I named my Shepard "Lion". This is because I am a furry with a lion fursona and lions are also generally regarded as being quite hard, thus fitting in with his character quite well. Sure he could have been an utter wimp as a kid but fuck it, it's my Shep and I'm sticking to it!
While I haven't got a screencap, I did alter his appearence quite a lot...I tried to make him look like me, seeing as Mass Effect is supposed to have a RPG element here and there. Sadly he looks better, has muscles that are bigger than knots in a wasp's penis and has a backbone made of something considerably stronger than crepe paper dipped in turpentine.
