Mr. Xavier

Mr. Xavier

Alias of an alien mercenary agent (Xviar) sent to Earth from "Homeworld" to observe Kal-El's life and to prepare the way for using Superman as an instrument for the planet's destruction. As part of this end, he arrives on Earth as Kal lands and follows him for 30 years, including moving into the apartment next to Clark Kent.

Manipulating Superman's perceptions of his powers by treating his clothing with a chemical that blocks yellow sun radiation, Xavier also uses intruments in the apartment to communicate telepathically with Superman and to transform into an explosive instrument. Space jewels in Clark's possession are employed to summon nine of the most fearsome foes Superman has ever faced to Earth, so that Superman's fights with them feeds the process for him to become the bomb that destroys the planet.

Superman finally figures out the scheme, part of a contract "Homeword" has to clear the Earth for an intergalalctic teleportation route, and he also foils Xavier's attempt to escape the solar system by posing as one of the foes Superman has defeated (Amalak).
