Hidan

Hidan is a character from the anime series 'Naruto.' He is a member of the Akatsuki organization and partners with Kakuzu. He is also a devout follower of the Jashin religion. Hidan possesses immortality, which makes him exceptionally difficult to defeat in battle. His fighting style primarily revolves around a special curse ritual. By obtaining and consuming his opponent's blood, he shares damage with them. Once the ritual is complete, any harm Hidan sustains is also inflicted upon his opponent. This allows him to fearlessly attack, utilizing this mechanism to defeat enemies. Hidan's personality is arrogant, cruel, and bellicose. He enjoys taunting his adversaries, relishing in the sadistic pleasure of combat. He firmly believes in the Jashin religion, frequently invoking the name of 'Jashin' and behaving like a fanatic. Despite his immortality, Hidan is not invincible. His weakness lies in his inability to perform the ritual, and thus loses his regenerative power. Additionally, while his body cannot die, it becomes unable to move if his head is severed. Hidan was eventually defeated by Shikamaru's strategizing and was buried in a deep forest from which he could not escape.
