Charon (Fallout 3)

Charon is a possible ghoul companion NPC in Fallout 3. Brainwashed as a child he is blindly loyal to the holder of his contract.

He resides in the Underworld as a bar bouncer. He can be hired for a sum of 2,000 credits, and will loyally follow you after that. You can also retrieve his contract from his employer, by killing Gretha in The Ninth Circle. His very first act as your new employee will be to have a "chat" with his former employer.

By default he uses a shotgun for his weapon, which appears to have infinite ammo as well as infinite durability, but this shotgun cannot be interacted with in any way. You can equip him with new armor and weapons which he'll happily wear. However, new weapons given to him do not have unlimited ammo so you'll have to keep an eye on his supply. His equipped gear appears to degrade with usage just like any other piece of gear.

One very interesting thing is that he knows how to use power armor. If you managed to acquire a suit of power armor early on but are unable to equip it yourself, give it to Charon.

Charon also appears to have health regeneration as a passive ability. Damage taken during a fight vanishes after a short time, usually before the next group of hostiles are encountered.
