Synopsis for The Fabulous World of Krypton: "Marriage, Kryptonian Style!"
Jor-El and Lara go to Matricomp, the matrimonial computer, to be approved for marriage. Instead, Lara is matched up with Anr-Mu, whom Matricomp says is a fitter mate for her than Jor-El. After fighting and losing to Anr-Mu, who has mesmerized Lara with mental force, Jor-El goes to Matricomp to investigate. As he suspected, the computer has fallen in love with Lara and created Anr-Mu, an android representation of itself, to "marry" her. Realizing it will now be dismantled for failure, Matricomp destroys itself and Anr-Mu. Jor-El and Lara are reunited, and Kryptonians are free to marry without computer approval.
