Onimengo is an oni monster working for the Dogma Kingdom and an antagonist in Kamen Rider Super-1.
Onimengo was ordered by General Megirl to kidnap children and indoctrinate them to Dogma teachings, eventually establishing a giant education system that will sweep throughout all of Japan. His victims included Ryo Kusanami and his friends in the Onigashima forest. He also at one point displays explicit pedophilia though Megirl called him on it. He was destroyed by Super-1's Super Rider Lightning Drop.
