Believe it or not... He's the good guy.

Hellboy, his pyrokinetic girlfriend, Liz, and aquatic empath, Abe Sapien, face their biggest battle when an underworld elven prince plans to reclaim Earth for his magical kindred. Tired of living in the shadow of humans, Prince Nuada tries to awaken an ancient force of killing machines, the all-powerful Golden Army, to clear the way for fantasy creatures to roam free. Only Hellboy can stop the dark prince and prevent humanity's annihilation.
In Hellboy II: The Golden Army, consciousness is carried by monsters and creatures — a plane of “mythic war”. The story fights on E8/E9/E11 of the E0–E14 reality ladder, compressing prejudice, identity, power, culture, conflict.
