He got his first major exposure as a wrestler in 1991 in World Championship Wrestling under the name "Scotty Flamingo," and won the short lived WCW Light Heavyweight Title in 1992. He left later that year.
In early 1993, Levy joined the then-World Wrestling Federation but was made into a manager and dubbed "Johnny Polo" and was placed with the Quebecers tag team. He led then to a few reigns as WWF World Tag Team Champions before leaving in 1994. He would then start to make his impact in professional wrestling.
In 1995, now bulked up to 230 lbs., Levy debuted in Extreme Championship Wrestling under the name "Raven." Levy enjoyed two reigns as ECW World Heavyweight Champion during his tenure in ECW. He started a legendary feud with Tommy Dreamer that lasted for the next two years, before Dreamer finally defeated him at the ECW Arena in Philadelphia, PA in June 1997.
Levy then left ECW and rejoined WCW soon after that. He would enjoy some moderate success in WCW, but never reaching main event status like he did in ECW. He left WCW in 1999 and rejoined ECW teaming with his old enemy, Tommy Dreamer.
A reluctant tag team, Raven and Dreamer reigned as ECW World Tag Team Champions for several months. When they lost those belts, they feuded once again before Levy left for the WWF in the summer of 2000.
Levy's WWF run was not a success. He could not reach above midcard status and was used mainly on the "B" shows before being released in early 2003. Levy's main exposed since then was for NWA:TNA.
A journeyman, Levy had made a mark in every major company in professional wrestling. He will probably be remembered for his days in ECW than for his other tenures in wrestling.
