Two of comics' darkest characters cross paths again in the most anticipated comics event of the decade! Batman and Spawn are two vigilantes of the night who avenge the innocent by their own methods. When sinister forces manipulate the Dark Knight and the Hellspawn into confronting each other, you can bet that there'll be hell to pay when our heroes discover the truth and turn the tables on their would-be puppeteers.

An ancient evil has arisen in Gotham City. The last time it appeared, an entire colony was wiped clean from the face of the Earth, leaving only one clue: Croatoan. Whoever or whatever Croatoan is, it’ll take all of the Batman’s investigative skills and the supernatural abilities of an ex-soldier turned Hellspawn to save Gotham’s citizens from the hell that is about to be unleashed on our world.
