Godzilla vs. Mechagodzilla
Black Hole Planet 3 is the home world of the Black Hole Planet 3 aliens, also known as the Simians, who first appeared in the 1974 film "Godzilla vs. Mechagodzilla". A planet in orbit around a black hole, Black Hole Planet 3's days were numbered, so its aliens launched a full-scale invasion of Earth with Mechagodzilla to take the planet as their own.
