Big E and Finn Balor may have something to say about that, but the fact that the former champion received a standing ovation at SummerSlam 2021 tells you everything you need to know about his popularity.
Before he took the WWE by storm, Lesnar was an amateur wrestler and finished his unpaid career as a two-time NCJAA All-American.
His background in the collegiate system served him well as he remains the only person to win the heavyweight title in the UFC and WWE.
Not only did he defeat former champions along the way, but he finished them in style as well.
This earned Lesnar "the best in-ring performer of all time" title, according to his arch-rival, John Cena.
It doesn't get much better than that.
Over the course of his 21-year career, 'The Next Big Thing' has broken so many records and paved the way for future generations of WWE stars.
Just ask Gable Stevenson - he wouldn't be where he is today without the help of his friend and mentor.
There have been some truly unforgettable moments as well.
Who could forget his epic SummerSlam bout with The Undertaker in 2015 or his hilarious scrap with Paul Heyman? Lesnar's bully character may have rubbed some people up the wrong way at times, but there's no denying the wrestling business would be far worse off without him.
And now Lesnar will return to the ring this weekend for the first time since his loss to Drew McIntyre at Wrestlemania 36 when he takes on one of his toughest tests to date - current WWE Universal Champion, Roman Reigns.
Ahead of the match, we thought it would be a good idea to put together a quiz about Maryfield's finest, to separate the true Brock fans from the rest.
