Ataru is the older brother of Kinniku Suguru, the protagonist of the series, and the eldest son of the Royal Kinniku Family.

In his childhood he could not endure the strict Spartan-like training his parents put him through and ran away from home. Because this all happened before Suguru's birth, Suguru was never aware of Ataru's existence.

Ataru watched over his little brother from the shadows as he fought against Evil Choujin, making sure he learned the value of friendship, and then returned after 25 years during the Survivor Match for the Kinniku Throne.

As an experienced Senpai Choujin, he is viewed as an older brother to not only Suguru but the other Idol Choujin as well.

Ataru possesses what he refers to as True Friendship Power (真・友情パワー, Shin Yuujou Pawaa) and his own Kajiba no Kuso Djikara prototype called Gouka no Kuso Djikara (業火のクソ力, Fiery Inner Strength) (Ganso Kajiba no Kuso Djikara (元祖・火事場のクソ力, Original Burning Inner Strength) in the anime).

Ataru was born the eldest son of the Royal Kinniku Family and was first in line to become the next king of Planet Kinniku. But Ataru grew tired of their life of constant training, and left home to let his brother grow up to be the next ruler of planet Kinniku. Throughout Kinnikuman's career as a Seigi Choujin, Ataru was watching him, hoping he would learn the value of friendship. Eventually, Kinnikuman had proved himself worthy to inherit the throne after winning numerous championships and defeating many powerful evil choujin. However, five other "Kinnikuman" came forward claiming to be the true heir to the throne of planet Kinniku--they had all been born in the same hospital, and because of a fire they had been mixed up so the true heir might have been misplaced in the chaos. In truth, they had been chosen as the Five Fated Princes by five evil gods who feared Kinnikuman's power should he assume the throne. A survivor series tournament was organized to determine the true ruler.

Ataru went to Fujiyama and killed one of the Princes, Kinnikuman Soldier (キン肉マンソルジャー), who'd been selected by the God of Brutality, and stole his mask to be able to compete and help his younger brother prevail. He asked Buffaloman, Brocken Jr. Ashuraman, and The Ninja) to join his team, but they refused until they saw him save a little boy from an Evil Choujin. Calling themselves the Choujin Blood Brigade (超人血盟軍, Choujin Ketsumeigun), they were given a buy into the second round and headed for Nagoya Castle, where they were pitted against Team Phoenix. After both The Ninja and Ashuraman lost to Satan Cross, Ataru, Brocken, and Buffaloman met Kinnikuman Super Phoenix, Prisman, and Mammothman in a six-man tag match. The match took place in a floating cube with three separate rings on it.

During the match Ataru used the Face Flash and Niku Curtain, causing Mayumi and Sayuri to figure out his identity. He also spoke to Suguru of True Friendship Power. Brocken and Buffaloman managed to take Phoenix's allies out of the match at the cost of their lives, causing Ataru to hit Phoenix with a fury of his teammate's techniques. However, Super Phoenix tore Ataru's page out of the Muscle Prophecy Book and had Mammothman burn it. While disappearing, Ataru used a Muscle Spark on Super Phoenix to show his brother a move powerful enough to defeat Super Phoenix. Super Phoenix quickly regained the upper hand and defeated Ataru with his Muscle Revenger, and Ataru fell to the ground and disappeared.

Neptuneman gathered Ataru's ashes and used them to save Geronimo from being killed by The Omegaman's Omega Catastrophe Drop. The ashes appeared again and held up a flag to catch Bibinba when she threw herself from the stands. Ataru's spirit, along with those of Robin Mask, Neptuneman, and Geronimo appeared during Suguru's match with Super Phoenix and restored his Kajiba no Kuso Chikara (Burning Inner Strength) to him. Ataru and the others were restored to life when Kinnikuman used his Face Flash following his victory over Super Phoenix.

Kinnikuman: Nisei

In Nisei, Ataru has no known offspring and has been gone from Planet Kinniku for awhile, having formed the team of the Chojin Untouchables (超人警察隊(アンタッチャブル)) with The Ninja. But when he hears of the situations involving his nephew Kinniku Mantarou, he returns home with The Ninja and puts Mantarou through "Kajiba no Kuso Djikara" training, sending him to a prison island to fight No Respect (Bone Cold, Hanzo, and Fork the Giant).
