it into a town celebration. Gus and Vera, disguised as Army officers, give Superman the flawed Kryptonite as an award. Although it has no immediate effect, Superman becomes selfish, and then commits petty acts of vandalism such as straightening the Leaning Tower of Pisa and blowing out the Olympic Flame. Gus asks Webster to build the world's most sophisticated supercomputer; the CEO agrees, if Gus creates an energy crisis by directing all oil tankers to the middle of the Atlantic Ocean. When the captain of one tanker insists on maintaining his original course, Lorelei seduces Superman, persuading him to waylay the tanker and breach its double hull, causing an oil spill. The villains decamp to the supercomputer's location in Glen Canyon. Superman suffers a nervous breakdown and splits into two beings: the immoral, corrupted dark Superman and the moral, mild-mannered Clark Kent. The two fight in a junkyard, with Clark eventually defeating his evil self. Regaining his sanity, Superman repairs the damage he caused in the oil spill and heads west to deal with the villains. After defending himself from exploding rockets and an ASALM missile, Superman confronts Webster, Vera, and Lorelei. The supercomputer identifies Superman's weakness and unleashes a beam of pure Kryptonite. Guilt-ridden and horrified by the notion of "going down in history as the man who killed Superman", Gus destroys the Kryptonite ray with a firefighter's axe. Superman escapes, but the computer becomes self-aware, defending itself against Gus's attempts to disable it. The computer transforms Vera into a cyborg that attacks her brother and Lorelei with beams of energy that immobilize them. Superman returns with beltric acid, which the supercomputer believes is not dangerous. The intense heat emitted by the supercomputer causes the acid to become volatile, destroying it. Superman leaves Webster and his cronies for the authorities, but thanks Gus for saving his life. The pair fly off to a coal mine where Superman transforms coal into a diamond for Lana. Gus declines to return to Metropolis, deciding to make a fresh start in West Virginia. As Clark, Superman visits Lana after she moves to Metropolis. A drunken Brad attacks Clark believing he was proposing to her, but the reporter defeats him without revealing his secret identity. Lana's new job as Perry White's secretary surprises Lois Lane, who returns from her vacation with an article about corruption in Bermuda, and has a newfound respect for Clark
