Rise up! Bio Robo (起て！バイオロボ Tate! Baio Robo) is the sixth episode of Choudenshi Bioman. This is notable as the final episode where Yuki Yajima both performs and voices the actions of her character, Mika Koizumi, the first Yellow4. Due to the unusual circumstances involving Yajima's departure with several episodes filmed but with incomplete post-production, the next several episodes until her final departure will be dubbed by a voice actress. In the Philippine Dub, the title of the episode changed to "The Pollution Conspiracy".
