Nub

Nub was one of the clone troopers stationed on the Rishi Moon Base, he appears in Episode 5 of Season 1, Rookies. It was another boring day on the base with Echo, Fives, Droidbait, Hevy, Cutup, O-Niner, and 327. But then the group lost contact with 327, who was the deck officer at the time. Sergeant O-Niner sent Nub and Droidbait to find 327. As Droidbait and Nub ran down the stairs, the doors opened and several Commando Droids ran out to meet them. Nub yelled "Droids!" before he and his comrade Droidbait were shot, his yell alerted the other clones who got their guns and began firing on the droids.
