Captured Peebo (つかまったピーボ Tsukamatta Pībo) is the seventh episode of Choudenshi Bioman. This is the first of a two-part story involving Joy, a friend of Peebo from planet Bio and more regarding the true fate of the doomed planet. Productionwise, this is likewise the first episode that begins a peculiar transition for Mika Koizumi (Yellow4), where Yuki Yajima appears in the Sentai footage but is not voicing her own dialogue; instead being voiced by anime voice actress Mayumi Tanaka. This is a matter which will culminate with Bioman's tenth episode.
