Brainiac

As Clark Kent discusses his future as a reporter at the Daily Planet with his boss, Perry White, Metropolis is suddenly attacked by a robot from outer space, which begins wreaking havoc on the streets while scanning the people and environment. Clark suits up as Superman and manages to destroy the robot, but not before it identifies him as a Kryptonian and informs its creator, Brainiac (modeled after actor Yul Brynner), an exterrastrial cyborg from the planet Colu who is the last of his kind and obsessed with preserving life and cultures. Superman takes the head of the robot and gives it to Lex Luthor (who was recently released on parole) to analyze.

While discussing the robot with Lois Lane, Clark notices a large spaceship approaching the city. Brainiac arrives and demands Metropolis to hand Superman over to him, believing his presence is endangering Earth's ecosystem. Superman fends off the robots, but ultimately surrenders when Brainiac threatens to destroy the city. After taking him into his ship, Brainiac shrinks Clark and places him in the bottle city of Kandor, the last remains of Krypton that was preserved before the planet's destruction, where he discovers that a portion of Kryptonians survived, including his birth parents, Jor-El and Lara. Clark agrees to succeed his father as leader of Krypton's council affairs, but has a hard time adapting to the new environment.

On Earth, Lex brings Lois into his secret hideout and reveals he planted a receiver on Superman before Brainiac took him. He allows Lois to use his space transmitter to communicate with Superman, which Brainiac is quickly alerted to. Lex reveals his plan was for Brainiac to intercept the transmission so he could challenge the alien's intellect. However, it instead encourages Brainiac to excise Metropolis and shrink it to preserve it like he's done for the other civilizations, leading Lex to flee in a hot air balloon.

Jor-El finds the receiver on Superman's suit and realizes he can modify it to help Clark return to normal size and escape from the bottle. Despite Lara's protests, Clark agrees to the procedure so he can save Metropolis and Kandor. After returning to the ship and regaining his powers, Superman faces off against Brainiac and his legion of robots. He defeats the cyborg and retrieves all of the bottled civilizations before the core of the ship explodes, destroying Brainiac and his backup models. Metropolis begins plummeting back to the ground, but Superman helps the city land safely.

Clark begins working on follow-up stories of the incident with Lois at the Daily Planet. He briefly stops by the Fortress of Solitude to talk with his parents, vowing to find a way to free them and the rest of the civilizations Brainiac had in his possession.^[3]

The Metal Curtain

One night near the city's docks, Lois attempts to secretly record the U.S. Army's Colonel Evers engaging in an illegal arms sale. Evers captures her and destroys her recording before sending her in a boat to crash into a nearby barge, but Superman manages to save her in time and repair the ship. The next day, Perry refuses to run her story without other official sources. Unbeknownst to them, Evers is actually General Morosov of the Soviet Union. In Moscow, Morosov meets up with Captain Nikolaev, a dedicated and well-regarded Soviet soldier. He reveals to the young captain that the Soviet Union came into possession of Superman's weakness, kryptonite, in the early 1950s shortly after Krypton's destruction and now have developed an enhanced armor to harness the kryptonite's power for themselves. Believing that defeating Superman will demonstrate their might to the world, Morosov offers Nikolaev the chance to become the ultimate Soviet soldier that they will call "Metallo".

Superman flies Lois to the Fortress of Solitude for an interview and for the chance for her to meet his parents, still miniaturized in the city of Kandor. As Lois talks with Jor-El and Lara, Clark prepares to reveal his secret identity to her once more. Before he can do so, he hears an American spy plane getting attacked in the skies above the Bering Sea and leaves to rescue the pilot, codenamed Highball. After helping Highball to safety, Superman is attacked by Metallo, who uses his kryptonite armor to sap his strength and brutally beat him down. Declaring himself the new Superman, Nikolaev exposes the hero to his kryptonite chest and leaves him to die in the sea.

In Moscow, Morosov reprimands Metallo for attacking Superman and revealing their power to the American military too soon. Highball saves Superman from drowning before the two are picked up by the U.S. Navy's General Sam Lane, Lois' father. Learning of Metallo's attack and of the threat the Soviets pose, Lane encourages Superman to stay out of this conflict as the Man of Steel returns to the Fortress to bring Lois back to Metropolis. Perry assigns Lois to cover Metallo's attack on the spy plane after she claims she has Superman as a source, but secretly contacts her father before publishing the story. Lex reads the story the next day and decides to investigate further.^[4]
