Vosu Puk is a decent medic, great mechanic, and an overall neutral guy. Space wizards and the empire never really affected him living in Hutt space. But being a versatile individual is invaluable to a Hutt. Vosu was “drafted” as a bargaining chip when he was working for 1 hutt to pay a debt to another. That was a problem, he was enjoying his employment with his Hutt. He patched up the bounty hunters in the morning and repaired their droids and ship in the afternoon. But his new Hutt cared not for his versatility. Only using him as he saw fit, which was not a good fit. Now one might assume that Vosu would just leave. Jury rig a ship to be space worthy and blast off. Things are never so simple, Vosu’s little sister was also sold to the offensive Hutt, trapping him with family ties. Needless to say, Vosu is quite discontented with his current predicament.

Sure he's heard of the moisture farm kid (skysprinter or something like that) and his battle with the evil emperor (palpation or something like that) and his right hand robot Darth (raver or something, sounds like a fun guy). All that was so far beyond Vosu that he never ever bothered to learn what happened off-world unless it affected spaceship part prices or fuel prices.

10 Responsibility : Vosu is being blackmailed by his hutt boss with the life of his sister. He feels responsible and is allowed to see her (through the holonet) on occasion to reinforce his loyalty.
10 Debt Vosu owed a life debt to his previous hutt but that debt was sold to his current hutt.

Vosu is an average height and build Mirilan male, with darker green skin from his days in the sun fixing ships. he wars mechanics garb over some armored clothing when going out. If he's not, which is more than typical, much more than a tank top isn't necessary. He always carries a backpack filled with gear for his team, as if they aren't going home he probably isn't either.
