Jiga

was the second oldest brother from the Criminal Brothers trio.

Background
Jiga, along with his brothers, established a coup d'etat, which resulted in the death of the Land of Vegetables' daimyō. After their rise to power, the three brothers betrayed their allies, which included greedy and disloyal courtiers they had recruited, and slaughtered them all. The brothers themselves were distrusting of each other, and plotted to kill off the others in order to have more wealth and power for themselves.

Abilities
From an early age Jiga had ingested iron, which eventually allowed him the ability to magnetise his body and other metallic objects. He could use his magnetism to disrupt the electrical impulses in the brain, effectively blocking a person's entire nervous system from functioning. He was also able to rip metallic ore and rocks from his environment to make makeshift projectiles to overwhelm an opponent. He turns this ability on and off by slapping his stomach. This ability had a glaring weakness to those who could exploit it: occasionally, during the course of a battle, he had to pause to stop the flow of magnetism. If he remained the ability on for too long, he would attract all nearby ferrous objects against his will.

Jiga was extremely proficient with a kusarigama, enhancing his ability by magnetising the weight and using it to home in on an opponent's ferrous metallic objects (such as a forehead protector). He was also physically strong, seen when he was easily able to swing Naruto, who was stuck at the kusarigama around, and when he almost defeated Hinata with one single punch in the stomach.

Land of Vegetables Arc
His brother Ruiga was defeated by Naruto, Chōji, and Yurinojō. Jiga then finished Ruiga off himself by burying him in magnetic rocks, stating that one less person sharing the wealth meant a larger share for himself and Renga. After he killed Ruiga, he fought Naruto and quickly defeated him. Hinata arrived soon after Naruto's defeat, and was able to defeat Jiga. She did this by inserting an electric current in his chakra effectively reversing its flow, causing him to become a powerful magnet. He is then sucked into an iron sand vortex, which killed him.
