At some point in the past, this demon possessed Singer Salvage Yard owner Bobby Singer's wife Karen Singer for an unknown reason. The demon proceeded to attack Bobby who didn't know about demons and simply believed that his wife had gone crazy. In desperation, Bobby attempted to fight off his possessed wife by stabbing her repeatedly. However, the stab wounds had no effect on the demon who continued the attack until hunter Rufus Turner arrived. Rufus soaked the demon in holy water and exorcised it back to Hell. However, the injuries Bobby inflicted upon Karen were fatal and she died afterwards. In the aftermath, Rufus helped Bobby clean up the mess and Bobby, now knowing what was out there, became a hunter himself.
Years later, when trapped in a nightmare by Jeremy Frost, Bobby's nightmare included his dead wife attacking him in anger over his inability to save her from the demon. This was witnessed by Dean Winchester who had entered Bobby's dream to save him. Afterwards, Dean asked Bobby if it really happened and Bobby told him that "everyone got into hunting somehow."
In 2011, following the death of Rufus, Bobby tells the Winchesters about how Rufus had saved him from the demon which led to them hunting together for years.
