Even though, most hate to admit that WWE is the biggest and famous wrestling event in the world, and also the ultimate destination if you're a professional wrestler! Some wrestlers work on smaller promotions with a definite group of hardcore fans, while there are others who wish to see themselves on a worldwide platform, and be accessible to millions of fans through social media. Some superstars of WWE seemed to have left the WWE fame at one point, but rumours appear that they could make a possible return to WWE sometime in 2016. Check out, who might come back on to the WWE hall of fame! Rey Mysterio Rey Mysterio, since his wrestling career that began in 1989, has competed in several promotions worldwide.

Officially, his contract ended in February 2015, after 13 long years. Since then, he has been focusing AAA in Mexico and independent circuit, also appeared in Lucha Underground.

MR. Kennedy

Ken Anderson, also known as Mr. Kennedy or Mr Aderson is another wrestler who has been underused in TNA wrestling since he joined in 2010. He has been a crowd favourite always, but managed to win only a United States Championship and the money in Bank contract in 2007. He has been the vice-president of Aces & Eights. Anderson is not doing much in TNA anymore, so his career would likely be revived with a move back to the WWE.
