Sandaime Kazekage

三代目風影

The Third Kazekage was formerly the leader of Sunagakure, although his real name remains unknown. He possessed the unique ability to manipulate his chakra and transform it into magnetic forces, rendering him immune to all metallic weapons. After studying the then-host of Shukaku, he replicated its sand-manipulating powers by combining his magnetic chakra with iron powder, creating the Iron Sand technique. It was due to this specific ability that he was recognized as the strongest Kazekage in Sunagakure's entire history.
Sasori kidnapped and killed the Third Kazekage to convert him into a Human Puppet. The effort required for the Third's capture made him Sasori's favorite puppet. Sunagakure was unaware of this and searched earnestly for his whereabouts. Their actions are suggested to have sparked the Third Great Shinobi World War. Following the war's outbreak, the village was forced to abandon the search and appoint a Fourth Kazekage, although further search attempts would occur in later years.
The Third's fate is revealed during Sasori's battle with Sakura and Chiyo, when Sasori deploys the Kazekage puppet against them. After a prolonged battle, Sakura managed to destroy the puppet.
