Have him be a Herglic. Normally a very nice person, but happens to be working for some very unpleasant people. Say, a Hutt or someone similar.

Ah. You're right. I was thinking of a different villain.

An Herglic would be great as a Sallah type character from the Indiana Jones mythos. They're a little more jubilant than a Wookiee.

I was disappointed that Herglics didn't make it into Fly Casual.

I don't know what you're going to make him mechanically, but you should totally name him "Ohio Roberts".

After much consideration I've settled on the character,

Malè Arc-Turo, Twi'lek Archaeologist / Con Man. Going to do my best with a French accent and everything, he of course has his own tragic backstory and a personal Zabrak bodyguard named Zaado along with his near army of paid goons.

But wait, there's more. Also joining the rogues gallery is Nemoidian Crime Boss Mon Gutza, a criminal enterprises extraordinaire, having his fingers in all kinds of situations the PCs get into. And to top it all off is Inquisitor Natalia Forscythal, also known as the Second Sister. Known for her speed and precision, her hunts always end in humiliating her quarry before ending them. All three will give my group quite a bit of trouble.

Gungan... feel the BURN!!!!!
