Superman/Batman: Public Enemies

Lex Luthor is elected President during a severe nationwide economic depression. Under his leadership, the economy begins to thrive, and he assembles a group of government-employed superheroes consisting of Captain Atom, Katana, Black Lightning, Power Girl, Starfire, and Major Force. Despite Power Girl's enthusiasm about the peace and stability and Atom's loyalty to the government, Superman and Batman maintain their distrust toward Luthor. The United States government discovers a massive Kryptonite meteor hurtling toward Earth. Instead of asking superheroes for aid, Luthor decides to destroy it with nuclear missiles. Luthor arranges a meeting with Superman in Gotham City under the pretense of a truce, only to result in a battle with the hired Metallo against Superman and Batman, in which Metallo manages to injure them both before an unknown assailant kills him. On national television, Luthor pins Metallo's murder on Superman, using altered footage of their battle to implicate him as well as a baseless claim that Kryptonite radiation can affect Superman's judgment, then places a billion-dollar bounty on Superman. Batman and Superman break into S.T.A.R. Labs seeking information on the meteor, and find Metallo's remains; they realize that a radioactive energy blast killed him, and it was made to look like Superman's heat vision. An army of villains looking to collect the bounty attacks them. Superman and Batman easily overpower most of the villains while Captain Atom defeats the rest with a giant energy blast. All of Luthor's superhero team except Power Girl, whose loyalties are divided, attempt to capture the heroic duo until Superman creates a twister using his super-speed, and the two heroes escape with Power Girl. In Metropolis, Power Girl admits that she does not believe Superman killed Metallo and dislikes Luthor. Luthor's superheroes catch up and the fight begins anew with Power Girl aiding Batman and Superman until Batman deduces that Major Force killed Metallo under Luthor's orders and goads him into admitting it in front of everyone. When Major Force snaps and tries to kill him, an angry Power Girl punches him hard enough to rupture his containment suit, releasing his radiation. Captain Atom absorbs the energy, disintegrating Major Force and leaving him comatose. Meanwhile, the missiles fail due to the meteor's radiation destroying them before impact. Amanda Waller discovers that Luthor has secretly been taking a serum composed of a strength-enhancing steroid and liquid Kryptonite. Luthor then informs Waller that he will let the meteor hit Earth as he plans to rebuild society in his image, becoming Earth's single leader. Batman and Superman battle Captain Marvel and Hawkman before breaking into Luthor's base of operations to retrieve data on the meteor. Luthor refuses to relinquish the data, going so far as to erase it from the lab computers, but Waller gives them a copy. Batman, Superman, and Power Girl head to Tokyo to deliver the data to Toyman, who has already built a rocket-propelled spacecraft to stop the meteor. Waller and the military then attempt to arrest Luthor, but he injects himself with more Kryptonite steroids and dons a power suit equipped with Kryptonite weaponry. After escaping Waller and the military, Luthor follows Superman and Batman overseas, intending to kill Superman himself. After Batman and Superman arrive at Toyman's lab, he shows them the spacecraft, which resembles a giant, robot composite version of Superman and Batman, and with the data creates reinforcements so that it will not explode before impact. However, Luthor arrives and neutralizes Power Girl, Superman, and Batman, and disables the rocket's remote guidance systems so that it will not take off by itself. With no other choice left, Batman decides to fly the rocket himself despite Superman's protests. Though initially faring poorly, Superman eventually disables Luthor's suit, and he is apprehended by Captain Atom and his team. Batman successfully destroys the meteor and returns to Earth in an escape pod. With the truth of Metallo's death now public knowledge, Superman is cleared of murder charges, while Luthor is arrested and taken to face trial and impeachment for his crimes. Batman returns to Gotham while the Daily Planet's star journalist, Lois Lane, arrives and embraces Superman.
