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.

Off-Season 3
Somehow appeared in a match against Dan Schneider, how he's appeared here, is currently unknown.

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 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 5
On his match with Kirei, he seemed strangely subservient despite beating him, and Kirei didn't give his all. It also on Kirei's cash in that Johnny first appeared. Could Johnny actually be... Kirei's Servant?

Episode 6
Hideo Kojima revealed that he was actually the one who summoned Johnny to this world.

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.
