Fūma Clan

The is a renowned ninja clan, famous in at least Amegakure and the Land of Fire, though it is unknown where they originate from. They are well-known as an aggressive clan and fight using their characteristic giant Fūma Shuriken; a large, four-bladed weapon said to possess preeminent sharpness.

Overview
The type of shuriken they use has spread beyond the Fūma clan though, as Sasuke Uchiha used one during his fight with Zabuza Momochi and several other shinobi have been seen using them since.

While travelling the world during his younger years, Jiraiya faced a member of this clan in battle. Although the outcome of this battle is unknown, Jiraiya did manage to give this Fūma member a scar on his forehead. Years later, Jiraiya faced this same ninja again. This time, the Fūma member had been made into one of Pain's bodies. The scar on his head allowed Jiraiya to recognise him and subsequently all of Pain's other bodies as well.

Name
The name literally means "Wind Demon" and comes from a real-life ninja clan founded by the legendary Fūma Kotarō. This Fūma Kotarō is said to have defeated and killed the equally legendary samurai Hattori Hanzō (who gave his name to Hanzō, who was in turn defeated and killed by Pain).

Trivia

 * Another Fūma clan is featured in the anime. It is unknown whether the Fūma clan from the anime and the manga are the same, but it is unlikely, since the names are written differently and the clans' descriptions differ.
