Роа

A chimera that follows Greed. He was fused with a bull, making him as strong as one, as demonstrated to Al when he literally knocks Greed's head off with his hammer (Greed, naturally, recovers from this). He wields a hammer as his weapon and has an ability to transform into an enhanced version of himself with more bull-like aspects like horns and greater strength. He's the only one of the three that fought in Ishval. He cameos in the 15th volume, shown as a background soldier, after Roy Mustang's appearance in the battle ground.
