Batman: Bloodstorm

He is becoming what he hates... Prowling the city's darkest corners, the Batman seeks to destroy an army of vampires before they can feast upon the innocent... and before he himself succumbs to the terrible thirst for human blood.In Elseworlds, heroes are taken from their usual settings and put into strange times and places - some that have existed, or might have existed, and others that can't, couldn't or shouldn't exist. The result is stories that make characters who are as familiar as yesterday seem as fresh as tomorrow.
