Fan Casting Dr. Otto Giftmacher in Castle Wolfenstein

The Dark Prince of Pain. A white-haired, gaunt, clinically detached mad scientist in his 70s who sees human beings as experimental data. He created the Rat King, the zombie soldiers, and the cranial control devices. He scrapes neurotoxin from medieval paintings and dreams of watching Londoners eat themselves alive. He is not a sadist—he is a scientist who abandoned ethics decades ago.
