Kamen Rider OOO is the protagonist Kamen Rider who appears in the Japanese tokusatsu drama "Kamen Rider OOO". It exists to seal away those who are greedy. Since Hino Eiji has no desire, he will not go berserk under normal circumstances (the desire represented by the wing horn violent combination is zero, so he will only go berserk when using the wing horn violent combination. Later, he was restrained by Hino Eiji, but the use time was too long. And will still go berserk when thrown into the dinosaur core coin)
