Goshinki

was a large, horned ogre yōkai with the ability to read minds, and was an incarnation of the Spider-Hanyō Naraku. He was extremely agile, powerful, and possessed teeth strong enough to break the Tessaiga, the fang of Tōga.

History
Goshinki's task was to slaughter an entire village to lure the badly wounded Inuyasha there. Using his ability to read minds, he countered Inuyasha's every attack, eventually seizing the Tessaiga in his fangs and shattering it into pieces. Though Inuyasha was near death, the absence of the Tessaiga allowed Inuyasha's yōkai blood to take over. Because in his full-yōkai form Inuyasha's only thoughts were the joy of killing, Goshinki was unable to read Inuyasha's mind which made him an easy kill. Inuyasha easily lopped off Goshinki's arm after this transformation, and soon he brutally tore Goshinki to shreds with his claws, leaving only his head behind.

Later on, Inuyasha's half-brother Sesshōmaru has an evil yōkai sword named Tōkijin crafted by Kaijinbō from Goshinki's fangs. However, to make Goshinki's fangs purposeful in forging, Sesshōmaru used his Tenseiga to revive Goshinki's disembodied head, but he presumably died shortly after, if not immediately as his fang's quality has been restored but his head showed no response to being revived.

Personality
Goshinki was a rather cruel and destructive yōkai; he ferociously searched for the only surviving children of the village he massacred, insisting that he would slaughter everyone and everything (even the cows, chickens and horses) in the village, as he was ordered to do by Naraku. When attacking his prey, Goshinki had a habit of toying with them; using his mind reading ability, Goshinki would often bring up exactly what the victim was thinking in order to frighten or unsettle them, such as when he coldly told the children he attacked that he had already devoured their parents, and that they should look inside his mouth to see for themselves.

Powers & Abilities

 * Super Strength: Goshinki typically possesses enhanced strength for someone of size, able to easily defeat Inuyasha and fling him about whilst causing serious injuries.
 * Super Speed: Despite his size, Goshinki wields surprising agility, effectively dodging and countering Inuyasha's attacks. He leaves afterimages in his wake, much like Sesshōmaru.
 * Telepathic Prediction: Goshinki's most terrifying technique is the ability to invade other people's minds, reading their most inner thoughts to discover their weaknesses and counter any attack on him. However, Goshinki's power is ineffective against a full-demon Inuyasha due his thoughts being primitive with an absolute bloodlust.

Trivia

 * Goshinki's powers are based on the Yōkai, who attacks his prey through similar mind-reading skills.
 * The last kanji in Goshinki's name, 鬼, can be translated as "Oni" or "Demon" which did resemble his oni-like physical appearance.
 * He and Kagerōmaru are the only incarnations of Naraku to not have human forms.
