I did create a thread just like this about a year ago for Mass Effect 2, but I thought I would start a new one for peoples Mass Effect 3 characters. Please no spoilers about the game, I myself haven't finished it yet and I am sure there are others who haven't as well, so NO SPOILERS! 
Here's mine, he's called Tom Shepard. I've gone for a less renegade character this time, but as far as I can tell the morality system isn't as important in this game (correct me if I'm wrong). I think I may have slightly more paragon than I'm comfortable with but apart from that and the generally creepiness of his face I'm quite happy with my character.
