Does he born or built already? Or does Optimus been send away hiding by other primes/sentinel beings(people?) when news arrived to Cybertron about the betrayal of the Fallen? Where does he at this time. Let's get imaginative and try to built a background story of this event will ya! I read the defiance and alliance but no story of this.. or do i miss something here.? Maybe Primes mean hope for Cybertron and (people?)sentinel beings of Cybertron hided Optimus so they will have a living prime as rightful ruler. Well, seems like time has forgot who Optimus was until certain artifact been resurrect and related to Optimus being a prime though symbols on his head. And what's your story?..
