TK-1104
Got some possibilities for you.
He could run into Rocho, Kat Kenrid, Kovhorn, or Vaya.
Rocho: Trandoshan bounty hunter/Trained force sensitive. He is out for points though he'll almost always only go after those who have already themselves attacked someone not out of self defense. However if you're walking around armed or have any kind of force or clear skill, he's more likely to act. Not super moral but not completely immoral. He has his own ship, two actually, and is fairly rich he just doesn't use any of it.
kat Kenrid: Force sensitive (recently discovered) Falleen bounty hunter/smuggler. She's a capable manipulator but also has taken up Mandalorian armor and some of their ways after a woman who freed her from slavery died so she chose to honor her. She's not as physically dangerous as Rocho but she's still pretty good. She would probably be easier to talk to as Rocho might be intimidating to some and doesn't have a ton to say unless you're in a fight with him.
Kovhorn: New character for me, a born Mandalorian whereas Kat simply took up the armor and ways from an indipendent. Kovhorn is a very skilled fighter and has heavy armor. He'd possibly go on Bounty Hunts or do short term Bodyguard jobs. He's a little less talkative then the other two unless he knows you.
Vaya: Only works if you go to Ryloth. She's a twi'lek animal trainer as a job. More friendly then Kovhorn, maybe closer to around Kat kenrid. She is not a complete push-over in combat but you won't find her proudly going into combat. There are a lot of times where Vaya relies on her skills with animals to save her, slight force sensitivity helps with that.
