Leon is a "Terror is Reality" contestant who idolized Chuck Greene when he was a professional motocross racer, but thinks he has gone soft since then. He is a survivor of the Las Vegas zombie outbreak, and a psychopath in the Fortune City outbreak.
Leon confronts Chuck in front of the arena, revealing to Chuck that, despite his hostility, he was a massive fan of Chuck during his motocross days, but now believes Chuck to have gone soft. He then murders a nearby survivor by cutting him down with his slicecycle, having decided that the outbreak is nothing more than an extension of the games where humans are worth "double points". Leon then goads Chuck into a motorcycle battle through the Platinum Strip after throwing him a bike key.
Upon his defeat, his motorcycle's gas tank springs a leak as he heads back to his motorcycle trailer. After he sees Chuck, Leon taunts him more and begins to spin his bike in a low dip, causing the attached chainsaw to create a spark and ignite the bike and himself. Leon continues to taunt Chuck as he is immolated, claiming he will never beat him. When Leon finally falls to the ground, Chuck dryly quips, "Yeah, you're on fire".
Killing Leon unlocks his motorcycle trailer, which contains a motorbike and a workbench for creating customized vehicles, like the slicecycle.
- Leon is the only psychopath from Dead Rising 2 not to return in Dead Rising 2: Off the Record, instead being replaced by Chuck, who has a similar attack pattern to Leon's.
