-G1 Universe-
The Autobots and Decepticons were fighting a battle over an unfinished space bridge. The autobots and decepticons were of equal level and power but the autobots had the day, their victory was inevitable but it would not be the final victory.
Optimus and Megatron were fighting in the space bridge but it wasn't activated, so they continued their battle.
"Die, Optimus Prime!" said Megatron to his truly greatest enemy, Optimus Prime as he swung his energon mace towards the Autobot leader who just as quickly dodged and used his energon axe to hit him.
"You're a rusted model, megatron!" said Optimus "ready for the scrap heap" as he used his free hand to punch megatron who was sent backwards.
Megatron then in a rage aimed his ion cannon at Optimus and fired but Optimus quickly dodged the high speed blast but it hit the Space Bridge however instead of blowing up, it created a dimensional portal into another dimension.
All of a sudden, hundreds of transformers were pulled into a different universe.
-In the Alternate universe-.
All of a sudden Optimus falls onto a knee as he the Matrix had told him about the multiverse and how autobots and decepticons of a different universe had been transported to this one.
"Optimus, what is it?" Ratchet asked his friend and leader, concerned.
"Members of another universe have come to this one!" said the Autobot leader.
