This will be my own take on hellboy let me be clear I dont have access to his comics so i havent really read them I have seen all the movies at least for live action
this will be inspired by that verson of hellboy (not a huge fan of the reboot)
in this version hellboy is the son of Trogon an a powerfull unknown demon
during world war 2 he was summoned into the world
hes was taken in by the U.S forces witch would
soon form the paranormal investigation bureau
however many years in the future hellboy is alone an must work with new heros to save his sister rachel roth aka raven
