13) Nikolai Volkoff
The 1980s produced a multitude of "foreign heels," men who portrayed evil characters from other nations that... well, they weren't America, so that's about as far as the thought process went.
Nikolai Volkoff was one of those heels. He had a fantastic feud with Bruno Sammartino in the late 1970s and returned to WWE in 1984, when he had perhaps his best heel run.
He teamed with fellow foreign heel The Iron Sheik to form the Foreign Legion under the leadership of "Classy" Freddie Blassie. As the Cold War raged on, Volkoff garnered tremendous heat by singing the Soviet Union's national anthem before each match. Sheik would then often grab the microphone and say "Iran number one, Russia number one, USA (over-the-top spitting)."
Volkoff and Sheik took the Tag Team Championships from The U.S. Express at the first WrestleMania, and Volkoff later unsuccessfully challenged Hulk Hogan for the WWE Championship.
