Frehd'Enreek Mooncatcher was originally known as Catcher when he was an ARC during the Clone Wars. At the end of the war he left the new regime through secret means. He came across other ex-troopers by accident that had found employment as mercenaries and it was at their suggestion that he build a career as a bounty hunter. Like them, he wore a helmet that was internally like his old helmet but with a very different exterior. Throughout the Rebellion he took on every job but Jedi and Clone hunting. The former out of respect for the Jedi he served under and the latter, for more obvious reasons. Not often but there were two incidents where he helped Jedi and clone troopers. An aged Jedi master was running from another bounty hunter when he was coming out of the rear entrance of a restaurant. With no witnesses, he shot the other bounty hunter in the leg and knocked him out. He looked at the Jedi for a moment bowed and went around to the front of the building. The clone troopers he came across were part of a job which he later gave up when he found out that they were ex-troopers. He did find them but he gave them the name of someone that could help them settle somewhere more safe. The name he gave was Skirata.
Oh, and some people just called him "Fred" after he changed his name.
