Its been years since Cybertron fell and all of the Autobots went to live on Earth leaving behind their home world for a new one and Optimus had been missing the old days when he was just a pupil to Prima Prime who was one Prime that had picked Optimus up off the streets of Cybertron and made Optimus his student even though Prima was very busy and couldn't always be there to teach Optimus Prima did try and was like a father to Optimus and even called Optimus his little lamb bot when Optimus was young and Prima is the Prime of light and Prima is the Light for all of Cybertron meaning if something bad happened to Prima then darkness will threaten Cybertron since Prima's Matrix holds the life blood of Cybertron which is gold Energon, the life force of Cybertron until Prima and the other Primes died by Sentanal Primes hands and now Optimus would give anything just to see his old mentor again when Bumblebee come on the comms saying that he had found someone and Optimus and the other Autobots went to Bee's location in an abandoned warehouse and when they got inside Optimus froze at see Prima Prime here on Earth in a stasis pod in stasis when Prima should have been dead and Ratchet rushes over to Prima's stasis pod and scans it

Ratchet: scans the pod in shock By the All Spark my scanners are picking up that Prima is alive!

Optimus: is unable to believe that his mentor that he thought was dead is right in front of him in stasis

Bumblebee: is very confused But shouldn't Prima be dead since Sentinal Prime killed all of the other Primes? (you represent as Prima Prime)
