MG-34, Nazi machine gun. Even their fricking guns look absurdly evil. With all the over-the-top villain tropes they were slinging around, it's a wonder they didn't realize they were the baddies. Totally giving someone a gun based on this. Probably a villain, but possibly a morally gray character. Helps that I'm adding a healthy dose of WWII dieselpunk aesthetics (among other things. It's a big universe) to my scifi series anyway.
