Multiversal singularity

Across the multiverse, there are many versions of many beings, each existing independently of each other. They may share similarities, or they may be complete opposites, but each is their own unique individual. However, there are a handful of beings of which there is only one, a single entity without a counterpart in the multiverse. Traditionally of great significance, these beings may exist across multiple universes (even all universes) simultaneously yet remain a single individual (as does Primus) or they may only reside in one universe at a time but have the ability to move from universe to universe at will (as does Unicron).

Multiversal Dynamics

The exact nature of Multiversal singularities was expounded on in Hasbro's July 2009 Q&A session. It is interesting and complex enough to merit reproducing in full:

"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."

Fiction

Unicron has the ability to travel through space and to cross dimensions. He is dedicated to universal domination and he doesn't care what he has to destroy to achieve that. Unicron's Titanium Series toy bio

Unicron has integrated quantum computers which provide him with an ever-updating map of the Multiverse. Hasbro Transformers Collectors' Club issue 10

Unicron travels between the dimensions, seeking a universe with abundant energy for him to feed. When he finds one, he proceeds to devour it completely. Unicron's Universe Armada Series toy bio

According to the Transcendent Technomorphs' records, Unicron has thus far devoured approximately 22.56% of known universes. Withered Hope

Notes

Depictions of these characters as multiversal singularities has not been consistent, especially in fiction that predates the establishment of the Transformers Multiverse.

• In the Generation 1 cartoon, Unicron was part of a series of ever more powerful creations of the hyper-intelligent alien Primacron. After Unicron was destroyed, Primacron decided to try again and created Tornedron. Call of the Primitives

• In the Marvel comics, Unicron devoured the entire universe and then slept, contented that nothing existed. He did not move on to the next universe. The Void! Much later, after the universe was recreated, Unicron sent Hook, Line, and Sinker to pluck an alternate future version of Galvatron into his own reality. Hook claimed the alternate future Unicron was a "different Unicron". Rhythms of Darkness! and Unicron stated that the alternate future Unicron was a Unicron he may or may not become. Eye of the Storm

• In the G.I. Joe vs. the Transformers continuity, Unicron is believed to be an alien banished from his home world. G.I. Joe vs. the Transformers: Black Horizon
