Pinako Rockbell

Pinako Rockbell is Winry's grandmother. Pinako took care of Winry after her parents died. She is an extremely skilled mechanist and, along with Winry, she helped create Ed's automail arm and leg. She also is rather short, fighting with Edward about their height consistently. While she may seem strict, she has a genuine care for Ed, Al, and Winry and would do anything for them.

Trivia

 * In an omake strip, Hiromu Arakawa revealed that Pinako hides Nattō beans in her hair, although this is probably not to be taken seriously and might have been only intended as a joke.
