Needing the Pillar Men to surpass Dio, Araki said he had to up the ante to the level of gods, and so based their designs on Roman statues, Egyptian sphinxes and Japanese "nio" statues to give them godlike features. Araki designed Kars with a turban to show his superior intelligence and that he is their king. He said that if you compared the Pillar Men to "Mito Kōmon", Kars would be Kōmon, Esidisi would be Suke-san, and Wamuu would be Kaku-san. Kars' ability Brilliant Bone Blade is a "Light Mode" because Araki thought a shining blade would be a godlike technique and would visually express that defeating him was impossible. He speculated that many readers were probably reminded of the similar Reskiniharden Saber Phenomenon technique from his series "Baoh", and admitted that aspects of Kars' goal to become the ultimate being somewhat overlapped with the earlier work. Visually speaking, Araki also really enjoys drawing flesh and blade merge as something that is only possible in manga.
