Fuguki Suikazan

The previous wielder of Samehada was a high-ranking shinobi of Kirigakure and a former member of the Seven Ninja Swordsmen of the Mist. He was the superior of Kisame Hoshigaki.

Background
He assigned Kisame to the secret Intelligence Squad mainly as a bodyguard, ordering him to protect his comrades. However, he stressed that the codes that were important to the village are far more worthy than their lives. With this set of priorities, Kisame resolved to massacre his own teammates when they were in danger of falling into the hands of Ibiki Morino during a mission to protect such valuable information.

Later, this superior was revealed to have been leaking information to enemies, and was killed by Kisame when he let his guard down during a meeting, with his corpse visibly impaled by sharp implements tied to chains. Kisame would then take Samehada for himself, becoming a member of the Seven Swordsmen, Yagura's direct subordinate and Madara Uchiha's accomplice.

Appearance
Samehada's previous wielder was a large shinobi. He had small round eyes and like all the known members of the Seven Ninja Swordsmen of the Mist, sharp jagged teeth. He had long hair that reached into his back with some pinned up at the top. He also had facial marking that gave him the overall appearance of a tiger shark. Attire-wise he wore the standard striped jumpsuit of Kirigakure, a black outfit over it as well as a white cloak/robe over it and Samehada strapped over his shoulder. He also wore the Kirigakure forehead protector and standard shinobi sandals, and as with all the swordsmen of the previous generation, he had bandages wrapped loosely around his neck.

Shinobi World War Arc
He, along with the previous generation of the Seven Ninja Swordsmen of the Mist, were summoned by Pakura and Gari under Kabuto's Summoning: Impure World Resurrection technique in order to overwhelm the Third Division forces.

Trivia

 * literally means "puffer fish demon", and means "watermelon pile"; like all members of the Seven Ninja Swordsmen, his surname is derived from a type of produce.
