Rey Mysterio is a former world champion. He is an immediately recognizable international superstar. He is marketed and merchandised as much as any other WWE superstar and his mask is an iconic symbol.
He is, perhaps, the most consistent sports-entertainer in the business. Yet, as great a performer as Rey Mysterio has proven to be, with a career worthy of a Hall of Famer, fans are often quick to dismiss him when discussing current great superstars.
The fact of the matter is that Rey Mysterio has proven himself capable of adapting his style to fit that of any opponent the company could choose for him. At Over the Limit, Mysterio did battle with R-Truth in a very solid match.
Then, one month later, at Capitol Punishment, Rey engaged CM Punk in what very well may have been the best match of the night. Truth and Punk are about as different as they come when comparing their in-ring styles. Yet Rey was able to utilize his skills to make a unique, different, quality match with each man.
Rey could be deemed "bulletproof" in that he has become such a major star that he can afford to lose to younger talent and not look any worse for it. His matches with the likes of Dolph Ziggler, Alberto Del Rio and John Morrison are among those individuals' best matches. They helped them to evolve and become better in-ring performers. Rey's selflessness is a trait other stars of his stature have proven incapable or unwilling to exhibit, making Mysterio a rarity in the business.
Outside the ring, Mysterio has proven to be one of the few major stars fans will pay to see. A match featuring Rey Mysterio means something and, outside of John Cena, Randy Orton, The Undertaker, and Triple H, that is something missing in the sport.
There are few true professionals left in the sport like Rey Mysterio. He is superstar who grew up in the business, who excelled at a young age, and who overcame a height disparity. He quickly became one of the all-time greats and deserves to be mentioned in the same breath as Cena, Triple H, The Undertaker, The Rock, Steve Austin, Bret Hart and Shawn Michaels.
