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.
On the battlefield, there are few who rival Optimus Prime's prowess. He is easily the strongest of any Autobot his size, and his ion blaster and energon-axe are deadly weapons. He would sacrifice his life to protect his fellow Autobots or those under their care and does so on a regular basis. His compassion for other sentient beings is his only real weakness, and one the Decepticons have taken advantage of time and again... though it's also the source of his strength!
Angry Birds Transformers comic Edit
Optimus and his Autobots were aboard the Ark, on the run from the Decepticons. With him, Optimus had what Megatron was forever seeking; the AllSpark! With the ship taking heavy damage from the Autobots' pursuers, Optimus ordered Jazz to take them into an emergency quantum jump. Jazz informed Prime that the jump would take longer to initiate than the time the Decepticons would need to board their vessel. As such, Optimus entrusted the AllSpark to Bumblebee while he and the rest of the bridge crew steeled themselves to hold off their enemies. Thanks to Starscream breaking rank in the Decepticons' formation, Optimus was able to hold back Megatron, and with Heatwave's help, repel them from the ship just as it initiated the quantum jump. However, at that moment the AllSpark tumbled off-ship, falling into the quantum tunnel and seemingly being lost for good...
Optimus led the search for the AllSpark through space, but he and his troops were unable to locate the artifact. Though the search seemed hopeless, Optimus assured the others that they would not give up until Cybertron's last hope for survival was found... At that moment, a strange green pig crashed through one of the ship's windows, with the AllSpark in tow. Optimus stared in bewilderment at the strange creature as it asked for a ride back home.
