And with good reason! He rose in fame at a young age, pulling up insane freestyle tricks, yet started before street skateboarding was a thing, and was overnight rendered obsolete.
But he went on to reinvent himself and created so many tricks, some he's still the only one able to do, or do with anything close to that level of mastery.
He then suffered a medical issue where his hip joint fused... Wasn't supposed to skate ever again but came back from it, relearning everything with a different balance.
He's over 50 now, and skating with such style[0], pulling off one-handstand flips which is insane at any age.
I respect Tony Hawk, but Mullen is an alien alright, less popular but so much more fundamental for skateboarding.
