Andorian

Andorians are a fictional race of humanoid extraterrestrials in the American science fiction franchise Star Trek. They were created by writer D. C. Fontana. Within the Star Trek narrative, they are native to the blue icy Class M moon, Andoria (sometimes referred to as Andor). Distinctive traits of Andorians include their blue/green skin, a pair of cranial antennae, and white hair.

Andorians first appeared in the 1967 Star Trek: The Original Series episode "Journey to Babel", and have been seen or mentioned in episodes of subsequent series in the Star Trek franchise. They were indicated to be a vital, important member of the United Federation of Planets in the 1997 Star Trek: Deep Space Nine episode "In the Cards", but did not gain considerable exposure until the 2001–2005 series Star Trek: Enterprise, on which they were used as recurring characters, most notably in the person of Thy'lek Shran, a starship commander who maintained a sometimes adversarial and begrudging friendship with Enterprise Captain Jonathan Archer. The series revealed more about Andorian ships, the home world Andoria, and the culture and history of Andorians and their subspecies, the Aenar. The 2004 episode "Zero Hour" established that Andorians were one of the four founding members of the United Federation of Planets.
