Hellboy: The Whittier Legacy #1

After Prof. Emile Stoop disappears, along with the bodies of three member of the Whittier Family and a skull once used by the family in occult rituals, Hellboy is brought in to find out what is going on. Hellboy enters a house to find Stoop standing over the three bodies and holding the skull. He tells Helboy that he is not really a Stoop, rather is real father was a Whittier. He then lights a candle and begins to contact the forces that the Whittier family used to. One of the dead men asks Hellboy if Stoop has the medallions they used for protection. Stoop becomes possessed by the creatures from beyond and begins to transform. Hellboy banishes the creature with one of the medallions, but Stoop dies in the process.
