Space

Space or outer space is the vast and empty area outside Earth's atmosphere. It includes planets, stars, galaxies and everything in existence of the One-Punch Man universe.

In order to find a worthy opponent that could give him a challenging fight, Lord Boros and the Dark Matter Thieves led by him travelled through space for many years via the giant spaceship. For that reason, Boros was known as the Dominator of the Universe. From an unknown place in the universe, it took Boros and his crew 20 years travelling through space to finally arrive on the planet Earth.
