History
Professor Broom in his younger days was a skilled monster hunter and he enjoyed doing it. Eventually during the end of WWII, Broom and Lady Hatton were accompanying Lobster Johnson on the Island of Scotland were Nazis were experimenting with the occult. However, the Nazis summoned the demon creature from Hell and instead of killing it, Broom adopted it and nicknamed it Hellboy. Afterwards Broom was an honorary participant and a member of the Osiris Club on one of their "Wild Hunt" events in which the group slew giants.
