Kafka Hibino- Appearance: Kafka is a tall man with dark brown spiky hair, large eyes with small irises, thin eyebrows, and a mild goatee on his chin, he sports a rather muscular frame except for his slightly pudgy belly and he usually has a jovial expression on his face. Working for Monster Sweeper Inc., Kafka once regularly wore the company's uniform; it is a grey coverall with a red Monster Sweeper logo on the right side of the chest. Kafka's Kaiju form is mostly covered with coal-black scales and plates, cyan energy sometimes glowing from between the cracks (most notably when he is charging a powerful attack). However, his head, spine, and clavicles appear to be made from exposed bone, resulting in these features being a contrasting white. Large plates with dorsal spines cover the back of his head and neck above the shoulders with the very top piece being white. As for his head, it has been described as a 'demonic skull-face' with two short, thick horns, a hole for a nose, and sharp, exposed teeth that extend down his neck. His eyes have black sclera with a cyan iris. Seemingly originating from them are several cracks, the left eye having several chunks of the 'mask' missing on the lower left part. His Kaiju form resembles the armor and mask of the fallen warriors in Meireki-Era, which were powerful Amerasian soldiers. When out of control, some of the Kaiju form's features become more pronounced. Such as; his general size relative to people, elongated horns, more predominate dorsal plates, mouth extending further down his neck, and eyes turning entirely cyan (without pupils or a definable beginning or end to his sclera). The Kaiju form's features became even more pronounced in the anime: four extensions on the back position in a cross shape, a greater height that forces a crouched posture, and the cyan energy turning red. After Kafka learned to control the berserk state for one minute, pupils will briefly appear when he speaks in that form. After having his heart converted into a Core to deepen his connection with the Mysterious Larva, Kafka's Kaiju form undergoes a metamorphosis by shedding the black scales and plates. His body is now white while still retaining the energy cracks on his upper body, the horns on his skull-face have slightly grown, curved inward and possess a set of two small eyes along each horn's curve, and his back now sports four maple leaf-shaped dorsal plates. After the final battle with the Meireki Era Daikaiju[, Kafka's Kaiju form reverted back to its initial form after Isao Shinomiya transferred his heart to Kafka from merging with the Mysterious Larva.
