At the dawn of time, he was Megatronus, one of a brotherhood of vastly powerful beings dedicated to the well-being of their world. But The Fallen would gain his current moniker by turning against his brother Primes and his purpose to pursue his own ends, also earning the moniker "the first Decepticon" in the process.

These cauldron-like forces purged him of what empathy and morality remained; all that remains now is hatred and purest rage.
