Prophet of Regret

Regret is one of the three Prophet Hirearchs, and is the youngest of the three. He is very reckless and stupid, the only thing that makes him in any way bearable is that he loves Elites, and so is automatically the cleverest of the three Prophet Hirearchs. He commands the Solemn Penance, a Covenant Ship doomed to failure.

He has an unneccesesarily high-pitched, camp voice, and seems to have little control over his throne. In fact, merely firing the plasma cannons on the front makes him fly backwards. He also has no control over where the throne takes him, as shown in his short fight against Johnny, in which he flies straight into Johnny and allows him to board the throne before teleporting away.

He fought against the Spirit of Fire when it landed on the Flood-controlled Shield World, but failed as usual due to the crappy Brute Chieftain who came with him. Regret originally had a great ally to help him, an Arbiter in fact, but he was killed by Sergeant Forge and as soon as the Chieftain took over the Covenant Army was decimated. Regret fled the Shield World, desiring revenge.

Regret's next failure was when he arrived at Earth thinking it was a Forerunner Relic deposit (i.e. Bin) and his fleet was utterly annihilated by Hood and the idiots at Cairo Station. Only the Solemn Penance made it out alive, only to happen upon Halo Installation 05. Regret landed on the ring and went to a random temple, singing in a strange language on the comms all the way. Eventually Johnny got so annoyed with the singing that he took the trouble to go all the way to the temple just to beat Regret's voicebox apart, killing him in the process.

Regret was then assimilated into the Gravemind, a dubious honour, and was doomed to have endless philosophical arguements with 2401 Penitent Tangent for the rest of eternity.

Regret is undoubtedly a large failure. Despite his one talent (being able to sing in Covenant language in such a way that it can be translated into perfect English), both Truth and Mercy hate him, but they kick up a fuss when he dies because they want the Brutes to be elevated into the Covenant, thus proving their stupidity.
