Which of these robots is in control (or even sentient at all) is unknown.
- Cybertron Base (Contest prize, 2004)
- Master came only with Cybertron Base, who was First Prize in a Robot Masters contest where only 10 were awarded. As Cybertron Base is completely identical to the retail-release Car Robots Brave Maximus toy, Zebres is identical to the Cerebros robot. He transforms to the head module to Zebres, but does not need to be attached to allow Zebres to form Base's head.
