Prawn NPC profile

[Gregorius]

I am thinking about incorporating the Prawns (from District 9) into an upcoming campaign. I think that the transformation process could really cause an interesting storyline, and, as far as I know, I can incorporate them without going very far out of the Canon for Star Wars or district 9 (we have no idea where they came from, so it is possible that they could be from the Star Wars galaxy, or at least be found there).

does anyone have a profile for an NPC Prawn?
I also need help finding a new name for them (I don't think that people in the star wars galaxy would come up with the same name).

some context may help. My idea is that my PCs are on a world enslaved by the Empire that has a population of Prawns (enslaved by the empire in Holocaust-style fashion of course [though if anyone thinks that I shuold change that please comment]) when a PC, or important NPC (maybe a high-ranking imperial) becomes infected and begons to mutate into a Prawn. From here, the actions of the character (or NPC) would determine what happens (maybe redemption, maybe fighting it all the way, maybe attempted suicide, who knows? Please tell me any of your ideas on this). This is also supposed to be fairlyt dark and gritty. (think of part- District 9, part star wars, with a small mix of Wallander-esque brutality and gore)
