You may have thought Jason Blood was a man possessed by Etrigan the Demon, but BLOOD OF THE DEMON — the new ongoing monthly series written by John Byrne & Will Pfeifer (AQUAMAN, H-E-R-O) with art by Byrne & Bud LaRosa — reveals a whole lot more about their “blood bond” than anyone ever realized!

Etrigan is on a rampage in Gotham City, where a nameless villain needs him to open a portal to another dimension…and will torture Jason Blood endlessly to make Etrigan his slave!

All the rules have changed! Expect pandemonium and mayhem as Etrigan, loyal to no one, takes on otherworldly foes in the first battle of an all-out war!
