10 Shockingly Dark Origins Of Comic Book Heroes

10. Jason Blood/Etrigan

Jason was a simple farmer with a wife and children when Merlin bound him to his half-brother, the demon Etrigan, at the fall of Camelot. The blending of two souls and minds in one body created temporary insanity in Jason’s mind. The resulting two-day massacre earned the host his new last name, Blood.

An insane mind was of no use to Etrigan, so he tweaked his host's mind to be more in line with his plans. Through the centuries, The Demon cut a path of destruction while making Blood rich and powerful. They fought through the Crusades, wiped out Native Americans in the New World, and played both sides of the Civil War. In WWII, Jason called forth the beast to wipe out German forces but the depth of the carnage would have driven the man mad had Etrigan not blocked his memory. However, The Demon botched the spell and wiped all his memories.

Having settled in Gotham and become a demonologist, Jason Blood discovered a spell that released the Demon again. Jason had some control over Etrigan this time and was able to at least “point” the Demon where his specific type of rhyming destruction could do the best. Etrigan, and by association, Blood has worked with a number of mystical and magic-based heroes in the current century.
