Martians are aliens native to planet Mars.
ALF describes a group of Martians as "a mean family of cucumbers," this implies that Martians are possible plant based lifeforms, or they look like plants.
Relationship With Other RacesEdit
The Martians seem to have a bad relationship with the Melmacians, as the Melmacians celebrate the National Rag on the Martians Day. The Martians are also hostile to Melmacians it's seems as well from what ALF states.
