Griffon is a huckster, a conman, a snake oil salesman. His current scheme is purchasing Aqua Pura, and stashing the water to sell to humans the Brotherhood isn't giving it to (raiders, slavers, Outcasts, etc.). He then puts regular irradiated water in the Aqua Pura bottles, and sells it to ghouls in Underworld as "Aqua Cura," claiming it reverses the ghoul condition. He wears a wig he found in the Museum Authority stock room, and for a ghoul, looks pretty healthy (just a coincidence, but helps make it seem like he's selling the real deal).
Griffon can be killed by an angry mob if the player character chooses certain paths in The Amazing Aqua Cura! quest. If he somehow manages to defeat the mob, he will exit out the museum front door and will permanently disappear from the game.
