Billy Kidman is probably the best Cruiserweight in the history of the business. He flew his way through WCW winning numerous titles and huge fan power. Kidman was the Rob Van Dam of WCW and was one of the most popular wrestlers to step through WCW. Billy moved to WWE in June of 2001 as part of the WWE invasion angle. Since Billy moved to the WWE he has lost the fan power that he had in WCW and has definitely became less popular. But none the less he has still ruled the WWE Cruiserweight division.
