Jericho (Fallout 3)

Jericho is a join-able NPC in Fallout 3, and is found in the town of Megaton. He wields a Chinese Assault Rifle. He also states that he has left the life of a raider in the Wasteland behind him, tired of the killing and violence. Jericho can become a companion with the Vault 101 Dweller, although the player must retain copious negative karma to do so. Jericho also requires that the Vault 101 Dweller pay him 1000 caps for supplies. He is generally effective in combat though putting him in dangerous situations will likely cause his death. If you choose to fire him he will return to Moriarty until required again though will not join unless you have a bad enough karma. If you talk to him some more he reveals that Moriarty hides his daily profits from his saloon in a footlocker at his bed, and that he wears the key around his neck. If you nuked megaton, jericho will still wait there if you fire him. He can also wear power armour.
