In the mirror universe, Erwin Vierzinger was a sergeant in the ISS Arcadia's security division and the requested personal bodyguard to Lynnyn following the attempt by then-Security Chief Hafez to allocate a handsome security guard in order to compromise the Orion's position. Known as something of a 'snake', he was described as a slender man who was actually slightly shorter than Lynnyn herself and had "a pretty face which some men carried from their twenties to their fifties" with little facial hair.
