Kinnikuman: Kinnikusei Oui Soudatsu-hen

Kinnikuman has finally earned the right to inherit the throne of Planet Kinniku, but his coronation is interrupted by five new claimants. Each looks like a possible Kinnikuman and each insists that he, not the familiar clumsy hero, is the true prince who was separated from the royal family as an infant.

To settle the succession, the royal court establishes a Survivor Match in which the six candidates lead teams through brutal elimination battles. Supported by the Justice Chojin who believe in him, Kinnikuman must fight rivals backed by mysterious gods and master the Muscle Spark, the ultimate technique of his bloodline. The throne will belong not simply to the strongest claimant, but to the one who can prove what being Planet Kinniku's king truly requires.
