Nachiguron

ナチグロン

Nachiguron is a weak Kaijuu who fears humans. Kinnikuman is sent to battle him, but upon realizing Nachiguron is harmless, he allows him to leave. Originally standing 60 m tall, he shrinks to approximately 1 m and moves in with Kinnikuman and Meat at Beverly Park. Meat initially objects to the arrangement, already burdened with caring for one large baby (Kinnikuman), but agrees on the condition that Nachiguron looks after himself. He gives Nachiguron a special whistle to use if he ever gets into trouble and sends him out to buy groceries. Nachiguron is then confronted by the Kaijuu Yakuza for siding with Kinnikuman. He almost blows the whistle, but instead decides to handle the situation himself. He appears from time to time to cheer on Kinnikuman or serve as a referee, but is not seen again after the Choujin Olympics. In the anime, however, he first appears during the Choujin Olympics as Zangyaku-seijin's cowardly minion, but eventually sides with Kinnikuman. He then assumes the role of Kinnikuman's second sidekick and is frequently seen with Meat throughout the rest of the anime.
Nachiguron is bald when he first appears, but in the next chapter he has shaggy blonde hair, which remains his hairstyle for the remainder of the series. In addition to his cowardice, he is also a very loud snorer. He is named after a kind of candy called Nachiguro (那智黒).
He did not appear in the Kinnikuman Nisei anime.
