While Rex and Cody may be two of the most popular clones from Star Wars: The Clone Wars, there is a lot of love for Gregor as well. No one expects Star Wars fans to remember every single clone who ever graced the screen in Clone Wars, so don’t worry if you don’t remember who Gregor (or CC-5576) was.
Gregor was in command of the Foxtrot Group, which was an elite commando squad, though not quite as elite as Clone Force 99. During the Battle of Sarrish, Gregor went missing and was believed to be dead, but he eventually woke up on the planet Abafar with no memory of who he was. He took up a job as a dishwasher at a diner, grew out a beard, and never realized who he truly was. When Republic Colonel Gascon crash-lands on the planet and discovers Gregor, he thinks the clone is working undercover.
Gregor is obviously confused and alarmed to discover that he is apparently a clone and his confusion is only worsened when he discovers a hologram of Rex. Gregor eventually makes his way home and resumes fighting for the Republic alongside his brothers. Gregor makes an appearance in The Bad Batch when Rex asks the Bad Batch to rescue Gregor from where he’s being held captive. He is quite jovial, despite his situation, which is presumed to be because of the head trauma he’s endured during his life.
During Rebels, Gregor is happily living with Rex and Woolfe on Seelos, where they are enjoying life in retirement.
