Desann, best character from the Star Wars Universe yet. Well, thats my opinion anyways. Yeah, Assaj Ventress is cooler, but I just have a soft spot for Desann, he never gets enough loving. Check him out in action here: http://www.youtube.com/watch?v=vL1ljx4t1ps

And his apprentice Tavion, love that gal. They work so well together.
