A quiet and intimidating ghoul, Charon is Ahzrukhal's personal bodyguard and soldier. Every couple of days, Ahzrukhal sends Charon out to run some kind of errand. He always leaves packed with weaponry, and returns with a bag of caps. He's loyal to who ever holds his contract beyond question, and will do whatever his employer orders. Charon never sleeps - a strange trait even for a ghoul - and when he's in Underworld, he hangs out in the bar. There are rumors that he is unhappy with his position but can't leave Ahzrukhal's employ.
Although little is said about Charon's past, Ahzrukhal will tell you that he was raised by a group of people who brainwashed him into obeying whomever has his contract. Ahzrukhal insists that he isn't a slave, and implies that Charon did something in the past to deserve his "employment" with Ahzrukhal. While the terms of the contract are never shown, if you ask Charon to retrieve the G.E.C.K. in Vault 87, he says that he's only good for combat services, and that he's "nobody's errand boy."
The player can obtain Charon's contract by paying Ahzrukhal 2,000 or 1,000 caps (Barter 50), or by agreeing to kill Greta. Acquiring Charon's contract makes him a potential companion. Once he is no longer bound by honor to serve Ahzrukhal, Charon will kill him, because Ahzrukhal has "very evil" karma.
Charon follows a personal moral path. Stealing in Underworld results in him attacking the player. If the player kills a good non-player character in Charon's presence, Charon will become upset and, if subsequently fired, become hostile.
When his contract is purchased, Charon says he must "chat" with his former employer: he walks to the bar, speaks briefly to Ahzrukhal, then shoots and kills him. If questioned about it, Charon replies, "Ahzrukhal was an evil bastard."
Charon will join the player regardless of Karma.
Charon's employment contract in the Pip-Boy reads, "Note - A piece of paper with some writing on it."
Charon is about a foot taller than the Lone Wanderer and most human/ghoul non-player characters.
Charon cannot be recruited if Ahzrukhal is killed before his quest is completed, as Charon's contract can only be obtained through completion of the quest. Charon will simply tell you talk to Ahzrukhal, even if Ahzrukhal is dead.
Charon's combat shotgun has to be cocked exactly like a BB gun or lever-action rifle, and even has the same reload animation, although combat shotguns are semi-automatic and magazine fed.
Charon will be let into Tenpenny Tower with you before you even complete the Tenpenny Tower quest.
Charon is the only companion competent with explosives. If given standard grenades he will effectively use them when enemies are taking cover, in order to flush them out.
In Greek mythology, Charon (or Kharon) is the ferryman of Hades who carried souls of the newly deceased across the rivers Styx and Acheron, which divided the world of the living from the world of the dead.
Charon will occasionally remark that he finds happiness in a warm gun, alluding to a song called 'Happiness is a Warm Gun' by The Beatles.
pcps3xbox360 When buying Charon's contract from Ahzrukhal, a bug can occur during their interaction that leaves one, or both of them, unable to respond to the player (i.e. Charon will not follow you and/or Ahzrukhal will not talk to you). This bug may happen if Ahzrukhal is asleep. When Charon goes to wake him, Ahzrukhal will say his first line of dialog and Charon will stay in place. Ahzrukhal will then go to the area he is in originally when you walk in during the day. It can be solved on the PC by using the in-game console command "resurrect" to reset the problematic non-player characters. On the Xbox 360 this bug can sometimes be solved by exiting and re-entering the game. [verified]
This bug can be avoided altogether by simply waiting for Ahzrukhal to wake up before telling Charon you now own his contract.

If while cloaked you talk to him and give him power armor (possibly any armor) while he is cloaked and leave the trade equipment screen, he will put the power armor on and still be able to sneak allowing you to grab the now unequipped Chinese stealth armor and wear the Chinese stealth armor yourself.
