―Biomen announcing their arrival[src]

The Choudenshi Bioman (超電子バイオマン Chōdenshi Baioman), individually known as the Biomen (バイオマン Baioman), are the 8th Super Sentai, composed of five descendants of five young people showered with Bio Particles five hundred years ago by BioRobo of the destroyed Bio Star. These five descendants were chosen by Peebo and BioRobo 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.

Team History

Bioman come to cheer on the Turborangers.

Bioman joined up with Battle Fever, Denzimen, Sun Vulcan, Goggle V, Dynamen, Changemen, Flashmen, Maskmen, and the Livemen, to stand behind the newest Sentai, the Turborangers, as they faced off against the Hundred Boma Tribes. Tvicon.png TV STORY-Counting on You! Turboranger


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, which were dispersed throughout the universe.

The keys were collected by AkaRed, and later utilized by the 35th Super Sentai, the Gokaigers, a group of five people from different planets who came to Earth in search of the Greatest Treasure in the Universe. Tvicon.png TV STORY-Ep. 1: The Space Pirates Appear When the Gokaigers joined forces with the Goseigers against the revived Black Cross Führer, now known as the Black Cross King, they were addressed by Akarenger, along with several other representatives of past Sentai teams, including Shirou, who told the Gokaigers and Goseigers to not be afraid, that when evil approaches the earth, they must bring everyone's love together. As with the other legends present, he granted the greater power of his team to the Gokaigers.

Super Hero Taisen

The Biomen, alongside the Flashmen, Changemen, Dynamen, and Turborangers, emerge through a dimensional wall.

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.png, 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.png, they then fought alongside all the other Sentai teams and Kamen RidersIcon-crosswiki.png against the alliance of Dai-ShockerIcon-crosswiki.png and Dai-Zangyack.

The Space Pirates Return

The Gokaigers made use of the Ranger Keys in their fight with the Zyuohgers and Bangray.

Evidently, the Biomen loaned their Ranger Keys - at the request of Gai Ikari - to the Gokaigers whom had temporarily returned to Earth to find and bestow the Great King's Credential to the Zyuohgers. Tvicon.png TV STORY-Ep. 28: The Space Pirates Return Their powers were returned when the Gokaigers left for space once more having achieved their quest.
