Saibaman Character Facts

Saibamen were created by a Saiyan scientist using biotechnology.[1] They made their way into Frieza's Planet Trade Organization through the Saiyans, and were then used after they learned how to understand orders.[2] They became a common tool of the Planet Trade Organization, which frequently used Saibamen in training exercises for warriors, as shown when a young Vegeta effortlessly defeated five Saibamen at the age of five.[3] 
The Saibamen possess only enough intelligence to understand orders given to them by their leaders, thus they will never revolt. Those in use by Nappa and Vegeta are a more advanced model developed in Age 737, and their Power Level is 1,200.[1] Vegeta and Nappa used several of those Saibamen during the Tritek war, although only six remained.
