Brainmaster

Brainmasters were a form of Transformers available primarily only in Japan, and similar to the concept of Headmasters. Instead of having the pilot form the entire head, as with Headmasters, the pilot of a Brainmaster would form the face of the larger robot.

Members of the Brainmaster sub group include:

Star Saber [[Blacker]] Laster
