Abilities
Jiga apparently has the exact same genetic mutation that the Third Kazekage possessed, namely that of being able to convert his chakra to magnetism. However his ability was no where near as powerful as the Third's who could create massive constructs out of his Iron Sand and mimicked the powers of Shukaku and his Jinchuriki. His ability was also different in that he learned how to use his magnetism conducted through his own Iron Sand 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 was also extremely proficient with a Meteor Hammer with a steel cable enhancing his ability by magnetizing the weight and using it to home in on opponent's metallic objects (such as a Hitai-ite). He had a glaring weakness to those who could exploit it. Every once in a while during the course of the battle he had to stop to tap himself. Whether he was using Juken on himself or grounding himself out is debatable but he needed to do so to stop the flow of magnetism. As Hinata revealed when she defeated him without the ability to turn off his own magnetism he would be swallowed by all magnetically sensitive objects. in the end he was swallowed by magnetized iron sand.
