Unicron

Unicron is an powerful being just waiting to be awakened. Known as the incarnation of Chaos and destruction. Unicron goal is to devour all of creation within the omniverse, starting from one Universe at a time to reach his goal.

Unicron is a force to be respected. Originally been the size of a planet and can shoot eye lasers capable of vaporising asteroids as well as turning into a huge planet-like object he designed for his quest of destruction, being able to destroy celestial bodies.

The only thing that can destroy him is the Matrix of Leadership. Let’s hope he doesn’t wake up.

History:

According to legend, Unicron was created during the very early universe, seeing it as filth he set out to devour the universe but that lead to his brother Primus fighting him to save it which the fight lasted 300 million years.

In a desperate act to save the universe he fused with Unicron body and formed a planet which would become Cybertron, trapping the chaos bringer in a prison made out of his brother.

He eventually learned how to manipulate a certain section of his prison and broke off from Cybertron. Turning it into a new planet body for himself. Before escaping to devour planets. 

In response Primus made the Thirteen primes and sent them to defeat him. Though he tried to defend himself by making the Blentron’s he was defeated and put into a coma by the Matrix of Leadership.

 

This was not the end of him though as he eventually formed the earth core and became the planet earth. Overtime he became myth and only the cybertronians remembered him but it was the same time he was waiting to be reactivated to resume destroying all of creation(starting with the main universe).

Another one of his avatars was fighting Gaea (in another universe) when it was destroyed by Sideways. He later recalled his three minions(Ho"ok, Lyne and Sinker) to be sent to the main universe while he sent Grand-Scourge to kill Sideways[The Brail Paradox]
