Kagekenin & Akatsuki arc
He first appears at the meeting in Tanigakure, where he is told to collect his assignments. He and his partner, Morag, then leave for the Land of Fire in search of Naruto Uzumaki. He and Morag easily infiltrate Konoha. Through use of Morag's Shadow Imitation Technique he snares Naruto and they capture him. On their way out, they are stopped by Echo Uchiha who wants to join them. They lead Echo into the woods and Morag attacks Echo with his shadow. Seireitou Hyuga appears and stops them from killing Echo, however, Gensho arrives and they leave to seal Naruto. After the sealing they are again confronted by Ryun Uchiha and Seireitou. Byakko Kurohitsugi detonated a jutsu destroying the cave and Thorn takes Seireitou's group into the woods. There he fights Byakko. Minkai distracts Thorn causing Byakko to land a hit. Then Thorn, realizing he was beat, self destructs causing a distraction that allows Morag to escape.
Quick to anger and annoy , Thorn is a very hot-headed man. Something of a sadistic arsonist, he is not above relishing a good fight, and he often kills up his opponents in a very brutal fashion. Thorn's most distinctive trait, however, is his love of weapons. He will respect any form of them, even if it disagrees with his own.
Thorn refers to his killing ninjutsu as art, believing each kill he makes to be a significant accomplishment. Thorn is very proud of his weapons, to the point that he is simply unwilling to accept that anything could defeat it, leading to frequent overconfidence in battle.
Thorn refers to his partner, Morag, as Master Morag (サソリの旦那, Morag no Danna) out of respect for him as a fellow artist. He also admits, at least outwardly that Morag is more powerful than he was, due to the respect he has for him. In spite of this, Thorn wasn't above goading his partner. Thorn outwardly seems to respect Morag's beliefs.
