The Bio-Men launched a surprise attack on Gohan, who they outnumbered and quickly overwhelmed. Piccolo managed to overpower the Bio-Men even killing one with a Mouth Energy Wave, but was subdued by Doctors Wheelo and Kochin's other minions. The Bio-Men later fought against Master Roshi, though Roshi demonstrated that he was more than a match for them. After Roshi was distracted by Dr. Kochin, the Bio-Men got a hold of Bulma threatening to kill her if Roshi did not accompany him to Dr. Wheelo.

Voice Actors



  • Bio-Men bare a striking resemblance to Saibamen, though their bluish-gray skin and different facial features make them easy to distinguish from the Saibamen. Saibamen are also less verbal and appear to be stronger than Bio-Men. In addition, one of them is killed by Piccolo in a similar manner to the last Saibaman used by Nappa on Earth.
  • In Dragon Ball Z: Attack of the Saiyans, enemies called Experiment #3, Experiment #7, and Experiment #9 look similar to Bio-Men.
