Winry Rockbell (Japanese: ウィンリィ・ロックベル, Hepburn: Winrī Rokkuberu) is a fictional character from Hiromu Arakawa's Fullmetal Alchemist manga series and its adaptations.

Winry is a teenage mechanic who often spends time with the central characters, brothers Edward and Alphonse Elric, who are childhood friends of hers.

Specializing in mechanical repair, specifically prostheses called automail, Winry services Ed's replacement arm and leg.

Originally meant to be introduced in the series' first chapters due to its lack of female characters, some of Winry's traits are based on Arakawa's own life.

In the first anime adaptation, Fullmetal Alchemist, Winry is voiced by Megumi Toyoguchi in Japanese and by Caitlin Glass in the English version.

[6] When asked in 2006 who her favorite Fullmetal Alchemist characters are, Arakawa found it hard to decide, but at the time she picked Winry along with the Elrics and Riza Hawkeye.

After Scar escapes, Winry is urged to return to Rush Valley by her loyal customers, and Ed promises her the next time he makes her cry they will be tears of joy.

[18] After the Elrics and Roy Mustang discover Bradley is a Homunculus, Winry and Riza Hawkeye respectively are used as hostages by the military to gain their obedience.

Winry later discovers that the Elrics have traveled North, and she heads there as well since Ed's automail is not suited for those conditions, in which he could die; State Alchemist Solf J. Kimblee escorts her there to emphasize her "imprisonment" and gains her trust.

[19] In order to both evade the military so she can no longer be used against the Elrics and secure freedom for her allies, she has a brilliant plan and decides to pretend to be Scar's hostage to cover her group's escape.

When she goes into her house, she tries to change clothes, only to find Ed in her room flusteredly staring, causing her to scream before calming down and having a conversation with him, saying she has missed him since their last time together.

[21] During the Promised Day, Winry is killed upon the activation of the Gate, her final word being "Ed", but is resurrected along with the rest of the country by Van Hohenheim.

[23] Winry continues traveling with the Elrics until she learns that her parents were killed in the Ishvalan massacre by Ed's superior Roy Mustang on military orders.

Winry goes to Central to meet Mustang, but is unable to talk to him when she hears from several people that he is highly respected by his friends, including the deceased Maes Hughes.

[24] Winry later meets and befriends the librarian Sheska who suspected the woman Juliet Douglas, who is in fact the homunculus Sloth, for being responsible for Hughes' death.

Released on June 22, 2009, the CD features tracks based on her character performed by her Japanese voice actress in the first Fullmetal Alchemist anime series, Megumi Toyoguchi.

[31] In popularity polls from the manga published in Square Enix's Monthly Shōnen Gangan Winry was commonly featured in the top ten, reaching fifth place in 2009.

Writing for Pop Culture Shock, Lydia Hojnacki listed Winry as a female characters she likes from the Fullmetal Alchemist while commenting on her relation with the Elric brothers.

[41] Holly Ellingwood, a writer for Active Anime, also praised the moment, describing it as an "emotional struggle" and noting that "her own actions afterwards are some of the most riveting of these latest chapters".

"[44] Anime News Network's Carlo Santos praised how her appearance in the north from Amestris while meeting the Elrics brothers was a "complete game-changer" due to her status as a hostage.
