Winry Rockbell

From Animepedia

Winry Rockbell is the Elric brothers' childhood best friend. When Ed and Al were young, they used to have fights over who would marry her. She lives in Risembool with her grandmother, Pinako Rockbell. Winry's parents, doctors, were killed in the Ishbalan war, when Winry was very young. Because of this, Winry values her friends very much, and hates to see them in the least bit of danger, lest she never sees them again. Winry and her grandmother are both automail mechanics, who Ed automail for his arm and leg. She will sometimes come with Ed and Al on their travels. She has fixed Ed's automail countless times, and if Ed breaks it too badly, or does anything else to put himself in danger, she will usually throw wrenches at his head. Winry is obsessed with mechanics in every way, shape, and form. She will often go wild at the sight or thought of mechanics or automail, making her a bit difficult to be around, especially in places like Rush Valley(the automail capital of the world). Even if Winry may be a bit insane at times, she is a very loyal friend to Ed and Al, who often wish that she did not have to see the pain that they are going through.
