Sadai

Sadai (サダイ, Sadai) is an assailant who entered Land of Fire to capture Naho. He was on the national wanted list. Sadai and his group intercepted Naruto Uzumaki, Sakura Haruno and Naho. Naruto managed to defeat his comrades, but his Shadow Clone Techniques and Rasengan didn't work on him. After he captured the group, Sasuke Uchiha came and battled him. After discovering his taijutsu skills weren't enough, he used Fire Release: Great Fireball Technique to burn assailants armour, thus showing his true face. Sasuke defeated him using Chidori, and even after his defeat, Sasuke punched him severely because of his words about Itachi Uchiha and the Uchiha Clan Massacre and about weak Sasuke. Sasuke was only stopped by Kakashi, who reminded him that they should bring Sadai back for questioning. Debut: Naruto Shippūden Episode #196 (source: http://naruto.wikia.com/wiki/Sadai)
