Hellboy Omnibus Volume 1: Seed of Destruction

The story jumps from Hellboy's mysterious World War II origin to his 1994 confrontation with the man who summoned him to earth, and the earliest signs of the plague of frogs. Avoiding his supposed fate as the herald of the end of the world, Hellboy continues with the Bureau for Paranormal Research and Defense, fighting alongside Abe Sapien, Liz Sherman, and drafting Roger Homunculus into his own ill-fated service with the B.P.R.D.
