An alien named TheMaster plots to take over the galaxy, and Franchise/{{Superman}} must join forces with his worst enemy and childhood friend SelfDemonstrating/LexLuthor to stop him.

A 1970s ''Franchise/{{Superman}}'' novel by Creator/ElliotSMaggin. It was originally proposed as the idea for a Superman movie, and the novel was released as a companion to the first Superman movie - although the plot and characterization (especially that of Luthor) differ greatly from the movie. (Even the location of Krypton is different; in the movie, Superman claims he comes from another galaxy, while in this novel Krypton is said to have orbited Antares.)

As this novel was written prior to ''ComicBook/CrisisOnInfiniteEarths'', Superman's powers reach near-ridiculous levels at some points. He flies through the core of the sun to take a refreshing bath. He fires a blast of air between his front teeth that disables a helicopter several blocks away, yet doesn't even affect anything else nearby. He takes out an entire mob of Lex Luthor's goons, one man at a time and in a different and inventively nonlethal way with each man, before a ten-second countdown finishes. It doesn't quite reach the truly insane levels shown in some episodes of the ''WesternAnimation/SuperFriends'' ("With Colossus distracted, I'll pick the Earth out of his pocket and put it back in orbit around the sun"), but it comes close.

There's also a sequel called ''MiracleMonday''.
