Optimus Prime

Optimus Prime is the awe-inspiring leader of the Autobot forces. Selfless and endlessly courageous, he is the complete opposite of his mortal enemy Megatron. Originally a mere civilian known as Orion Pax or Optronix, he was chosen by the Matrix of Leadership to command, the first in a number of heavy burdens he has been forced to bear. Another is his bringing of the Transformers' conflict to Earth. Every casualty, human or Cybertronian weighs heavily on his spark. He does not show this side to his soldiers and never succumbs to despair. The Autobots need a decisive, charismatic leader and that is what he gives them. It was that leadership which turned the tide of the Great War.
