Key: G1 cartoon/Japanese retcons | Pre-retcon Marvel/UK | Post-retcon/Unicron Trilogy | IDW Guiding Hand Primus/Aligned Continuity/Modern
The Primus and Unicron from the Marvel Comics have had their origins retconned several times. Once leaders of their own respective pantheons of light and dark gods, they have since been rewritten to have once been halves of a single being. After having been retconned so all Unicrons and Primuses across the multiverse are the same being (multiversal singularities), then it was retconned that some universes don't even have a Primus and some Unicrons are not related to the multiversal abstracts.
The most recent retcon has eliminated multiversal singularities altogether. Making all Unicrons and Primuses individuals unique to each reality.
Their showings and abilities tend to differ based on continuity or the laws of the universe that they appear in. As such this attempts to divide them by timeline and era, though not perfectly possible with Hasbro's ever-changing mythos.
