Kako is a Fabrication built to serve Ku and to command the Akuta, an artificial being made in the name of Onoki's dream of lasting peace for Iwagakure and the wider shinobi world. A battle-hungry fighter armed with Dust Release, he dies when his failing body gives out mid-duel against Boruto.
Bandages wrap Kako's hands and face, matching those worn by his fellow artificial humans. He has red hair and grey eyes, and dresses in a purple tunic pulled over a sleeveless black bodysuit.
Kako runs hot and impatient, craving the thrill of a fight and never happier than in the thick of one. Like the other Fabrications, he is intrigued by how humans relate to one another and enjoys reading about it. That same hunger for combat makes him difficult to command, prone to defying orders and to driving himself well past his own limits.
As a Fabrication, Kako's body outstrips any ordinary human. He is nimble and hard to pin down, skilled enough in taijutsu to hold his ground when three opponents come at him at once, and durable enough to absorb a fully charged chakra-enhanced punch from Sarada and keep going. Because his design folds in some of Onoki's genetic material, he commands the Dust Release Kekkei Tota, the uncommon fusion of earth, wind, and fire.
With it he can loose cubes of energy that disintegrate whatever they touch, whether fired as a rapid volley of small projectiles or shaped into one enormous block, and he rounds out his arsenal with Earth Release rock clones and crushing walls. The drawback is steep: after each Dust Release attack he cannot manage any other ninjutsu for roughly twenty seconds without tearing up his own body. During his fight with Boruto he chose to push past that limit anyway, unloading a barrage of Dust Release, and though he had the boy and his allies cornered, his body gave out for good and killed him.

We ranked the six most popular women of Naruto from worst to first, and our number one is going to start a fight. The official poll got it wrong....

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....
Kako is an artificial being called a Fabrication, created to serve Ku and command the Akuta in Iwagakure as part of Onoki's dream of lasting peace.
Kako commands the rare Dust Release Kekkei Tota, a fusion of earth, wind, and fire that lets him fire disintegrating energy cubes, alongside Earth Release rock clones and crushing walls.
Kako died when his body gave out after he pushed past his own limits, unloading a barrage of Dust Release attacks during his fight with Boruto Uzumaki despite the technique's steep physical cost.
Using Dust Release leaves Kako unable to perform any other ninjutsu for about twenty seconds without tearing up his own body, a risk he ignored in his final battle.
Kako has red hair and grey eyes, wears bandages on his hands and face like the other Fabrications, and dresses in a purple tunic over a sleeveless black bodysuit.
