#2 Former WWE Champion Jeff Hardy
Jeff Hardy originally debuted in WWE when he was just 16 years old back in 1996. At the time, Hardy lied to the company about his age since there was a belief that he was 18.
Hardy and his brother Matt later made quite the impact in WWE as a tag team, before later going their separate ways. Matt and Jeff returned to WWE at WrestleMania 33 a few years ago, but Matt has since left WWE to compete for AEW whilst his brother Jeff has remained part of the company.
Hardy has wrestled under several names during his almost three-decade-long career but is best known under his real name.
#1 Former NXT Champion Superstar Keith Lee
Keith Lee made his wrestling debut back in 2005 and before he was signed by WWE he had already made a name for himself in Ring of Honor, Evolve and Pro Wrestling Guerrilla.
Lee was signed by WWE back in 2018 after being unsuccessful in a tryout 10 years prior. Interestingly, Lee was able to retain his real name and has been able to keep his real name throughout his career.
