Although the Fallen's origins are only suggested in his comic book appearance, they would be fully explained in Dorling Kindersley's Transformers: The Ultimate Guide. One of the original thirteen Transformers created by Primus, the robot who would become the Fallen betrayed his creator by siding with Primus's dark twin, the malevolent planet-eater Unicron. In the final battle between Primus and Unicron, the Fallen 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.

The Fallen made his only appearance in the second volume of Transformers: The War Within - the Dark Ages. Around 6.5 million years ago, a test of the experimental "space bridge" matter-transport system on Cybertron liberated the Fallen from his prison, and he materialized on Cybertron, where he quickly recruited the Chaos Trinity, three mystically-inclined Decepticons - Bludgeon, Mindwipe and Bugly - into his employ. Abducting Transformers that he identified as possessing "genetic potential" within their sparks - Grimlock, Blitzwing, Jetfire and Hot Spot - the Fallen planned to use their energies to awaken Primus from his self-imposed slumber, thereby alerting Unicron to his location, allowing the world-eater to renew hostilities with his old enemy. An attack from combined Autobot and Decepticon forces led by Shockwave and Prowl disrupted his plans, and Primus himself reached out and promptly destroyed the Fallen.
Movie Plot *SPOILERS*
He has the ability to teleport and generate a flaming shock wave upon reappearance. His bio says he stands 42 feet tall. The Fallen arrived on earth thousands of years ago. In the present day, he talks to Megatron and reveals that the Allspark's power is flowing through Sam and that he is the key to finding another source of energon. Once freed, the Fallen arrives in Egypt and commands Megatron to find Sam. Eventually, he teleports to Sam and takes the Matrix from him and teleports to the Star Harvester. Devastator uses his turbine mouth to suck away the bricks of the pyramid, revealing the Star Harvester so The Fallen can power it up. Just as he powers the machine up, he is defeated by Optimus Prime.
