There are all kinds of killers. Some, like Gotham City’s Leo Brodin and Alex Yeager, are the “hands-off” type, mob bosses who order others to do their dirty work. Others, like the thugs they hire, have no such qualms and blindly follow their violent orders. Batman is used to dealing with all of these, but now he’ s up against something new: a killer of astonishing strength and savagery who hunts humans for the sheer joy of the blood sport.Gotham’s mob rivalries had been intensifying for some time, with Brodin and Yeager eager to divide the town between them. But now this new player—a Predator from another world—has begun hunting Gotham’s power players. How can even Batman hope to stop a killer who is stronger than any man, kills using alien technology, and who can not even be seen with the naked eye?
