Primal Prime

Primal Prime is a fictional character from the Transformers toy and story lines. He was created for the Beast Machines toy line, and is a repaint of Optimal Optimus.

Bio
Shortly after the Maximals and Predacons left Earth, the evil Tarantulas resurfaced, planning to steal the Autobot Matrix of Leadership and destroy the Autobots and Decepticons. To stop him, the alien race known as the Vok sent the binary spark of Tigerhawk back to Earth to separate into Tigatron and Airazor. They then set out to create a new Emissary, one to be known as the Living Matrix.

Aboard the buried Ark, the Vok discovered an abandoned control suit used by the Predacon Quickstrike to manipulate Optimal Optimus. Using the Matrix of Leadership, contained within the nearby dormant Optimus Prime, they made the suit into a Maximal. This Maximal was Primal Prime, a robot with all the knowledge of the Matrix and characteristics identical to those of Optimal Optimus. Gathering a force of warriors to his aid, Primal did battle with the forces of Tarantulas.

After that conflict, Primal and his crew headed for Cybertron. However, they arrived to find the planet under the despotic rule of Megatron and his Vehicon horde, along with their virus weapon. Fortunately, they met up with the last remnants of the Wreckers task force: the Maximal scientist Apelinq and the ancient Autobot Rodimus Prime. After being inoculated for the virus by Apelinq, who ended up lost in time, Primal Prime assumed command of the Wreckers. He kept this role even when Apelinq returned, adding several Decepticons to the ranks of the Wreckers.

Primal Prime and fellow Wreckers came to the aid of Optimus Primal, who was under attack by Vehicons forces. After a subsequent meeting with the Oracle, Prime and his forces departed Cybertron to seek allies, preparing to meet at the Nexus. However, they first had to overcome the forces of the diabolical Cryotek.

Universe
According the Transformers: Universe series, Primal Prime later combines with Apeling into the robot Sentinel Maximus in an attempt to stop Cryotek.
