Earth (Tyran)/707.04 Delta

Personality & Character
Unicron is the literal incarnation of Chaos. As stated by himself, Unicron lives to destroy his brother Primus, who embodies order. It has been shown that he holds grudges, as after billions of years his sole wish was to destroy Primus and any primes. Unicron is a bitter and cruel spirit, who never understood the true meaning of good. He is also very single minded, as he had clearly never thought of what he would do if he ever achieved his goal. He is prideful and arrogant, looking down on everyone except Primus. According to the Covenant of Primus he found identity in hate which drove a wedge between himself and Primus.

Background
As the Universe began to form, the only living things (at least in their part of space) were Primus and Unicron on the uninhabited planet Cybertron. The two dueled for the fate of the universe with neither getting an advantage for long. According to Optimus the tide was turned more times than it could be counted. To turn the tide firmly in his favor Primus created the Thirteen to fight with him. With these additional warriors Unicron was defeated and cast out into deep space.

As he drifted and in slumber, space debris began gathering around him due to his gravity field. Eventually he was caught in the third orbit of a sun and became the very core of planet Earth in the Milky Way galaxy. The Covenant of Primus unveils a prophecy that foretold Unicron's awakening on Earth, though the details failed to mention that it was actually referring to Unicron and Earth. On Cybertron, stories were told of Unicron's defeat and he became a feared figure. But over time, as society marched forward, the Cybertronian people dismissed the Chaos Bringer as nothing more than a legend.

Power & Abilities
As a literal god, Unicron is extremely powerful much, like his twin brother Primus. Being Earth's core, he possesses a symbiotic link to the planet and is able to manifest whatever comes to mind on the surface such as stone avatars, tsunamis, earthquakes, and volcanic eruptions.
