Gregor

"You will be remembered, Captain Gregor. We'll take your heroic story back to the Republic, and we will watch for your return."

- Colonel Gascon

CC-5576-39, who came to be known by the name "Gregor," served as a clone commando and clone trooper captain with the Grand Army of the Republic, fighting the Clone Wars.

Gregor was in command of an elite squad, but was reported missing in action during the Battle of Sarrish. He ended upon Abafar with amnesia and was given a job as a dishwasher at the Power Sliders diner by Borkus for nothing more than room and board. After Corporal Meebur Gascon and his team of droids ended up on Abafar, they helped him to recover his memory and he in turn helped them to escape, but was left alone on the planet surrounded by hostile forces and facing near-certain death.

Behind the scenes
Gregor was only seen in "Missing in Action," an episode of the fifth season of the Star Wars: The Clone Wars television series. A preview clip featuring Gregor appears in was shown at Celebration VI. He is voiced by Dee Bradley Baker. A trailer for the show's fifth season includes Aurebesh on Gregor's profile notes indicating that he went missing in action during the Battle of Sarrish.

The markings on Gregor's helmet were inspired by the hash-marks that Boston Bruins goaltender Gerry Cheevers stenciled on his mask to denote the stitches he would have gotten had he not been wearing protective gear.
