets are the leadership caste within the Covenant, and one of the more mysterious members of the Covenant.

Summary
Little to nothing is known about the Prophets, beyond the fact that they are the sole members of the leadership caste of the Covenant hierarchy. They are an integral part of the Covenant High Council, formerly sharing this responsibility with the Elites. However, the expulsion of the Elites and their replacement by the Brutes is likely to have caused a power vacuum, and it is not known if any Brute councillors exist, or if the Council still exists, with the loss of the Covenant capitol city, High Charity.

Prophets appear extremely frail - either as an adaptation to a low-gravity world, or because of age. They have lobes of skin underneath their chin similar to a beard, and elderly Prophets have skin lobes on either side of their heads, like ears. These are covered in a thin fuzz. Prophets also have only three digits for their hands, and usually wear ornamental pieces that also double as life support mechanisms These head-pieces bear a holographic representation of Halo, but each is uniquely shaped and ornamental.

It is known that they claim to have evolved on a former colony of an ancient race called the Forerunners, which the Covenant reveres as their gods, earning the species their name. It is also known that they waged a fierce and bloody war against the Elites at some point, halted only by the discovery of Forerunner artefacts near the field of battle. The two races united to learn their secrets, forming a mutually beneficial arrangement that would eventually become the Covenant. The Elites would become the protectors of the Prophets, in exchange for which the Prophets would dedicate themselves to studying the Forerunners and learning the method of their "ascension".

As the representatives of the gods, the Prophets hold a great amount of power over the other races of the Covenant, earning reverential monikers such as "Holy One" and "Eminence". They are protected at all times by Legions of Honor Guards, and rarely involve themselves in combat, preferring to dedicate themselves to studying Forerunner artefacts. However, important events to the Covenant usually require a high-ranking Prophet, such as a Hierarch, to be present.

The majority of the Prophets use anti-gravity belts to support themselves. Higher ranking Prophets, such as the Hierarchs (a group of three Prophets with total control of the Covenant), use anti-gravity thrones to support themselves. These, however, are not so much for support than for personal defence - they are fitted with holographic emitters, an energy shield generator, and a built-in Fuel Rod Cannon, and in the event of assasins getting past their guards they are able to defend themselves quite well.

Appearances
The only Prophet that you fight is Regret. He appears at the level called Regret. There other appearances, though. In most of the cinematic sequences in Halo 2, there is at least one Prophet present. And besides that, Mercy's corpse is found at the beginning of the level called High Charity.

Flood Prophet Form
Prophet Form is a term to describe Covenant Prophets that have been infected by the Flood. Due to their unusual nature, they are not thought of as Combat Forms in the way infected Humans and Elites are (Note that the term "Prophet Form" has not been officially used as canon to date). It is also worth noting that both "prophet forms" seen had only just been infected, and may not have been assimilated in the conventional way. Prophet of Mercy was the only prophet to be seen being taken down by an infection form and the result of his infection was never shown.

Biblical Reference
Revelation 11:5-10

5. And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed.

6. These have power to shut heaven, that it rain not in the days of their prophecy: and have power over the waters to turn them to blood, and to smite the earth with plagues, as often as they will.

7. And when they shall have finished their testimony, the beast that ascendeth out of the bottomless pit shall make [war against them, and shall overcome them, and kill them.

8. And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified.

9. And they of the people and kindreds and tongues and nations shall see their bodies three days and an half, and shall not suffer their dead bodies to be put in graves.

10. And they that dwell upon the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets tormented them that dwelt on the earth.

this excerpt from Revelations bears similarities with the Flood attack on High Charity, but more importantly describes the death of two prophets (ie; Mercy and Regret), and their tyranny over their subjects before their deaths.

Trivia

 * In Halo: First Strike the Prophets (specifically Truth) appear to have telekinetic powers, although it maybe an illusion based on gravity manipulation technology.
 * The High Prophet of Mercy is named Hod Rumnt.
 * They must breath oxygen (or nitrogen) because Regret bleeds red blood when you melee him. The red colour of blood is caused by the reaction of iron in the bloodstream with oxygen. On the other hand, it is not known if it is even blood~
 * The Prophets appear to be biblical references, from Revelations 11:5-10
