Johnny Knoxville

The Jackass
A professional stuntman and leader of the Jackass group, Johnny Knoxville had the idea to challenge the unbeatable Doomguy to a fight and see how long he could last, and that's what he's come to TFR to do.

Season 3
Johnny Knoxville is a wrestler in TFR during the HCTP! era (c. 2003) merge who dared take on Doomguy in a 3 match gauntlet when nobody else was willing to and despite impossible odds managed to win the first of those matches even if Doomguy completely wiped the floor with him and broke every single fucking bone in his body in the later 2 matches.

At some point, in another timeline, he fought HUNK, possibly to get more footage for Jackass. Somehow, he proved that painkillers are clearly stronger than nanomachines or Demon King powers, because he gave HUNK a fucking hard time despite eventually losing.

Feats

 * Beat Doomguy at an TLC match
 * Somehow lived after being reduced to a bloody pile of flesh by Doomguy and nearly beat HUNK
 * It took 12 Extraction Kicks and multiple Neckbreakers to put down Johnny, more than anyone else has ever taken
 * Even made HUNK bleed, possibly the first wrestler to do so
 * Beat THE FUCK outta Jason Voorhees and then BTFO'd him in a cutscene too

Trivia

 * It is believed that he did so well against Doomguy because all his stunts have left him unable to feel pain at all.
