Despite his unthreatening appearance, Barney was a sadistic murderer and an auctioneer of body parts of demons and other empowered beings. Barney sought the help of Angel Investigations when he was being tracked down by a demon hunter, who turned out to be Wesley Wyndam-Pryce, who was actually tracking a Kungai demon, who Wesley believed was responsible for a number of deaths that had actually been caused by Barney himself: in reality the Kungai was merely tracking Barney in order to exact revenge for the removal of his Tak horn (which resigned the demon to a slow and painful death).
