Hiruko (missing-nin)

is the main antagonist of Naruto Shippūden 3: Inheritors of the Will of Fire. He is a missing-nin of Konohagakure who wishes to plunge the world into a Fourth Great Shinobi World War and then conquer it.

Appearance
Hiruko appears to be a white-haired boy with red eyes, dressed in an oversized, high-collared coat wrapped with leather straps. Most of his body is covered in bandages, including his mouth and arms. Despite his youthful appearance, he is actually closer in age to the Sannin.

Plot Overview
A contempary and former friend of the Sannin, Hiruko wished to become a strong shinobi, yet was born with no natural special abilities. To overcome this disadvantage he developed a technique known as Chimera no Jutsu, which would allow him to absorb the chakra of other ninja, as well as any Kekkei Genkai they may possess. Some time after the Third Great Shinobi World War, Hiruko divulged his findings on Chimera no Jutsu and left the village as a missing-nin.

Dozens of years later, ninja possessing Kekkei Genkai begin disappearing from Kumogakure, Iwagakure, Kirigakure, and Sunagakure, leaving Konohagakure as the suspect and prompting rumors that they are preparing to rebel against the Land of Fire. While on a mission flying over Mount Shami, Sai falls under attack from a mysterious, bird-like monster. Team Kakashi arrives to rescue him, but encounter wolf-like monsters, and though they manage to escape, Naruto is injured. When Konoha ANBU are dispatched to investigate, they encounter Hiruko and his followers, Ichi, Ni, and San. Hiruko reassures his followers that there's nothing to worry about, then quickly dispatches the ANBU squad with Chimera no Jutsu, absorbing their Earth-nature chakra and using it manipulate the mountain itself, crushing them.

With the other nations amassing troops on the borders of the Land of Fire and threatening to invade, Hiruko uses a genjutsu to project himself in the skies over Konoha and deliver a message, announcing that he intends to obtain the Kekkei Genkai of the Land of Fire, becoming immortal and virtually invincible. With the combined power of Kekkei Genkai of the Five Great Nations, he plans to instigate a Fourth Great Shinobi World War and rule the world.
