Oskar von Reuenthal is a rear admiral serving in Reinhard's fleet and, along with Wolfgang Mittermeyer, Reinhard's ablest field commander. Born with a rare condition called heterochromia, one of his eyes is blue, while the other is brown. Since both his parents had blue eyes, this was seen as proof of his mother's adultery. His mother committed suicide after trying to pluck out his brown eye while he was still an infant.
