Barnacle Orphnoch

Smart Brain Employee/Barnacle Orphnoch (スマートブレイン社員／バーナクルオルフェノク): The man responsible for causing the fires that killed the parents of Mari and later Teruo's. He was eventually fired by Kyoji Murakami for his incompetence and marked for death when his actions attracted attention from law enforcement, with Kitazaki given the task of killing him. Barnacle was unaware of this and attempted to retrieve the Rider Gear until he was killed by Faiz (Yuji Kiba)'s Grand Impact.
