Panther King

A powerful demon slain by the Great Dog Demon (Inuyasha and Sesshomaru's father) decades ago. The Panther Devas hope to revive him, but inadvertently sacrifice themselves to bring the demon back to life.

History
Two centuries prior to the current point in the Sengoku period, the Panther Devas invaded from the west and tried to conquer the area and subject all demons to their rule. To avoid the abominable effusion of blood—both human and demon alike—Inu no Taishō and the Panther King dueled one-on-one, with the former soundly defeating the latter to his death.

Two hundred years later, the Panther King's followers (possibly children, it's somewhat unclear) put into play a plot to bring the Panther King back to life using shards from the Shikon Jewel. They bring his mummified corpse to a secret castle town where they plan to revive him and, from there, finish the war they began long ago.

After awakening from his two-century sleep, the Panther King prepares to devour the villagers to complete his restoration, only to have Inuyasha thwart him from taking his sacrifices. Impatient with their attempts to provide him with "a life and a soul", he kills Koran, Shuran, and Shunran, devouring their essences greedily as the remaining Kōran (whom he had also tried to kill) watches on in horror. His body restored, the Panther King immediately takes on Sesshomaru and Inuyasha, the sons of his longtime rival, and proves too much for them.

After assaulting Sesshomaru and putting Inuyasha in his place, the Panther King is undone when Sesshomaru cleverly uses Tenseiga to revive the three Panther Devas whom he devoured to regain life. When their souls and lives return to their bodies, the Panther King's power is drained. Inuyasha finishes him off with a blow of the Kaze no Kizu and reclaims the jewel shards from his neck. After he dies again, the Panther Devas lose all interest in war and, in light of his betrayal, vengeance on their master's behalf. What happened to his remains after this is never specified, but it's likely that the Panther Devas left its disposal to the villagers.

Powers and Abilities
The Panther King is considered to be a Daiyōkai, and is therefore quite powerful in his own right.


 * Strength - The Panther King is enormous, and has strength proportionate to one his size.
 * Horns - The Panther Long has one horn in the center of his forehead and other such portrusions over his body. He uses these to stap and batter his foes to great effect. He was shown to knock Sesshomaru back quite a distance and actually hurt him in the process.
 * Claws - The Panther King has large claws which he uses to scratch at his opponents. He can also launch these from his fingers at great speed and force and generate new ones instantly, making them effective projectile weapons.
 * Lightning - The Panther King can generate lightning and shoot it at his opponents. Whether this ability is one of his own or if it came from absorbing Shunran's essence is unknown.

Note: the Panther King had the power of three Shikon Jewel shards after his resurrection, so whatever power they lent to his original abilities is unclear.
