The Likash, described as Likashan when used as an adjective, hailed from the Likasha system and were affiliated with the New Republic. In the waning years of the Galactic Civil War, the Likash's representative in the Senate adopted a forceful position, contending that the New Republic's armed forces possessed sufficient strength to completely defeat the Imperial Remnant, even with the resurgence of Grand Admiral Thrawn. Previously, the Likash had lived under the rule of the Empire.
A notable characteristic of Likashans was their voices, which possessed a high pitch.
