Martian

Martian was a generic term used in many universes for the sapient species native to Mars.

In one universe, the Martians were humanoids who were outwardly identical to “Earthians”; they actually had different biology, but it was possible for hybrid children to be born. (PROSE: Magician From Mars…)

In several universes including the 97th Cosmos, the Martians were instead octopus-like beings who used Tripods and subsisted on other creatures' blood. They were sometimes known as Wellsians. (PROSE: The Grand Multiverse Hotel, COMIC: Miss Adventure, etc.)
