Prophet of Mercy (Movie)

Prophet of Mercy was a major antagonist in the Halo 2 movie. He was the oldest of the three Hierarchs that led the Covenant Empire.

Great Schism and Death
As he watched Truth deliver a speech upon the successful acquision of the Index, John-117 was teleported by the Gravemind directly into the Council Chambers. Upon noticing John, Mercy, Truth and a handful of Brute Honor Guards fled. Later, as the two Hierarchs were about to depart for Earth with the Forerunner Dreadnought to begin the Great Journey, a swarm of Flood Infection Forms attacked them.

A single Infection Form managed to evade the guards, latch onto Mercy's neck and began devouring his windpipe. Tartarus attempted to save him, though Truth intervened and allowed Mercy to die in order to become the sole leader of the Covenant. Before his death, he was found by John, who questioned where Truth was going. He answered that Truth is going to Earth to finish what was started. John then violently tore the Infection Form from Mercy's neck, killing the old Prophet instantly but saving him from being infected by the Flood.

Personality
Mercy can be passionate, wise and knowledgeable, showing excitement about Halo and expressed hope that the Great Journey would be very soon. He also has a sense of propriety and is perceptible and an authority on the Forerunners and their knowledge.
