Mifune vs. Hanzo Naruto: Shippûden : Season 13 Episode 12

As the Surprise Attack Division attempt to retreat the the rendezvous point, they are chased by Akatsuki's reinforcements. Summoning his salamander Ibuse, Hanzō orders it to attack. Unleashing a paralysing mist of poison, the division is rendered paralyzed and left at Hanzō's mercy. However Mifune and his division soon arrive and he deflects the would-be devastating blow. Conversing about the past and the paths they had chosen to walk, as the two trade blows, Mifune is able to break Hanzō's sickle and respirator. Finally remembering his encounter with Mifune in life, Hanzō moves towards his broken kusarigama and using the blade commits seppuku, telling Mifune that he entrusts him with his conviction. This act cuts the poisonous sac that had been in Hanzō's body since he was a child, and causes the poison to leak out and evaporate. Shocking Kabuto Yakushi, Hanzō's body ceases to respond to his orders and the legendary shinobi is soon bound and sealed.
