Depends on what you're looking for. If you want a fight against a more lightsider (or at least more moral):
Tasha Blackmoor: I haven't set up NPC's for her ship, so you'd either have to just lemme say generalized skill with the weapons her company makes, or we'd have to wait. Or she just isn't in her ship at the time. Long story but she used to be a Jedi in her backstory, semi-hates them now, hates slavers much more. She'd probably be on bad terms with most sith, especially murderous ones. Somewhat strict sense of rules. Almost a militaristic force sensitive. She considers her use of the force more modern and has a lot more weapons and armor then a traditional force sensitive.
Rocho: Trandoshan Imperial Knight of the Fel Empire. I know it's kind of small at the moment so unless you're in Fel Space, it probably won't be a faction based thing. When not busied with Fel matters he often spends time bounty hunting, or just hunting in general. He's not a ruthless hunter like Cad Bane or Jango Fett. He has some kind of moral structure, and killing innocents isn't on it, so if you do that he'd totally fight you. (force sensitive but has a focus on the basics not the complex stuff). Or you know if you had a bounty on your head, he might go for that.
Salis would fight her too but more for fun. If it became a clear win or loss for her she'd just give up probably. She's one of my more powerful characters and has at least gotten finished fights with other master dark siders. I also realized I accidentally gave her a mix of combat styles like Darth Traya (but with prik daggers) combined with the use of turning her lightsabers on and off. She's a very combat centric joyful murderer. If you don't want to fight her though, she'd totally just hang out. She's an amoral weirdo with a love for fighting and mischievousness.
FOR NON COMBAT:
Did mention Salis already. She does love to fight, but she'll talk or play some game if there's something to keep her interested.
Nexus might find some way to talk with her but that'd require some thinking. He's not the type to just randomly wander streets (unless you're on Vran'ti, in which case he totally will, but possibly on a dragon). He kind of considers himself above most others. So if you do rp with him, know that I do rp him as a proud and arrogant piece of crap who was fortunate enough to be very powerful in the force and know how to turn his cowardice into a strength. (From an OOC perspective he's despicable but he makes a good villain)
I have Mag: He's the male Zeltron dancer slave I made that looks like Arnold Shwarznegger. (Weird but amusing day). Haven't done that much with him since his first thread. Buy him, free him, kill somebody where he works, talk to him, force throw him out a window, whatever works for you.
I can go more in depth on personalities, stories, or whatever if you want. I just wanted to get out a quick response for this.
