On the topic of non-MegOP Optimus ships in Prime, I really enjoy how much room there is with basically everyone to address how it's questionable if Optimus even knows he's allowed to want things for himself. Orion was always a duty-fulfiller, and became ensnared in the revolution out of frustration with what he saw as flawed methods to a noble end, not because he necessarily wanted any of the specific outcomes of a successful revolution for himself, and even if you ignore Optimus being a literal tool of Primus, he very much came into existence in service of the goals of the counter-Megatron elements and has been trying to fix the problems someone else has caused ever since. There was never an option where Optimus wasn't just reacting to the actions of the real movers and shakers, it always fell on him to do damage control.
Scenarios where Optimus lives at the end of the war are interesting to me b/c he's had to go for so long, only thinking about other people. His focus has been servile, external, and now he has to figure out what he wants, and if he wants something different from the path of least resistance, of letting others tell him what they want from him. Relationships especially take bravery, they take initiative, they take sincerity and the ability to advocate for yourself -- and there's probably some interesting stories to be told about Optimus drifting in and out of unsatisfying relationships because they're there, because he's so used to thinking about himself in terms of availability to other people.
( Ship nonsense. )
