Biography
Prior to the Skirmish at Vanqor, Jedi knight Anakin Skywalker allowed himself to be captured by a Munificent-class star frigate, commanded by Count Dooku in an ice field near Vanqor. Once inside the ship's hangar, he put up a fight in order to make his capture look convincing. He was defeated and taken to a prison cell.

Jedi Master Obi-Wan Kenobi later infiltrated the ship to release Anakin in order to help apprehend the Count. When he reached the brig, the Jedi opened one of the cells, only to find this Nikto and a fellow one inside. Kenobi then told them to stand down as they were not the prisoners he was looking for, and closed the door. The two Nikto were presumably killed later, when a Galactic Republic Star Destroyer opened fire on the warship and destroyed it.
