#1 Rey Mysterio - 5'6"
A pro wrestling great, Rey Mysterio showed that size didn't matter to propel to the top of the pro wrestling and WWE business.
The 5'6" wrestler wrestle in ECW and WCW, before making the switch to WWE. In WWE, diminutive Superstar won world titles, tag titles and even won the Royal Rumble, and has been a fan favourite throughout his WWE career.
His high-flying, acrobatic moves, and never-say-die attitude won him numerous fans around the world, and paved the way for smaller wrestlers to make it in the big-sized world of pro wrestling.
Mysterio, who left the WWE in 2015 after 13 years with the Vince McMahon-run promotion, wrestled in the indie circuit around the world. He returned to the WWE in 2018, and after months of speculation, signed a full-time contract to join WWE and SmackDown Live.
