Han

was a shinobi from Iwagakure and was the jinchūriki of the Five-Tailed Dolphin Horse, as well as the physically largest jinchūriki, easily standing a head taller than Killer Bee. The Five-Tails has been captured and sealed by Akatsuki, causing Han's death when the beast was extracted. Also, it is mentioned by Deidara that Han was one of the first Jinchūriki to be captured in the anime. Han fought using an unamed Steam-based Ninjutsu.

Appearance
Unlike most other ninja seen in the series, Han is heavily armored, wearing a so-called with a furnace on the back that emits steam. His armor extends all the way to the bottom half of his face, covering it up. Aside from his red armor, he also wears a red kasa (conical straw hat) that seems to be composed of metal. Over his armor, Han wears a black gi, with the sleeves seemingly torn off and black gloves.

Personality
Not much is known about Han's personality, other than he loathed humanity according to the Akatsuki, due to being neglected and hated by his village.

Trivia

 * In order to prevent the jinchūriki from turning traitor, it is tradition for the host to be selected from the family of the village's own Kage. It might be implied that Han was somehow connected with one of the Tsuchikage.
