Having first come to the attention of American wrestling fans in WCW's cruiserweight division, Rey Mysterio has become known as one of the most popular high-flyers of all time. But with popularity, often comes unwarranted hatred. There's no denying that Rey was a smash hit in WCW, but was severely held down among the likes of Chris Jericho and the late Eddie Guererro because of upper management, who believed they were "vanilla midgets" and nothing more. To be fair, Rey did get the opportunity to wrestle Ric Flair for the WCW World Heavyweight Championship on an episode of Nitro in 1999. Mysterio debuted in WWE on July 25th, 2002. He has been employed by the company ever since, and has become more popular than ever. He connects with the younger audience members on an intangible level. He's quite literally a superhero to them. His mask and high-flying moves have made him a top merchandise seller in the WWE. He's put on thrilling matches against the likes of Kurt Angle, CM Punk and Dolph Ziggler, and is a former World Heavyweight Champion, as well as former 2-time Intercontinental Champion. But there are some fans who hate the master of the 619. Why? Well, I honestly don't know. While it's true that Rey is not quite the same as he was in WCW, or even during his first 4-5 years in WWE, he's still one of the guys who can put on consistently good matches with just about anyone. And when he's in a big match environment on a PPV, you are always guaranteed a fun time. But like another gentleman on this list, he's often ridiculed by the older, alpha male fans who don't want to be seen cheering "some kid's favorite wrestler". There's a weird thing in wrestling, where if children start to cheer for someone they like, there's an instant turnaround against that wrestler. It's odd, and I'm a bit bemused by these fair weather fans. Rey is loved by children. Granted, at a WWE show, you are allowed to cheer and boo whomever you want, and I won't tell anyone what to do, but all children need a hero to look up to, don't you think?
