A/N: So, this is gonna be my second story on this site. After watching The Last Knight in theaters, I felt disappointed. It wasn't what I was expecting. So much more could have been done. There was barely any Prime in the movie, and not enough of his rouge streak in it. So, I decided to start a story based on it, but with more details and more explanations. Oh, and better fights. More fights. Less humans. I want to try to do my best to make a story of what The Last Knight should have been.

Also, warning, major spoilers for the movie.

So, read on. Leave a review/follow/favorite if you enjoyed!

England—Dark Ages

The sound of battle echoed through the surrounding land. Steel upon steel. Wood against wood. Flames burned as men were cut down in waves. Blood soaked the ground. Brave knights fought to push back a barbaric threat… but they were losing.

"Where is the bloody wizard?" A dark-skinned knight asked from his place upon his horse. The worry for the fate of his people was ever apparent in his voice. "Without his help, the battle is surely lost."

A knight to his left looked over to him. The man radiated power, evident even in his armor. For he was a king. One that would become a legend.

"Do not worry, Lancelot," Arthur assured his friend and fellow knight of the Round Table. He looked back out to the carnage that was taking place below. "Merlin will be here soon."

Another knight did not think so as he scoffed at the statement. "That drunkard? Ha! He's no wizard. We'll get no help from him." He too looked at the carnage below. "We need to retreat. The battle is lost. Let us live to fight another day."

"No!" Arthur yelled, his authority resonating through the air as he dismounted his horse and drew his sword. In one swift motion, the legendary king of Camelot drove his blade into the dirt. "Without sacrifice, there can be no victory. Merlin will be here."

Even as Arthur said the words, he did not believe them as he looked upon the battlefield. Scores of men, men who pledged themselves to him, died. The king did not believe they could win in their current state. Merlin was their only hope now, but if they were to lose this fight, Arthur would not run and hide.

"Knights!" He called, raising his sword to the sky. Another wave of attackers were descending on his men below. As he climbed on to his horse, "With me! For freedom! For Camelot!"

"For Camelot!" His knights bellowed back.

"Onward!"

Arthur led his knight down the muddy hill, hooves pounding on the ground as the sound of battle grew stronger. Each knight tightened their grips on their swords the closer they got. Corpses, swords, broken wagons increased in frequency the more they pushed down into what could potentially be their end.

They met the opposition with determined ferocity. Swords sliced through men, pierced flesh, and brought enemies down. Arthur jumped from his horse, engaging his foes on level ground. Screams and shout echoed all around the king now. Until he hear something that did not sound like that of man. Whatever it was was loud and caught the attention of everyone on the battlefield. When Arthur located the approaching source, he marveled.

A dragon, an actual dragon, was swooping down towards the enemy lines. The beast slammed into the ground and took several foes with it. It then began decimating Arthur's opponents. Fire, tail, and claws tore through them with such ease that is was terrifying. And when the enemy began to flee, Arthur couldn't help but raise his sword into the air and let out a victory cry. It was quickly infectious among his knights.

…

"Merlin," Arthur said as he approached the bearded wizard. "On behalf of Camelot and all under its flag, I want to personally thank you. You saved the kingdom. You are in our debt."

The old wizard shook his head. "Oh no, my friend, you shouldn't be thanking me. You should be thanking them." He pointed with his metal staff at the metal dragon that sat off to the side. "It's alright. You can show them who you are."

To say Arthur was shocked at what happened next would be an understatement. The dragon's body began to shift and change. Metal scraping on metal. Then, it started to break apart. Each part shifted as well until twelve towering titans made of metal stood before them. Each of them resembled a knight.

Merlin smiled. "My king, allow me to introduce my friends: the Knights of Cybertron."

Arthur's jaw was hung low. "They are not of this world, are they?"

"No, they are not."

1600 years later—Present Day

It has been said that some mysteries of the universe were never meant to be solved. But who were are and why we exist are not among those mysteries. Some brave souls have ventured to distance places in search of their purpose… even to the black void of space.

In that black, quiet void, one soul floats in a seemingly random direction while on its quest to find its purpose in the universe. Coming from it was a static-filled message played on a loop

"I am Opt… Prime, and this message is to my Cre… tors. Leave pla… Earth alone, because I'm… for you."

Optimus Prime had left his friends to search for those who made him and to demand answers. Now he floats through the stars in a powered down state. Three years in space had made him weaker. To preserve energy for the eventual confrontation with his Creators, Prime entered into a stasis lock. All the Knight could do now was wait until he made contact… however long that may be.

3 Years Prior—Earth

Galvatron marched through the sands of the Mumbai Desert. He was disgusted at his form. A human made form. What he would not do to be returned to his former glory, to become Megatron again. But Prime had to take that away. His own brother by choice. Each and every time.

The reincarnated Decepticon leader snarled at that thought. All his plans would fall through at the very end. He needed something to ensure victory no matter what. But at this point, as long as he could rid the universe of this dust ball he now walked on and return to a revitalized Cybertron, he would be content.

Suddenly, Galvatron caught a glint from a massive sand dune. Metal poking through the surface. Seeing as all he had to do was walk this pathetic planet, he went to investigate.

