Clone One

Megatron created a clone of Dinobot's beast mode so that it could infiltrate the Maximals by masquerading as the turncoat Predacon. Because it is a real (organic) dinosaur instead of a Transformer, it cannot transform. But with the inputting of Dinobot's Core Consciousness and Megatron's programming technique, the clone proved much more intelligent than a normal dinosur. However, this clone doesn't have nearly the sense of honor of the original.
