Ok so I was rewatching the movie Home from Dreamworks and I got an idea from it
Basically Bumblebee has the role of the character Oh, he's from another world that has been fleeing from an enemy for a long time. The enemy being Knockout and other decepticons, Starscream leading them.
Optimus, aka Orion Prax, has the role of Gratuity " Tip " Tucci, him and Megatron being transformers from Cybertron who had moved to Earth.
Optimus is around 17-18 in this AU, figuring out how to live on Earth during the invasion of Bumblebee and the rest of his alien-ish race when he met Bumblebee at one of the gas stations when he went to go look for Megatron
You can guess the rest of the story lol anyways enjoy!
