Lethan

Lethan Twi'leks were Twi'leks who had the rarest of all skin colors: red. This was caused by a mutation in their genetic code. On Naos III, many female Lethan Twi'leks were hidden.

Shakka, Alora and Fa'ale Leh were Lethan Twi'leks. Senator Orn Free Taa also had one as his consort. B'ink Utrila was also a Lethan Twi'lek.

The Sith Lord Darth Talon of Darth Krayt's new Sith Order was a Lethan Twi'lek. Her master, Darth Ruyn, also appeared to be Lethan, although it should be noted that a number of Krayt's Sith followers sported red and black tattooing, perhaps in homage to Darth Maul.
