Loser King vanished during the Planet Redevelopment Race a century ago, yet endures as an undefeated racing legend. His physical absence contrasts with his immortal legacy: track records still define competition standards across wheeled cities, where racers relentlessly chase his times as the ultimate benchmark of speed and skill.

His unexplained disappearance during the very race protagonists later attempt cemented his mythical status. A holographic projection—the Ghost Rider—now competes in every subsequent race, leading with unmatchable pace. Competitors invariably see only his retreating back, embodying his insurmountable legacy and the perpetual challenge he represents.

He epitomizes racing excellence, driving others to transcend limits despite the sport’s dangers. His light brown hair occasionally appears purple in certain accounts. The name "Loser King" wields ironic weight, nodding to his vanishing act while starkly opposing his undefeated career and enduring dominance as a spectral rival.
