Joliot Comanche, the Silver Alchemist, is exclusive
to the manga.
Comanche fought by transmuting objects into steel weapons.
He lost his left leg in the Ishbal war, but has replaced it
with a peg instead of automail. Despite this apparent
handicap, he was apparently quite agile, even performing
acrobatic spins on his peg-leg as he fought Scar. Like
Kimblee, he had transmutation circles tattooed on his hands,
though Comanche went a step further and had them etched all
over his hands, rather than just on the centers of his
palms. In issue #43 of the manga, he was assassinated by
Scar. Scar killed him by snapping his leg and knocking him
off a dock, dropping him into the harbor below. Deprived of
raw materials to make weapons with, he was easily finished
off.
