Justin Credible rose to fame in Extreme Championship Wrestling, winning the Heavyweight Title from Tommy Dreamer. He stared off in the WWF with two failed gimmicks and headed for greener pastures at ECW. He became famous there, but the company folded in early 2001. Instead of wrestling in the independent federations, WWF offered him a contract.
Credible debuted in the World Wrestling Federation alongside X-Pac. The two then added Albert to their group to become X-Factor. Justin seemed to have faded away from WWE as the X-Factor dissolved. Who knows where you will see him next.
