NEW YORK ( TheStreet) -- A hero is nothing without a villain to vanquish, which is just as true in professional wrestling as it is in movies, television or books. WWE has no shortage of villains to choose from across its 60-year history, and there are hundreds of worthy candidates to make a list of "Greatest Villains/Heels."
But the best of the best deserve their own recognition for their work as villainous characters. As "Macho Man" Randy Savage once said, "the cream will rise to the top." So let's jump right in and take a look at the Top 15 Greatest Villains/Heels in WWE history.
15) "Superstar" Billy Graham
"Superstar" Billy Graham deserves a spot on this list simply for his historical significance as a heel. His 296-day reign as then-WWWF Champion from April 30, 1977 until Feb. 20, 1978 still stands as the longest uninterrupted reign for a villain. Graham's win over Bruno Sammartino and subsequent reign was previously unthinkable, as heels almost always immediately lost the title before it went to a babyface.
Graham was also one of the first so-called "cool heels" who stayed popular with fans despite his villainous status. He planted the seed for men such as "Stone Cold" Steve Austin and The Rock to become antiheroes that fans would love.
