The first generation Optimus Prime transforms into a Freightliner FL86 cab over semi truck. Within his chest is a mystic talisman, known as the Autobot Matrix of Leadership or the "Creation Matrix", carried by all Autobot leaders. When Optimus transforms, his tractor cab disconnects to become a sentient robot, and his trailer opens to reveal an ion blaster, forming a combat deck. The combat deck supports a mobile battle-station and command headquarters armed with assorted artillery and beam weapons that fire automatically. The combat deck can also serve as a radio antenna for battlefield communications between the Autobots. The combat deck also included "Roller", a mobile scout buggy meant to scout behind enemy lines. When Roller is deployed, Optimus can see and hear what Roller sees and hears. Injury to one component is felt by each of the others. If the combat deck or Roller were to be destroyed, Prime could survive. However, despite the slight degree of autonomy they possess, the combat deck and Roller would not be able to survive without Optimus.
