The Space Lex Earth Saver is a giant ray gun created by LexCorp.
Background[]
The machine was supposedly designed to fix the Ozone. In reality it was a Doomsday device that was made for Lex Luthor's plan to blot out the sun. Not only would this render Superman powerless, but Luthor planned to allow anyone who could afford it to relocate to his moon base in order to escape the apocalypse.

Luthor plans to thicken the ozone layer, but when the laser he used on the Moon proves to be too short to reach Earth's atmosphere, he decides to avail Volcana's powers. Nora Freeze who did not trust Luthor after the whole Jon incident, refused to let this happen, so Luthor traps her, Volcana, King Shark, and Captain Cold inside the Hall of Doom. When he attempts to gas the building to force them out, they create an explosion to escape. However, the heat magnifies the atmosphere enough that Luthor can use his laser and block the Sun.
