Rōshi

is the Jinchūriki of the Four-Tailed Beast. He was captured by Kisame Hoshigaki of Akatsuki and later died as the result of having the Four-Tails extracted from his body.

Background
Rōshi was imbued with the Four-Tails at a young age. Because he was not affiliated with a shinobi village, he went on a journey to understand and control the excessive power of the Four-Tails.

Hunt for Uchiha Arc
During his journey, he encountered Kisame and battled him. Even though Rōshi used the Four-Tails' power, he was defeated. Later, Akatsuki extracted and sealed the Four-Tails, which led to Rōshi's death

Abilities
By borrowing the Four-Tails' power, Rōshi was able to use its Lava Release ninjutsu, a combination of fire and earth-based chakra.
