On the planet of Cybertron, the Ark was being filled with what ever remained of the Autobot Resistance. The planet was being evacuated.
Optimus Prime, Megatron, Arcee, Grimlock & Swoop were standing their ground on the bridge to Iacon. Quintessa and her army of undead Cybertronians, were chasing the Autobots to their ship. Optimus and his team did their best to fight them off; even though Prime lost his axe, he would still fight for his planet.
While they fought, Ratchet was trying to get everyone on the ship. He stood by the entrance and made sure all the soldiers, medics, bombers, Ariel Bots and common Cybertronians made it onboard, alive.
"Brother, there's no way to stop her!" Megatron cried.
He was right, Quintessa draws her power from Cybertron, the only way to stop her would be to cut the power supply. That would mean, permanently shutting down the planet's core.
Optimus thought about the situation, "If we shut down the core, we can never return to Cybertron."
Megatron turned to his brother and said, "Ragnarok." the prophesy for seeing the destruction of the planet.
It took his brother saying that to realise what he was getting at, "The prophesy; it was never about stopping Ragnarok, it was about causing Ragnarok."
It was decided, they had to destroy the planet, to defeat Quintessa. Optimus told Megatron to go to the vaults of Iacon, Unicron's crown was there, he had to place it in the Eternal Spark. The leader of the Decepticons transformed into his jet mode and flew back towards the city.
Once he was gone, Optimus lead his team in a charge to take out Quintessa's army. Arcee blasted the undead soldiers, Grimlock smashed his was through the brutes and heavy soldiers, Swoop flew above the ground and blasted the undead with his Subsonic Repeater. Optimus ran straight for the goddess, activating his arm-sword. He swung at her, but she dodged the blow and zapped him with her powers.
"You traitor!" Quintessa cried. "You dare to strike your god?!"
Optimus ignored her words and continued trying to strike her.
===============================================
In the Iacon vaults, Megatron took Unicron's crown to the chamber of the Eternal Spark. However, the Decepticon noticed all the relics on the stands within the vault. One relic in particular caught his eye, the Allspark.
Megatron couldn't fight the temptation and grabbed the cube. He place it in his chest compartment, he thought, 'What's the harm in taking one relic?'
Once he had taken the treasure, he continued with his mission; he found the chamber and the Eternal Spark.
As soon as the crown made contact with the blue flame, Megatron began to chant the words of wisdom, "With the power of the Eternal Spark, you shall live again.
The power consumed the crown, Megatron saw a Cybertronian body forming around it; and then the body started growing, bigger than a Decepticon Titan.
Megatron quickly ran outside and leaped into the air, he transformed back into his jet mode and flew back to the battle. As he flew away, he noticed the tower in the centre of Iacon began to crack open.
=============================================
"I am a god, you cannot kill me, Prime." Quintessa cried as she threw the last prime across the bridge.
Further past the ramp that was allowing the Autobots to escape, was a Predicon, it had take the shape of an giant Earth bear. It was caught in a ruthless battle with one other Avenger, a green, scaly, beast had grabbed the Predicon's tail an was swinging it around like an Olympic shot-put.
"Lizard, how you doing?" Arcee shouted to the green creature.
The Lizard replied by roaring at them and then continued to tear it's enemy apart. The giant beast tried to breath fire on it's attacker, but he was smaller compared to the big robotic predator.
The Predicon did manage to bite the Lizard's tail off, then throw him closer to his team members. The bear got ready to charge again, Lizard got back up, as his tail was growing back. The two monsters charged at each other and began battling again, this time, Lizard was going to have the victory.
The bear may have grabbed Lizard in it's mouth, but then the scaly hero crawled down the creature's throat. Whilst inside, the Predicon could feel it's insides being torn apart by Lizard's claws.
Until finally, the bear fell to the ground. Lizard exploded out of it's inside, holding the creature's spark in his teeth. With on bite down, the spark was crushed is his mouth like a chew-toy.
Meanwhile, Optimus was still getting beaten by Quintessa. He then saw Megatron flying to the ship, that's when he knew the plan had come into motion.
Quintessa stated, "You can't beat me, Prime!"
Optimus got up from the ground and replied, "I know.... but he can."
Prime then pointed to Iacon, Quintessa saw the Cybertronian anti-god rise up from the city's insides. Unicron had returned, stronger than ever. The monstrosity swung his large sword through the air, slashing it into the ground and crushing the planet surface under his giant feet.
Quintessa had to stop him, before he destroyed the source of her power. Whilst she was distracted, the Autobots ran for their ship. The Lizard finished chewing on the Predicon, before running for the Ark himself.
Quintessa blasted Unicron with her powers, but all she got I return, was Unicron stabbing his sword down into the planet. She had the unfortunate fate being under the sword when it went down; her body was destroyed when the large blade pierce the planet's surface. The Autobots took their chance and took off.
===================================================
As the Ark left the planet, the Autobots could see their home being destroyed. Unicron did not destroy the entire planet, however, he did blacken the skies and turn the planet's surface into molten magma. This meant what all the Cybertronians were dreading, Cybertron can never again sustain life.
Optimus and his team looked out the ship's window, they also watched the destruction of their planet.
Grimlock turned to the group and said, "Doesn't look too bad. Maybe we can rebuild the outer shell."
But then Unicron set the whole planet a blaze, it was now a fact. The planet Cybertron was now just another star in the universe. Grimlock saw the new star and stated, "Uh, never mind."
The Ark was now on a direct course for Earth, Optimus knew that was the only planet that would except his kind. Okay, now the war was over.
Ratchet approached his friend and asked, "Optimus Prime, what are your orders?"
Prime turned around and saw the leaders chair in the centre of the bridge, he marched to the ship's thrown and sat down. Optimus looked at the star map, they were heading to Earth, so that was a good sign. He looked out the window from his chair, he remembered all the Autobots that were still out in the universe. He decided to leave them a message.
"Calling all Autobots. Cybertron, our home, can no longer sustain us. We must now find a new home amongst the stars. To anyone who receives this message, I'm sending you the coordinates to a planet called Earth. We must protect the planet, and it's inhabitants; until we can find a new home."
"I am Optimus Prime. And I send this message to any Autobots hiding away in the far corners of space. The war is over; it is time, to come home."
