"I like my red lightsaber. I'll use that."
Sith Apprentice. I don't think I have what it takes to be a true Sith Lord, but I think I would serve the Dark Side better in my lesser capacity.
I love the Red saber, and I would go daisho-samurai-style with one long and one short, like I did in KOTOR.
I know they don't have this color, but somehow my short saber would shine blacklight (In KOTOR, I used long red and short purple). Alternately, my short saber could lengthen, so I could have two full lightsabers and even join with the red saber, making a two color double lightsaber. Or make both Red. Or Blacklight. Whatever color I deem at the touch of a button, sometimes in the middle of combat. I don't think they do that, but that's just me.
Finally, in terms of looks. I would also look a lot like my onnagata avatars, with long-quasi-japanese looking black and grey Sith robes. Now I'm going to make a new avatar...more to come...
