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.
I started watching Transformers G1 when I was around 7, incidentally 2007 is the year the Michael Bay Transformers movie came out. Being only 7 at the time I was mindblown by the special effects! They all looked so real to little me! From then on, I HAD to see every Transformer movie when they came out. I know the Bay movies aren't perfect, but they do have a special place in my heart. Optimus has been a very important character in my life. I used to play make-believe with the neighbour kid and we'd argue over who's backyard the Autobots would be sleeping in lol. I used to bring my giant Optimus figure to school with me. (yes, i was that kid lolol) Anyways, being the lonely kid/adult I am, having my Transformers figures around made me feel less alone. Like I had friends. Which is super sad and lame to admit, but it's true.
