The Fury is based on a real-life person (very much not Jack, lol), and that's just how I draw him in my art. Since this sketch was set in WWII, and the first Soviet cosmonaut to orbit the Earth (a guy called Yuri, the name name as we've given The Sorrow) did so in 1961, The Fury didn't go into space or have his accident until after that. Even the first little Russian dog in space didn't go up until 1957.
Even though The Fury's mission may well have been an early one, since it went so wrong, the Second World War was too early, so I just cast him as a thermophile and medic, like myself in all the best video games. 8B
