Kaneki Ken is the main character from the anime and manga series Tokyo Ghoul. After a near-fatal encounter with a ghoul, he undergoes surgery that transforms him into a half-ghoul. This change grants him enhanced strength, speed, and regenerative abilities, allowing him to survive in a world filled with dangerous ghouls. In his ghoul form, Kaneki's appearance alters significantly. His skin becomes pale, and he develops sharp, elongated claws. His most notable feature is his ghoul eye, which turns a striking red with a black sclera. This transformation symbolizes his struggle between his human side and his new ghoul identity.
