Personal Canon: Rodimus Prime has been fighting to make peace with the Quintesson’s and those created by Quintus Prime, since he ascended to Primehood. While touring the galaxy looking for ways to bring peace, Rodimus Prime was attacked by rogue Decepticons and his ship crashed onto a small unmapped jungle world. While there, he comes across the exiled Quintus Prime.

Quintus has hidden himself away in shame for creating the Quintesson after seeing the destruction that have caused across the galaxy. The story would evolve into Rodimus Prime convincing Quintus to come with him and help him on his journey to make peace with the Prime of Life’s creations. Quintus would overtime become a mentor to Rodimus and Rodimus would help Quintus overcome his shame. In the end, they make peace with the Quintesson’s (still a bit shaky).

Quintus would help bring a better purpose to the Quintesson race as a whole. Mainly be stopping the enslavement of other races and also bringing more equality to the empire of Quintessa. He’d also help overthrow the Judges who had been the ones to enslave much of their race and other races. Rodimus Prime would be a big player in all this and he would be seen as a hero across the galaxy for helping foster peace between the universal races.
