Rogone is a somewhat slim man with long hair, sunken eyes and a thin moustache. He also has several traits that resemble a Japanese Oni, including an underbite with two sharp teeth poking out from his lower jaw, a pointed horn protruding from the middle of his forehead that curves upwards and sharp fingernails.
In his transformed state, Rogone gains a large amount of muscle mass, as well as a significant amount of belly fat. He sprouts two larger horns from the sides of his head and his teeth and jaws grow as well.
Iron Club (アイアン・クラブ Aian Kurabu?): Rogone can transform into an Oni-like creature with immense physical strength, standing at 229cm tall. In this form he can then transform both his arms into spiked clubs strong enough to crush bedrock.
