I'm going to have to say Winry - because the way she cares for Ed and Al (while trying not to show it) and worrying/looking after them exactly what I do with my friends. (and yes - I throw books and wrenches at them when they do dangerous things too...)
I don't know. I don't resemble any of them very m,uch to be honest. If I had to pick one, I suppose it would be Sciezka because I'm quite quiet and in all probability gay for Hughes (come on, who isn't? He's like the Johnny Depp of anime). Also my hair is the same colour as her's and similarly messy.
Alphonse. Because HE likes animals...I like animals. It totally works. Oh and the personality too.
