Plot overview
He and his subordinates, Fugai, Kamina, and Ranke, attacked Temujin's village (although Temujin didn't know about it at the time). The Stone of Gelel, which had life-giving powers, is located south of the Land of Wind. By claiming that he wished to establish a utopia, he was able to recruit many followers. However, this was a facade for his true desire: to use the Stone of Gelel to become all-powerful. He was able to turn Temujin's fellow orphans into animated suits of armor, enabling him to build an army. After he obtained the Stone of Gelel, he underwent a monstrous transformation into a grayish humanoid. However, thanks to Temujin's help, Naruto Uzumaki was finally able to kill him with the Twin Rasengan.
