Grumman

Serving as the commander of the eastern headquarters, this high-ranking officer is the grandfather of Riza Hawkeye. Because he operates outside the direct oversight of the Homunculi, he plays a pivotal role in assisting Mustang’s mission to overthrow the corrupt, puppet government. However, his motivations appear far from heroic, as he seems driven primarily by his own underlying personal ambitions rather than a selfless desire for justice.
