Mine is Maes Hughes. He was a pretty cool cat. I loved everything about his personality. I actually cried when he died. (I blame being preggers. sweatdrop) Especially during the funeral when Elicia was tugging Gracia's dress... crying
**EDIT: Homunculus do count. Just saying because of the minor confusion.
Maes Hues was my favorite character. And don't worry, I was crying to. I even cursed Envy a little XD and the part that made me cry was the funeral.
Realistically speaking, there is no 'one' character I 'loved'. Like most series every individual played their own roll. Maybe Sciezka, if I 'had' to choose, her continually changing demeanor I found pathetically funny.
