Sinker

Sinker was a clone trooper sergeant who fought in the Clone Wars. A member of the Wolfpack, he was under the command of the Jedi Master Plo Koon . He was stationed on the Triumphant when the ship and two other Venator-class Star Destroyers chased General Grievous' secret weapon to Abregado. The Malevolence destroyed all three ships, but Sinker, along with Jedi Plo Koon, Boost and Wolffe managed to escape via an escape pod. They were attacked in their escape pod by battle droids but were able to defeat them, thanks to Koon's skills. Koon was able to reach Padawan Ahsoka Tano, who was along with her master on a rescue mission for the battle survivors. Skywalker and Tano were able to rescue the pod and escape the Malevolence. Sinker would later serve under Koon in many missions.
