Spawn / Batman #1 (Original 1994 release!)

IMAGE COMICS PRESENTS SPAWN / BATMAN
Frank Miller, author of The Dark Knight Returns, Batman: Year One, and Sin City, brings Batman to New York City in his search for an arsenal of high-tech weapons and robots that use decapitated human heads as their brains. Antagonistic, confrontational, and suspicious of each other, Spawn and Batman engage in violent battles before realizing they are both after the same villain. Begrudgingly, they decide to work together. The person they seek has been kidnapping and decapitating the homeless for use in the robots, but that's only part of the plan—there is also a nuclear arsenal ready to be deployed. Will Spawn and Batman be able to foil the plan to destroy the world? It's a story filled with many twists and turns and a surprise ending that affected Spawn for years afterward.
