Bio-Men (バイオマン) are disposable warriors utilized by the scientists Dr. Wheelo and Dr. Kochin, when they initiate some of their plans.

The Bio-Men first appeared in the movie Dragon Ball Z: The World's Strongest, first seen when they 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.

Other than The World's Strongest, the Bio-Men also make a cameo appearance in Dragon Ball Z: Fusion Reborn as one of the escaped Hell residents.


The Bio-men were strong enough to harm Gohan when they ambushed him however the combined might of four them together were easily beaten by Master Roshi.

The movie pamphlet for Dragon Ball Z: The Tree of Might states that Bio-Men have power levels of 1,000.

  • 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, as Master Roshi (who was far weaker than a Saibaman) was able to defeat several Bio-Men at once relatively easily. In addition, one of them is killed by Piccolo in a similar manner to the last Saibaman used by Nappa on Earth.
  • In the video game Dragon Ball Z: Attack of the Saiyans, enemies called Experiment #3, Experiment #7, and Experiment #9 look similar to Bio-Men.
