#2 Raven (from Johnny Polo to an ECW legend)
After managing Adam Bomb and the Quebecers and occasionally wrestling with "Johhny Polo" moniker, Scott Levy(real name) left WWF in 1994. He headed up to the Paul Heyman's ECW and this is when his career took off to great heights.
Debuting his new character "Raven", a character inspired by Edgar Allen Poe's poem named Raven and Patrick Swayze's character in the movie Point Break, he feuded with Tommy Dreamer, another hardcore legend and together, these two set this industry on fire. Raven went on to become ECW World Heavyweight Champion by defeating The Sandman and was involved in a number of feuds with the likes of Shane Douglas, Chris Jericho and Terry Gordy to name a few.
He continued his success with the Raven character to WWE, TNA and independent circuit.
