Earth

The World is the world in which One-Punch Man takes place. The planet is similar to Earth in many aspects but also possesses some drastic differences from the real world.

Description
The World, unlike its real Earth counterpart, possesses a single super-continent instead of multiple large land masses. In the anime, it was shown to have four natural satellites instead of a single moon.

In addition to the supercontinent covering most of the planet, it possesses smaller islands and landmasses that float in its immense ocean.

The seven faced islands contain potatoes.
