WildC.A.T.s / Cyberforce: Killer Instinct

From 2004, DC published this one-shot crossover uniting Jim Lee's two creator-owned teams—the espionage-oriented WildC.A.T.s and the cybernetically enhanced Cyberforce—for a single, action-packed encounter. Written by Brandon Choi and Jim Lee, with Lee also on art, the issue pits the squads against a common threat that tests their contrasting philosophies and powers. A brief but notable meeting of Image-era icons under the DC umbrella, it stands as a curio for fans of Lee's early-1990s creations.
