Johnny Knoxville

The Jackass
A professional stuntman and leader of the Jackass group. He does the most impossible (stupid) stunts for the sake of it.

Season 3
Wrestles in the past during the HCTP! era (c. 2003).

Episode 2

The time merge allowed him to dare 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.

Episode 6
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.

Somehow appeared in a match against Dan Schneider.

Apparently, the time merge brought him forwards in time, or restored his youth.

Episode 2

Somehow appeared during a match against bane, but the weirdness didn't stop at that. Wrestlers seemed reluctant to want to fight and tried their hardest to not pin each other, making the match drag on 45 minutes. The Undertaker also showed up to attack Bane for some reason. The crowd chanted "Fight Forever!", and at several points the stopped wrestling just to look at each other for seconds before continuing. OP had Delta Mindhack them to fight, but a greater force kept pushing them to not wanting to fight. Hmmm...

Episode 4

Fights and defeats both a colony-dropping madman and a debt berserker, neither could push him close to his limits.

Episode 5

On his match with Kirei, he seemed strangely weak despite beating him, perhaps Kirei's evil was too much for him? Either way, he won the /v/ Title and rised to TFR champion.

Feats

 * 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.
 * Also beat Doomguy at an non-canon TLC match.
 * 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.
 * He also did so well against Jason thanks to the power of painkillers.
