Mars

One universe's inhabited version of the planet Mars. (COMIC: On Earth)

Mars was, in some universes, the fourth planet from the sun in the Solar System. (COMIC: On Earth)

In one universe, it was inhabited by humanoid beings outwardly identical to humans, known simply as Martians. (COMIC: Magician From Mars…) It had two moons, Phobos and Deimos, whose names respectively meant “Flight” and “Fear”. (COMIC: On Earth) At some point in the future of the 20th century, there was regular contact between Earth and Mars. (COMIC: Magician From Mars…)

In other universes, Mars was inhabited by octopus-like beings who made war on humanity using Tripods. (COMIC: Miss Adventure, PROSE: The Grand Multiverse Hotel)
