#4 Rey Mysterio - 5ft 6in (168cm)
The ultimate underdog, Rey Mysterio is undoubtedly the greatest Superstar in WWE history for somebody his size.
He won the Cruiserweight Championship on five occasions during his time with WCW, as well as four Tag Team titles, while he has also won the World Heavyweight Championship (x2), WWE Championship, Cruiserweight Championship (x3), Intercontinental Championship (x2), Tag Team Championship (x4) and United States Championship in WWE, making him a Grand Slam Champion.
When you consider that he also won the 2006 Royal Rumble, there are no doubts that Mysterio will end up in the WWE Hall of Fame one day.
#3 Lio Rush - 5ft 6in (168cm)
Lio Rush captured the attention of the wider WWE audience during his time as Bobby Lashley’s mouthpiece on RAW between September 2018 and April 2019, but his wrestling legacy will likely be defined by his incredible in-ring skills.
“The Man of the Hour” recently made his return to WWE television after a six-month absence by winning the Cruiserweight Championship from Drew Gulak on an episode of NXT.
At the age of just 24, expect to see a lot more from Rush on your screens over the next few years.
