The Fallen is a fictional robot supervillain in the Transformers robot superhero franchise. According to Hasbro, he was formerly known as Megatronus, and was a multiversal singularity, meaning that while he exists across the multiverse, there is only one Megatronus. This is no longer the case because of an event called The Shrouding, where all multiversal singularities within the Hasbro-Takara multiversal now exist as separate beings within each universe. As explained in more detail in the appropriate sections below, the Fallen has been given different origin stories in several of the different continuities in which he has appeared. 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. Megatronus was one of the original Thirteen Primes created by Primus and the founder of the Decepticons in many storylines and the catalyst that led Megatron to claim power for himself instead of the greater good. Originally he was depicted as having betrayed his creator by siding with Primus' dark twin, 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. This origin has been altered or revised several times, even to the point that Primus and Unicron are removed entirely, even so, this is because he can jump through time and space, and hop dimensions, like the other Thirteen Primes. Challenge of the GoBots In the 1985 Challenge of the GoBots episode "Search for the Ancient Gobonauts", "the Evil One", is retroactively a version of Megatronus, according to "Ask Vector Prime". He nearly destroyed Gobotron with a device called the Dark Heart, only to wind up under the Nazca Lines on Earth. Centuries later, Cy-Kill goes on a quest to look for the ancient villain. Transformers: Generation 1 continuities Beast Wars Years before the Fallen was introduced in the Generation 1 Dreamwave Productions comic book, Transformers: Beast Wars would introduce a similar character. This character was known simply "Megatron". Both the Generation 1 Megatron and Beast Era Megatron named themselves after this mythological figure. It is unknown if this Megatron named himself after him or if they are the same character, but all that is known about him is
