1.I want to get this straight... Unicron exists in the MULtiverse, and can travel freely between UNIverses. Primus, on the other hand, exists in all UNIverses at once, and each one is Primus' body. Is this right?-ANSWERED
2.Before the dawn of time, Order and Chaos existed within an extradimensional entity known as the One. He created twin astral beings to reign over the cosmos: Primus and Unicron. Their nature differed, as Primus's lifeforce was a multiversal singularity; existing across all Transformers realities at oncewhereas Unicron existed in only one dimension at a time but could travel relatively freely between them. Primus was the Lord of Light and Order, and Unicron, the Lord of Darkness and Chaos. They fought for thousands of years, until Primus had no choice but so sacrafice himself to trap himself and his brother inside two giant hollow asteroids. Unicron’s dark essence managed to escape, and so it began searching for a new body. Primus had sensed Unicron escaped, and prepared for their next meeting, creating 13 robots to aid him in his fight. He also sent out his essense to a lab, where a being named Primacron worked. He was a brilliant scientist. But the essence did not go to him, but to his assistant. Primus sent a telepathical message with his essence telling him to find a way to contain it so that Primus’ robots could use it againt Unicron. Without his essence, then, Primus’ body was no longer that, it was just a planey. The assistant put the essence inside two handles, which contained the energy, and placed it in a secret place. Unfortunately for Primus, Unicron had sensed the energy and tracked it down to the lab. Witnessing Primacron’s ability to build amazing technology, Unicron telepathically planted a thought in Primacron’s head: “Build a gigantic robot to wipe out the universe, and remake it in your own image.” So, within time, it had been done. Unicron’s essence immediately took shelter in to robot, possessing it. He swiftly destroyed Primacron’s lab, killing his assistant and badly hurting Primacron. Primus’ essence (The Matrix) escaped the ordeal, and retreated back to Cybertron (Primus’ Prison asteroid). Unicron, in his new body, scanned his former prison asteroid as an alternative mode. Unicron then created an army of twisted beings called the Quintessons to find Primus’ body (Cybertron) and destroy. They did find it, but they didn’t report back to their master. They, instead, enslaved the entire robot population there, removing their sparks. The sparks were able to create a mini alternate dimension for themselves to exist in- the Allspark. The Quintessons found the Matrix, and sealed it away. Then one day, a robot codenamed A3 stumbled upon the Matrix. It showed him Primus’ vision and gave him back his spark…
-Is this a good explanation for G1 toons? Please proofread for me, as I am not very good at it.

If I think of any other q's, I'll post em here.
