10 of the most bitter people in pro wrestling.

#6 Konnan

In the late 1980s and early 1990s, Konnan was akin to a Mexican Hulk Hogan. Not only was he a megastar, but he wielded political power backstage like the Hulkster.

Then he joined WCW and worked out a deal where he would bring other lucha stars with him. This led to the massive influx of Luchadores on WCW during the Monday Night Wars. He captured titles in WCW, but never the big belt...which might be why he became so bitter in later years.

Konnan spends a lot of time on social media bashing current stars, particularly if they work for WWE. He also engaged in a (losing) war of words on Twitter with Bobby the Brain Heenan before his passing. When he's being interviewed, Konnan has a hard time saying anything good about anyone but himself and the few people he considers worthy, such as Rey Misterio. Someone should tell Konnan that bitter people never prosper!
