Superman: The Earth Stealers #1
The Man of Steel must find a way to free planet Earth from the clutches of aliens from outer space.
This story is pure 80’s cheese, as only John Byrne could do at the time, with a group of space men on the moon witnessing aliens steal the “earth moon system” to feed it into a remote world eating furnace to fuel an alien civilization that’s just barely holding on. Of course Superman being so super was able to save all of humanity by using his wits, strength, and the power of friendship.
After everyone got back home they agreed to just not talk about how Earth was stolen and that no one really needed to know that even happened.
