actually Captian Nazi is a real character in the DC universe he was one of Captain Marvels first enemies and that general what ever his name is in the comics actually looks like that.
He's not a hulk ripoff when ever you give a guy a oversized body and small head thats really strong people think he's just like the hulk. Doomsday, shaggy man, solomon grundy not Hulk rip offs they just happen to share a common body type.
Also it was a great episode using members of the Seven Soldiers of Victory the precrisis versions any way. Shining Knight Rocks!
I was going to chime in with that, Dr. Fate, Captain Nazi is a Captain Marvel foe, he's actually more or less the arch-enemy of Captain Marvel Jr., he's the one that crippled Freddy in the first place. He's dead now, had his eyes gouged out in Villains United, given bionic eyes, then killed in one of the Batman titles.
