The Choudenshi Biomen (超電子バイオマン Chōdenshi Baioman), individually known as the Biomen (バイオマン Baioman), are the main characters of Choudenshi Bioman. They are composed of five descendants of five young people showered with Bio Particles five hundred years ago by Bio Robo of the destroyed Bio Star. These five descendants were chosen by Peebo and Bio Robo to become the Bioman team in order to protect the Earth from the Neo Empire Gear, an organization led by the mad scientist Doctor Man.
In Turboranger, the Biomen joined up with Battle Fever, the Denzimen, the Sun Vulcan, the Goggle V, the Dynamen, the Changemen, the Flashmen, the Maskmen, and the Livemen, to stand behind the newest Sentai, the Turborangers, as they faced off against the Hundred Boma Tribes.
Years later, the Space Empire Zangyack invaded Earth. This threat was so great that all of the first 34 Super Sentai, including Bioman, were needed to oppose them. The 34 Sentai put up a valiant fight against the ground forces, but when the Zangyack fleet itself attacked them, Akarenger told everyone to combine their powers and save the Earth. This destroyed the Zangyack fleet and resulted in the loss of their powers, which resurfaced as Ranger Keys, that were dispersed throughout the universe.
In Super Hero Taisen, the Biomen, among the majority of the Super Sentai heroes, were caught up in the "Super Hero Taisen" incident. They were presumably sent to the dimensional riftIcon-crosswiki, under the pretense of being defeated, by Kamen Rider Decade while he was apparently hunting the Sentai teams. When his and Captain Marvelous' ruse was revealed, Bioman appeared with the other Super Sentai through the dimensional wallIcon-crosswiki, they then fought alongside all the other Sentai teams and Kamen RidersIcon-crosswiki against the alliance of Dai-ShockerIcon-crosswiki and Dai-Zangyack.
