megatron by darkzone

The original Megatronus, better known as the Fallen, was one of the original Thirteen Primes created by Primus. Megatronus betrayed his creator by siding with Primus' dark twin, the malevolent planet-eater Unicron. In the final battle between Primus and Unicron, Megatronus fell victim to the same fate as his master, sucked through a black hole into another dimension. However, while Unicron emerged in another universe, the Fallen was not so fortunate, finding himself trapped in the "underspace" between dimensions. Another being addressed simply as Megatron is an apocalyptic figure said to bring about death and destruction through alteration of the time stream. Possible interpretations in the book of him are "Alpha and Omega" and "The Great Dragon".
