PANZER.

So back in the day I used to play this pen and paper superhero RPG with a group of friends down at the local hobby shop and we had this recurring villain named 'Panzer' who was a WWII Nazi cyborg who was reawakened in the present day and would frequently take on the entire team of us, often coming very close to bloody well killing us all. He was the coolest villain we fought in my opinion and we always dreaded having him show up in our games. I always had this image of him in my head as this horribly scared and mutilated aryan man encased in this huge, hulking juggernaught of a powered exoskeleton, a slightly tragic figure, but completely menacing and determined.
