Rōshi, who hailed from Iwagakure, became a Jinchūriki at an early age when he was tasked with controlling the power of the Four-Tailed Beast. He left his hometown to master this ability and utilized its Lava Release ninjutsu, which combined Fire and Earth chakra. Despite being captured by Kisame Hoshigaki of Akatsuki, Rōshi passed away after having the beast's power extracted from him.
