Before he died and landed in the depths of the Hells, Hellboy travelled extensively, either as a member of the B.P.R.D. or solo. In 1956, he investigated a series of murders in Mexico... and disappeared for five months. He then declared that he did not remember anything. Yet, vampire hunters, an Aztec mummy, witches and ghosts... and Frankenstein's monster crossed his path.
