Biomen (バイオマン, Baioman) are blue, humanoid creatures created by Kochin. They bear a striking resemblance to Saibamen, but are colored blue, have a different body structure, and can speak, though not very fluently. Just like the Saibamen, they can self-destruct, which one of them uses against Yamcha. All Biomen are voiced by YamatoSFX.
- It's noticeable that Biomen are actually weaker than Saibamen as Master Roshi was able to easily defeat them and that Yamcha has survived their explosion.
