Ghost Professor Broom, or just simply Ghost Broom, or Ghost Bruttenholm, is a minor character in Hellboy VS Demonic Toys. He is the spirit of Professor Trevor Bruttenholm. He is also the second ghost to emerge from the portal (other being Ghost Manning) that unleashes souls from Heaven. Once Kurtz and The Demon King were stopped, the portal to Hell was reversed to a portal to Heaven.
Bruttenholm was killed by Karl Ruprecht Kroenen, who stabbed him in the head.
