He's only 5'6" and weighs 175 pounds, but it hasn't stopped the incomparable Rey Mysterio from fulfilling enormous aspirations like earning the WWE Championship or outlasting 30 superstars to win the Royal Rumble as the No. 2 entry. When Rey Mysterio departed WWE, he left a huge gap that the organization is still attempting to fill. There's a case to be made that when Rey Mysterio was at the peak of his career with World Wrestling Entertainment, certain members of the WWE Universe didn't completely appreciate the brilliance that we had in front of us. Mysterio also won the Tag Team Championship four times, making him the WWE's 21st Triple Crown and Grand Slam champion. He also competed in the Royal Rumble and has headlined multiple WWE pay-per-view events. After leaving WWE in 2015, he wrestled in New Japan Pro-Wrestling (NJPW) and AAA before returning to WWE in 2018.
