Magnet Release

The Third Kazekage's unnamed kekkei genkai allowed him to convert chakra into magnetic forces. The Third studied a host of the One-Tailed Shukaku and learned to imitate the power to control sand. However, when he imitated sand techniques, he used iron powder instead, thanks to his special magnetic powers. He could use it to crush his opponents or even mold the sand into weapons. This Iron Sand can also clot up the joints of puppets, making them unusable in battle as long as the Third Kazekage's magnetic field is in effect.

When the Third Kazekage was turned into a Human Puppet, Sasori gained access to the Iron Sand weapons and imbued the sand with his poison, increasing its lethality. The puppet was later destroyed by Sakura Haruno and Sasori's grandmother, Chiyo. As the Third Kazekage's ability to convert chakra into magnetic fields was unique to himself, when his puppet form was destroyed, the kekkei genkai became lost forever.
