Sasori is Deidara's partner in the Akatsuki and a major antagonist in Season 20. Sasori was present during Piccolo's battle with Deidara, and later Nagato. Sasori was later seen trying to capture Killer B with the rest of the Akatsuki, and flees when Tobi is crushed. Sasori, Deidara, and Kisame later go to Smash City to get the jinchuriki (Naruto Uzumaki and Killer B) while Madara is healing. However, he is killed by Yami Bakura and is reanimated by him shortly afterwards. Sasori is revived in Season 22 due to the improper ressurection of The Offspring of Zorc.
Sasori initially hid inside his Hiruko puppet. After the attack on the Hidden Cloud Village, Sasori discarded Hiruko.
Sasori is loyal to the Akatsuki's goals, though whether he is loyal to Nagato or Tobi is unclear. Sasori also has views on art that are different from his partner Deidara.
