Antimony Yoroibu

An element that has accompanied humanity through the ages — as cosmetics in ancient Egypt, printing type in medieval times, and flame retardants today. As an additive that hardens lead, it extends the life of lead-acid batteries, while antimony trioxide serves as a flame retardant protecting people from fires. A brittle, silvery-white metalloid with a somewhat old-fashioned and stubborn personality. An early-50s man wearing silvery-white armor with angular features. A supervisor type who values efficiency and durability.
