Biomen

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 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.

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 asRanger Keys, that were dispersed throughout the universe.
