Martian

A Martian was an inhabitant of the planet Mars. Martian was largely an equivalent term to Earthling as once employed by the Eleventh Doctor (TV: The Hungry Earth) — a term that applied to more than one species on the planet Mars.

Native Martians
Several native Martian creatures, such as the Ice Warriors, evolved on Mars, (TV: The Ice Warriors) as did many other Martian lifeforms, such as Martian fungi. (TV: The Seeds of Death) There were two sentient indigenous species on Mars. (PROSE: The Face-Eater) There was also a native virus present on Mars. (TV: The Waters of Mars)

Human Martians
By the 22nd century, Mars had been colonised by humans, who, according to one account, pushed the native Ice Warriors into poverty. (PROSE: Fear Itself) Another account claimed that humanity had colonised Mars unimpeded when — in the words of Harold — after "something to do with T-Mat on the Moon", "centuries" before the 23rd century, a whole fleet of Ice Warriors were — according to what Gregson Grenville had learnt in school — "all melted when their invasion fleet spiralled into the sun".

This account showed extant Ice Warriors, but all were in suspended animation for — according to the Eighth Doctor — "many millions of years" during the 22nd century. (AUDIO: Deimos)

Once humanity had made Earth itself uninhabitable, the Usurians saw to it that the humans could move to Mars. (TV: The Sun Makers)

Many humans considered themselves "Martian" after colonisation, as there came a point when humans were regularly being born there. Vel Karneen, commander of Space Army, identified himself as a Martian, for instance (PROSE: The Secret of the Mountain) —as did the second-in-command of the ADF, Reb Shavron. (PROSE: Terror Task Force)

Martian Droids
At some point, Martian Droids were paid in something called "default". (TV: Bad Wolf)

As colloquialism
Prior to colonisation, many humans simply interchanged the word Martian for the term alien — much like "flying saucer" was used as a generic term for alien spacecraft. For example, Donna Noble referred to the Tenth Doctor as a Martian before understanding he was, in fact, a Time Lord. (TV: The Runaway Bride) Likewise, Lucie Miller suggested to Eighth Doctor that she could be a Martian if she was alien. (AUDIO: Blood of the Daleks)

When the Eleventh Doctor said the Cuculus were alien, Harry Houdini asked if they were Martians. (PROSE: Houdini and The Space Cuckoos)

Misidentified Martians
Ostensibly because of this penchant to imagine Mars as a likely source of alien life, some humans occasionally misidentified other species for Martians, just as Donna had done with the Tenth Doctor.
 * Daniel Llewellyn thought that the Sycorax were from Mars until Major Richard Blake told him that Martians looked completely different. (TV: The Christmas Invasion)
 * Patrick also initially thought that the Centuripede came from Mars to read other people's mail. (TV: The Last Oak Tree)

Daleks Versus the Martians
The non-DWU story, Daleks Versus the Martians featured Dr. Who, Susan and Louise from the movies, Dr. Who and the Daleks and Daleks' Invasion Earth 2150 A.D., encountering a different species of native Martians to those encountered by the Doctor in the Doctor Who universe.
