Opicrengalon is the brother of Opigrad and he and his brother used to be rivals with Opitran and Opigamiicho. He knew how to not die from Opigamiicho's poison bites, but never taught anyone his trick. He was greedy and hated by many, including Weegee and Malleo. No one who wasn't a Wario/Waluigi type of Weegee hated him. One day he and his brother went missing. They were replaced by Opibon and Opiccubi. No one knows where they went.
