The Fallen

The Fallen was a name given to the member of The Thirteen originally known as Megatronus, after he betrayed his brothers in their fight against Unicron.

After Unicron's vanquishing, the Fallen set out into the Universe to find the Essence of Unicron and help restore his dark master to full strength.

He eventually tracked down the weak spirit of Unicron and aided in his recovery and adoption of a new form.

Once of sufficient strength, Unicron gave The Fallen orders to leave him and execute two orders.

One: Return to the original battlefield, now the planet known as Cybertron, and using the forgotten technique of Sacrifica, bring Sparks into this Reality, planting a taint of evil among the populace to upset the peace on the new world, which over time would lead to the society tearing itself apart.

And two: Track down the remaining members of the 13 hidden among the Stars, and destroy them.

The Fallen executed both orders as instructed, killing the last of his original brothers, Prima, in a battle which left The Fallen grievously damaged and close to death. He cried out to Unicron for aid, but Unicron simply laughed, abandoning The Fallen to die.

The shattered form of The Fallen was then stumbled across by a small squad of Cybertronians – Jhiaxus and his troops.
