#1 Brock Lesnar
Among the currently active WWE Superstars, Brock Lesnar is perhaps the only one to feature in the Guinness World Records. Lesnar holds the record for being the ‘Youngest person to win the World Wrestling Entertainment Championship’.
At SummerSlam on 25 August 2002, ‘The Conqueror’ defeated the then WWE Undisputed Champion The Rock to claim the title. Brock Lesnar was aged just 25 years and 44 days when he achieved this incredible feat.
Overall, Lesnar has been a four-time champion in the WWE, his latest title reign coming as the World Heavyweight Champion in 2014/15.
