Dear Vector Prime, if Rung is Primus in his universe, does that mean that G'nur is the "opposite" mentioned in "Primus: All Good Things"? I don't think so, since he doesn't appear in the Guiding Hand stories, but in that case why does he look like Rung?
You are quite correct that G'nur of the Pious Pools was not one of the Guiding Hand, but equally right that he did resemble Rung. Of course, they never met under those identities, so they never discovered the similarity.
In fact, G'nur never really gave any thought to his body, even though he knew it was not his original one.
The truth of this story involves going back to the dawn of Cybertron, the ignition of the first five Hot Spots, each done by one of the future Guiding Hand. The Pious Pools were lit by Primus, and the tribe that marched out of the Pious Pools took his insignia as their own, seeking to bring light to Cybertron. They took a myriad of forms, but even then there was a tendency for hero worship among them. G'nur reforged his body to look like that of his mentor, something Primus mildly disapproved of but refused to outright condemn. (Later, in another life, Rung would feel some remnant of this disapproval when he examined those bots who chose to reforge themselves to look like Optimus Prime. Not for nothing did he name the condition Primus apotheosis.)
G'nur ended up fighting in the God War, and nearly perished at the hands of Adaptus' knights, separated from Rung by one of the first emerging Sonic Canyons. In the end he clung to life, only to fall victim to the electromagnetic pulse that wiped out all of Cybertron's memories.
G'nur woke up, amnesiac, and sought to explore the world around him. He managed to avoid the various dramatic events that plagued Cybertron, and eventually retired to being a barkeep.
As for Primus, he too woke up amnesiac, and the only things he had to base his identity on were his serial number, and G'nur's dog tags. Unfortunately he never realised he held them upside down.
