Teito Monogatari
Probably inspired by the invincible monsters of classic horror films, the cinematic versions of the character are incredibly durable and almost immune to pain. Across the films, he survives being dismembered, run through with a sword, having a hole blown through his body by magic, scorched by lightning, being impaled in the head, shot with a revolver several times in succession, and even having his entire face blown apart. In all these cases, he seems relatively unfazed and recovers extremely quickly. He is also rarely shown wielding a katana, except briefly in both "Teito Monogatari Gaiden" and "The Great Yokai War".
