Kariage Evils, grandson of business magnate Kariage Maneko and heir to the Kariage Concern conglomerate, operates within a wealthy industrial dynasty fixated on power and influence. His grandmother’s obsession with attaining eternal youth via the fabled Paratopia drives their machinations, with Evils actively advancing schemes targeting Jun Yagami—pursuing her for marriage to fulfill Maneko’s ambitions.

A sudden amnesia-inducing tidal wave strands Evils and Jun in isolation, temporarily disrupting their adversarial dynamic and subtly exposing fissures in his resolve. Though the family’s later financial collapse triggers the auctioning of their assets, Evils’ personal adaptation to their diminished status remains undefined.

As a steadfast antagonist, he enacts familial agendas through calculated obstruction, collaborating with figures like Starzan S and the Robot tribe to thwart Jun’s goals, though his internal motivations stay static. His mother, Kariage Liz, and Maneko dominate his loyalties, steering collective strategies that range from manipulating the Robot tribe to constructing colossal robotic weapons like a Buddha statue.

Evils’ origins, education, and history prior to the 1984 series remain unexplored, his identity anchored to the Maneko clan’s comedic yet ruthless enterprises. No expanded media beyond the original television series delves further into his narrative.
