My favorite PC (That means, the PC I like the most in the group I'm GMing!) is Private Maximillian Butter. Born in New York, he started as a ballet-dancer. As he had a kick for drugs, he came into a criminal career (selling drugs, theft). Things ran the way they had to, and "Butters" landed in jail. When the war broke out, he was drafted to the airborne infantry and at least landed in the 5th Inf. Div. (Mech).
Oh, he's black, tall, very agile - not so strong. He still has a kick for "Mary Jane" and - this was obvious, wasn't it - he is gay. His haircut is slightly going in the direction of 70ies "afro-look". He is the only former civilian in a bunch of professional soldiers. Well, because the player listened when the rules were explained, he is by far the best observer and is really good at Kung Fu. He is the only one able to lockpick und the player portrays him as really fairy/effeminate (Hm, in German we say "tuntig". I'm not quite convinced, that my dictionary gives me the right vocabulary in this case

).
We had a lot of fun with this character. He is a kind of sissy, everybody tells him, what to do, but he has his fun - oddly enough.
The other PCs have some serious difficulties with him (you know: dicipline and such ...) but I and the guy playing Butters, had lots of fun ...
BTW: The player is one of the toughest guys I know. And he is so not-gay in reality, that it is really very funny.
