Transformers: Dawn of Cybertron

Long ago, so long before Unicron was trap into the container of the Allspark that sealed him away. Everything was so different for everyone. No one knew how much everything started. No one knew who really were Unicron and Primus, at the dawn of life. No one asked such questions to themselves and to the others.

At the beginning, Primus wasn't a being of wisdom and powerful that created the Cybertronian. He was but an immature and shy being and a little coward when danger came who loved his brother Unicron.

Unicron wasn't the chaos bringer and the destructor of planets that wanted to murder his brother Primus. He was but a being with aggressive issue and a loyal and protective brother who would never let Primus be hurt.

How did everything turn so bad? How did they want to destroy each other's? Who did fate and time tear them apart?

Their existence was different from every stories, it was only the path to pain and tragedies.

Prologue: Long ago, we were punish

At the beginning of time, nothing was existing in the Universe; only planets, stars and gaz. There was no life, corresponding to the normal version of existence. One being was present and absent in the existence of this empty Universe; the creator. He was there a few times, without manifesting himself. He eventually decided to start creating the existence in this plane of existence.

A large star appeared near a planet made of metal; a nameless world at that time without any structures. From the star, came out two metal beings, immense and small at the same time. The came out a little confuse. They looked at themselves and they saw their body being solid. Their body were identical, but felt different. It was covered with their blood, one light and blue and the other one dark and purple also known as energon.

"Creator...Were are we?" Asked the one with the light and blue energon. He was unsure about their presence here.

"Primus, you are now in another plane of existence, below the one you were currently living." Said the creator.

"Why?!" Shouted the one with dark and purple energon as if it was unfair.

"Be at peace Unicron, it is not because I'm angry at you two that I sent you there. It is a punishment for the fight you have with the others of your kind." Said the creator. His voice was resonating, calm, but contained reprimands in it. "As punishment, you will now create and administrate this existence."

"But creator! Those fleshy thought we were inferior! They are the one-" Unicron was cut in his fury.

"Do not oppose my will!" Shouted the voice of the Creator. Primus hid behind Unicron for safety. His brother raised his arm in a protective way, covering Primus from anything that could harm him. "They are also punished for their insolence and their fight! You didn't react appropriately to the higher plane of existence. You are immature and not ready to exist there!"

Unicron and Primus looked to their side, putting their servo on their metallic arms.

"You will learn to grow up. You might think I'm unfair. Your have to learn responsibility. Both of you always end up insulting and fighting the others." Said the creator. "If you want to return to the higher plane of existence, you will have first to accomplish your purpose into this world."

"What...What do you want us to do Creator?" Asked Primus nervously over the shoulder plate of his brother.

"Your purpose will be up to you to found out. You will need to guard an important object and used his power wisely. If you succeed, you will be return to the higher plane of existence." Said the creator calmly.

A shining light appeared, the star that made them manifest into this universe grew smaller until it formed a ball of light. It shined with his beautiful color and blinded Unicron, whose power seemed to oppose the ball.

"This is the Allspark, it is a part of myself that I'll left in your hand. You will have to use this power with judgement, if you cannot, you will destroy everything. Failure will cause your permanent destruction." Warned the creator. "This is the last time I will speak to you until your purpose is over. Gods, do you have anything to say, not about the punishment, but to me personally?"

"...Thank you for giving us a second chance...I was sure...You will destroy us." Said Primus. He felt a calm wave from the creator.

"And you Unicron?" Asked the creator.

"...Bite my arf Creator. I hate you." Said Unicron crossing his arms. "You punish Primus too; he was innocent in this fight."

"No. He didn't do anything to stop the fight." Replied the Creator. "He even joined into the fight."

"It was to protect me! I was alone against three of them!" Shouted Unicron.

"You should enter into the fight and he shouldn't join you!" Replied the creator with anger. Primus hid behind his brother again. The creator voice then calmed down. "It is time for me to part away. I will always watch you...Primus...Unicron...I know you will succeed in the task. Remember, you have to guard and protect the Allspark with your spark and used his power for your mission. Unicron, you may hate me...But this punishment is so you can mature and become greater in your spark...I love you both."

They then no longer felt the presence of the Creator. They are now on their own, alone with the Allspark flying around them.

Primus felt the pressure on his crushing him. He didn't know what to do. He was lost into this strange world. He felt a servo on his left shoulder and he turned around. He saw his brother Unicron smiling at him with kindness. His smile was small, but it was only to reassure him.

"What do we do now?" Asked Primus worried.

"I honestly don't know...The only thing he said to us is to use this...Allspark thing." Said Unicron taking the Allspark on his hand.

"By the creator name...We have no home now. We are alone now...No one to guide us like before. Only us." Said Primus. He dropped his helm to the ground and he sobbed a little.

"Don't start leaking now brother." Said Unicron calmly. "You still have me...You big brother. We will figure everything out."

Unicron moved his arms around the body of his brother and hugged him. Primus rested his helm against the chestplate of his brother.

"You're sure?" Asked Primus.

"Yes...Everything will be alright brother." Said Unicron. He looked around him. There was absolutely no life around them. Unicron felt the pressure of loneliness...He was still both furious and glad that Primus was with him. Furious because he was innocent and got punish with him, glad because he wasn't alone. "Everything will be fine."
