Hellboy, a half-demon living in a world that fears him, continues to struggle with his destiny as a harbinger of the apocalypse. Several monsters have now told him that his hand is the key that will free the dragon from its prison deep in the abyss where it was banished. Despite his monstrous appearance, Hellboy yearns for acceptance and fights to protect humanity from those who wish to inflict evil or to destroy the world. 

Returning to England, Hellboy and Abe track down a demon that was released on purpose. When they confront that demon, Hellboy learns his true name, Anuug Un Rama. Hellboy returns to America where he inquires about Roger's progress in integrating in the human world. Hellboy rescued Roger, the homunculus in Hellboy Omnibus, Volume 1. Roger is in good enough shape to go on a mission, and the Bureau for Paranormal Research and Defense sends them both to an ancient Nazi site in Austria, where a rocket launched by the Third Reich is returning to Earth. There they face the evil Nazi doctor Herman von Klempt, who was there when the rocket was sent to space, and who is bringing back a worm so strong it will consume the entire Earth. Unfortunately for the Doctor, Roger uses his electrical conduit ability, and neutralizes the worm, and the Doctor is finally destroyed.

But Hellboy faces an identity crisis. The Bureau for Paranormal Research and Defense equipped Roger with a bomb, so that Hellboy could destroy him if he started causing problems. Questioning the morality of that decision, Hellboy turns in his resignation and heads to Africa, where he encounters a mystic that guides him through encounters with dark forces, so that he can discover himself ...
