If anyone's curious about The Fallen in ROTF:



3. Hasbro copy writer Forest Lee stated at BotCon 2009 that The Fallen is a multiversal singularity, meaning that there is only one of him across all Transformers stories, and there are no variant or alternate universe versions of him. How is this reconciled with the version of The Fallen from the live-action film? After all, there are umpteen versions and adaptations of the events of the live-action film, from storybooks to comic books to coloring books, all which are different and conflict in various ways. Does The Fallen experience each of these universes in sequence, reappearing in a new universe every time he is defeated in the previous universe? What about the Decepticon campaign happy endings in the Revenge of the Fallen video games, where The Fallen is victorious? Is there an in-house theory on this, and if there is can we hear about it, or should we just assume it all works out somehow and the details aren't important at the moment?


The complex nature of the multiverse demands much from singular creatures like the Fallen, Primus, Unicron, the 13, etc. These beings are of a fundamentally different nature from regular individuals, who are repeated endlessly throughout the infinite variation of creation. They must be designed or evolved to deal with certain situations that would drive lesser beings mad.

First of all, time flows differently from dimension to dimension. By necessity, this makes it possible for creatures like the Fallen to appear to exist in two places at the same time. Second, whole new universes are spawned every moment by the resolution of quantum uncertainty. Most of these universes are dead ends that exist for only a few seconds or minutes at most, and encompass only a few critical moments. Therefore, at certain critical junctures, the Fallen becomes a quantum event, experiencing two or more possible outcomes at once, until one of those outcomes proves to be a dead end and collapses. The Fallen then reverts back to the "real" universe. Every story has dozens or hundreds of endings we never see. But the Fallen sees them.

One of the side effects of the Fallen's quantum nature is that his appearance changes slightly from dimension to dimension, based on the expectations of others, and the unique history he has (or has not) established in a particular dimension. He is also bound by the "rules" (gravity, magnetism, etc.) of any dimension in which appears – many of which rules he may have actually helped shape when the multiverse was young. So if time flows backwards in a certain dimension, he is bound to live and experience – forgetting as he goes along – everything backwards.

Smart and savvy dimensional travelers spend time in reverse timescale dimensions, slow-time dimensions, or dimensions in which time does not move at all. This ensures that even if they are "killed," they continue to exist. As you can see, the idea of sequential experience as you and I understand it is pretty meaningless to guys like the Fallen. He does experience all these things, but his mind operates on a higher order so all of this stuff totally makes sense to him.
