Nuka Usikt was the Senator of Umbara, serving for five years until the beginning of the Alsakan Crisis. During the First Battle of Coruscant, Nuka initially opposed evacuation of the planet. Alcor Bac's support for evacuation, however, caused her to give in to the majority, and she followed most other senators in evacuating the planet. However, her vessel's engines detonated from Alsakan fire while Nuka was making her way to the last remaining hyperspace route, instantly killing her and the crew. Nuka was the only senator known to have been killed in the battle.
