Andromedan

Andromedan was a which meant "someone from the constellation of Andromeda". Since it included beings from different planets, such as Salostopus, it did not actually suggest a single species or culture. (DW: The Trial of a Time Lord, DWN: The Ultimate Foe)

Some Andromedans were known to have lived on Earth for a while, and later ransacked the Matrix on Gallifrey. This act was one of the proximate causes for the Sixth Doctor being put on trial. (DW: The Ultimate Foe) The criminals Sabalom Glitz and Dibber were also Andromedans. (DW: The Mysterious Planet)

Andromedans were used to travelling long distances in suspended animation. Such Andromedans were called "Sleepers". (DW: The Ultimate Foe)
