Movie
Description
Octopus Dragon III is an antagonistic devil chojin who appears as the main antagonist of the first Kinnikuman theatrical film, Kinnikuman: Stolen Championship Belt, released in 1984. He is a green-skinned devil chojin whose attire consists of armbands, wrestling trunks, black boots, and a dark cape. He serves as the leader of the Space Underground Pro Wrestling Federation, a brutal organization of fighters who are willing to use all kinds of methods to defeat their opponents. His homeland is Planet Metro, and his listed chojin strength is three million power. His favored attack is called the Cruel Attack, a name that reflects the harsh, no-holds-barred approach that defines both his fighting style and the organization he commands.

The character is presented as the apparent grandson of Octopus Dragon, an octopus-like kaiju who appears in the original Kinnikuman manga and television series. However, the film version of Octopus Dragon III is a distinct creation with an entirely different appearance and personality from that earlier monster. He is exclusive to the theatrical feature, with no corresponding appearance in the serialized manga story, and his connection to the earlier creature exists mainly through family lineage rather than through shared abilities or behavior.

In the film's storyline, Octopus Dragon III and his minions steal the championship belt belonging to Mari and Kinnikuman, an act that sets the movie's central conflict into motion. As the boss of the organization responsible for the theft, he functions as the primary adversary whom the heroes must overcome in order to recover the belt. The film brings Kinnikuman into direct confrontation with him, and the hero's allies among the Justice Chojin, including fighters such as Terryman and Robin Mask, become involved in the struggle to oppose him and his forces.

His motivations are those of a wrestling antagonist who rejects the ideals of fair competition: he seeks to assert the dominance of his underground federation through theft, intimidation, and brute force. The organization he leads is characterized by cruelty and rule-breaking, and his signature attack is meant to embody that ruthless philosophy in combat. Because he was created for a single theatrical feature rather than an ongoing serial, he does not undergo long-term character development; his role is confined to the film itself, where he acts as the leading obstacle whose defeat is necessary for the stolen championship belt to be returned to its rightful owners.