Approaching the object, he dusted it off. What he discovered was a large and jagged end to… something. The Decepticon surmised that perhaps it was the nose of a ship. A Cybertronian ship. But he knew of nothing on Earth that was like this. It was not one of his scouts he sent long ago. So what was it?

To his surprise, the ground beneath him collapsed. Galvatron found himself falling down a tunnel that was barely large enough to fit him. It was nearly a whole minute before the tunnel ended and he was sent falling forty feet to solid surface below. He slammed into a metal ground with a groan.

Standing up, he looked around. "By the Pit… what is this place?" What he saw was the inside of a curved structure. A massive structure. A black metal that resonated… darkness and death and evil made up everything around him in a spider-web of beams criss-crossing this way and that way. Even he did not like the feel of this place.

A platform in the center of that floor, near where Galvatron landed, began to shift and transform. Galvatron leveled his weapon at it. He observed with caution as a form started to rise. After it fully stood, a Cybertronian double the height of his own looked down upon him. His jagged armor made him look frightening. Pointed shoulders, feet, claws, and horns on the top of his head made the individual look to what humans may call "the Devil".

"Who are you?" Galvatron demanded, powering up his weapon as a clear threat.

The individual merely tilted its head in amusement. And when he spoke, his rumbling voice made the air vibrate. "You should not speak to your infinite betters, Galvatron." He threw his name out like an insult.

Galvatron scowled. "How do you know who I am?" Not many did at present. He recently came came back to life, after all.

"I know a great many things, for I am older than most stars in the universe. A better question would be this: do you know who I am?"

"No," Galvatron answered bluntly.

The individual sneered. "Then I suppose I should educate the lesser beings. I am Unicron."

Galvatron subconsciously took a step back. "Unicron, the Chaos Bringer? Impossible!"

"I decide what is and isn't possible! I am Unicron, and I have a proposal for you."

Galvatron didn't answer to that immediately. He was trying to wrap his mind around the idea that he was speaking to Unicron on Earth. It couldn't be possible. The Chaos Bringer was defeated eons ago, his carcass thrown into a star. Finally, Galvatron spoke.

"What kind of… proposal?"

Unicron smirked. "I know what you want. You want your former glory and home back. You want to be Megatron again, not some ghost possessing a machine made by parasites." The ancient titan began pacing around the Decepticon leader. "You want Cybertron back. As you know, the inhabitants of that planet never were my allies, but I am willing to give both back to you and leave Cybertron alone if you help me."

"And what would Unicron need that would require my help?"

"What you see before you is only a drone. A small avatar of what I could be. My true form is locked in stasis, surrounded by the dirt they call Earth. I cannot go and accomplish the tasks necessary to free myself from this prison. I need a… heralds. Be my herald, Megatron."

Galvatron weighed his options… and they were all in his favor. He regains his former glory and home, and Earth…

"What will happen to Earth?"

"Ripped from the inside, out, hopefully."

Galvatron liked the proposal. The thought that he could become his older self and have Earth eviscerated was a grand one. "I accept. I will be your herald."

"You haven't even heard my terms."

"I can reclaim my former self and my homeworld. Nothing you set before me will be out of reach from my grasp after that is done."

"That is pleasing to hear. But my tasks are simple: bring me the Autobot Matrix of Leadership and the Staff of Quintessa."

That made Galvatron blink. "Quintessa? The builder?"

"The Deceiver. Her Staff is the major component to free me and giving life back to your planet."

"And the Matrix; Optimus Prime has it, and he has left Earth in search of his Creators."

Unicron grinned. "Perfect. Time of waiting would be no trifle. I would wait an eternity longer if needed. Knowing Quintessa, she would want to do things quickly as possible. When Prime returns, he'll lead us to the Staff and the Matrix at once."

Galvatron grinned as well. "And I get to rid myself of Optimus. It's almost too perfect. Now, give me back my lost glory."

Unicron nodded. He raised his hands and tendrils of purple lightning shoot out and collide with Galvatron. The Decepticon leader fell onto one knee as he shouted out in pain. His body spasmed as pieces of metal lifted up from the ground and circled around him. Unicron took another step forward, intensifying the lightning coursing through Galvatron. It went on for ten more minutes. In that time, most of Galvatron's body was replaced and reformatted. He was completely changed. When it was done, Unicron ceased the lightning and stood back.

"Rise... Megatron."

With his body still smoldering, the newly rebuild Megatron rose to his feet. His new form resembled that of a barbaric gladiator. Fusion cannon on his right arm. Large bladed melee weapon attached to his back. The right side of his face held a red coloration, easily distinguishable from the rest of his body. A mark Unicron gave to indicate him as his herald… his servant.

"Go now, Megatron. Wait for Prime's return to this planet. Build up a force until then."

Megatron bowed. "I will not fail you." The Decepticon leader transformed, a Cybertronian jet mode, and soared through the tunnel he fell down.

As Megatron left, Unicron commented, "I would hope so… your life depends on it."

Above the ground soaring through the skies, the newly reborn Megatron sent out a simple message across the globe.

"Decepticons! I have returned!" The message contained a packet of coordinates of where the Decepticon leader planned to set up a base of operations.
