And he is still a huge box office attraction for WWE, enjoying three Universal Title reigns over recent years.
Lesnar will headline the huge SmackDown premiere on Fox next week as he looks to add another accolade to his collection when he challenges Kofi Kingston for the WWE Title.
His reputation commands big bucks, and he was reportedly the top earner in WWE with £9m in 2018, netting £375k per match and £75k from merchandise sales.
The former NCAA Division 1 wrestling champion always appeared destined for greatness after bursting onto the scene back in Vince McMahon’s company in 2002.
Within two years he was arguably the biggest star on the roster – but the lord of “Suplex City” had greater goals than wrestling greatness on his to do list.
In 2004 he decided to try and pursue his dream of becoming an NFL star and would have a short stint with the Minnesota Vikings that was curtailed due to injuries sustained in a motorbike accident.
But WWE owner McMahon was loathe to lose his star attraction and offered him a fortune to stay – only to see his huge contract rejected.
According to ESPN, Lesnar turned down a seven-year £36.5m deal when he walked away – worth around £5.2m-per annum.
That is mega-money – especially 15 years ago – for any one.
But fair play to Brock for following his ambitions… and despite his American Football dream falling to take-off he still has achieved greatness elsewhere.
In 2008 he defeated Randy Couture to win the UFC Heavyweight Championship and successfully defended it twice until Cain Velasquez took it from him in 2010.
And despite his reduced schedule nowadays in WWE, Lesnar is still one of the main men on the McMahon’s hugely-talented roster.
