Iwakyō

is a shinobi from Iwagakure and the eldest brother of the village's Three Brothers group.

Personality
Iwakyō is seemingly cruel and relentless like his brothers.

Appearance
He is a large man, with a bald head and dark eyes. He wears the standard Iwa-nin flak jacket, with his forehead protector around his neck, and the standard pants with a lapel. Like Iwazo, he wears bandages around his arms and black, spiked wristbands.

Abilities
He seemingly possessed a great deal of brute force able to rupture a large portion of ground with a single strike. He also proved to be an observant adversary, being able to spot a Body Replacement Technique in the darkness of night.

Adventures at Sea Arc
As Iwakyō and his brothers pursue Kosuke through the night, in order to retrieve intel that he had stolen from them, the brothers eventually corner him deciding to interrogate him for information on Konohagakure instead. His plans are however thwarted by the appearance of Team Asuma and their Formation Ino–Shika–Chō. When Chōji Akimichi used the Human Bullet Tank to stop them he was caught by Ino's Mind Body Switch Technique and was forced to fight Iwaji and Iwazo. He was then knocked out by Chōji.
