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