Muhammad Hassan was one of the most over heels in the history of wrestling and, had his gimmick been handled correctly and been given to someone with some decent in-ring skills, he could have been very big. As it turned out, Hassan - real name Mark Copani - really couldn't wrestle and his gimmick was done quite tastelessly at times and he didn't last very long at all in the WWE. He arrived in 2004, telling the world that he wanted to end the stigma attached to Arab-Americans after 9/11... then went on to be a part of such moments as calling for a group of masked men to choke the Undertaker out with piano wire. In his time in the WWE, he defeated wrestlers like Chris Benoit, Big Show, Batista and Chris Jericho, and he also competed for titles like Shelton Benjamin's Intercontinental Championship and John Cena's WWE Championship. Along with his manager Daivari, he also feuded with legends Shawn Michaels and Hulk Hogan, culminating in a tag team match at 2005's Backlash pay-per-view. He was released from his WWE contract in September of 2005 and then retired from professional wrestling completely. For someone with so little talent, he certainly competed with the best.
