Universal stream

"Hey, let's call this new stream 'Phartz'."
"Heh heh. Cool."

A universal stream is the designator used by the TransTech to describe a single universe/dimension/reality within the Multiverse. The TransTech have catalogued 15,962,782 universal streams (1,176,325 of which have "come to termination"), grouping related universes into what are known as universal clusters and devising a classification system used to give each individual stream an alphanumeric designation.

Universal clusters

There are six "main" universal clusters:

• Primax—the Generation 1 continuity family. Points of commonality between universal streams in this cluster involve the forces of Optimus Prime and Megatron battling over the resources of Earth. It also also includes the Beast Era, a possible future which both factions will evolve into the small and semi-organic Maximals and Predacons.
• Viron—the 2001 Robots in Disguise franchise continuity family, a small cluster in which Optimus Prime's Autobots combat Megatron's Predacons.
• Aurex—the Unicron Trilogy continuity family, containing universes that mostly involve the Autobots and Decepticons struggling over such power items as Mini-Cons and Cyber Planet Keys.
• Tyran—the live-action movie continuity family, a violent cluster in which the search for the lost AllSpark brings the Autobots and Decepticons to Earth, and humanity becomes heavily involved in the conflict.
• Malgus—the Animated continuity family, a cluster in which the war has ended and Cybertron is at peace, and Optimus Prime's Autobots are superheroes on a near-future version of Earth.
• Uniend—the Aligned continuity family, a universal conglomeration of aspects from all across the rest of the multiverse, previously separate from the rest of the multiverse until its quantum membrane was recently punctured by the Dark Spark.

Other minor clusters include:

• Fornax—the Kre-O continuity family, home to modular brick-built Transformers.
• Iocus—a cluster essentially made up of overlapping aspects of other clusters, it is home to forgettable side-merchandise like Hero Mashers, Bot Shots, Construct-Bots, Battle Masters and Attacktix, populated by 'bots functionally indistinct from their counterparts elsewhere in the multiverse, giving the outward appearance of worlds in which characters from different universes exist side-by-side.
• Nexus—the technologically advanced cluster where the TransTech world of Axiom Nexus resides.
• Quadwal—the "real world", in which Transformers manifest exist primarily as toys.
• Yayayarst—the Go-Bots continuity family, home to the GoBots of Botropolis

Clusters in the farthest reaches of the multiverse only tenuously connected to the Transformers include:

• Cymond—the continuity family of various TakaraTomy non-Transformers franchises, right on the border between the Multiverse and the wider Megaverse.
• Gargent—the GoBots continuity family, home to the Guardians and Renegades of Gobotron.
• Lukas—the Star Wars Transformers continuity family.
• Rovio—the Angry Birds Transformers continuity family.
• Xobitor—the Robotix continuity family, home to the Protectons and Terrakors of Skalorr.

Deciphering the terminology

Basically, you could classify this as a universe, Tyran 1208.04 Lambda cos it's a movie cover from 4th December 2008.

Someone will do it too.

For further information, see: List of universal streams

Each universal stream's name consists of three parts, beginning with the continuity family of origin, a number that indicates the "real world" date of creation, and a Greek letter that denotes the form of media. Supplied by writers Greg Sepelak, Trent Troop, and Jim Sorenson, the list of Greek letters and the media to which they refer are:

• Alpha—animated series
• Beta—tech spec/toy/pack-in comic only ("box")
• Gamma—comic book series
• Delta—motion picture/live action
• Epsilon—club/convention fiction
• Zeta—text stories, storybooks, and other prose works (printed)
• Eta—radio/audiocentric universes, books on tape
• Theta—live performance/spoken word
• Iota—Internet-only information (not involved with club/convention)
• Kappa—games (video and otherwise)
• Lambda—covers, still images, and advertisements (there's so many Lambdas these days that Vector Prime stopped keeping track Ask Vector Prime)

So, for example, Primax 984.17 Alpha refers to the continuity of the original Generation 1 cartoon, with "Primax" referring to the Generation 1 continuity family, "984.17" indicating the first episode's airdate of September 17, 1984, and "Alpha" denoting an animated series. Using this information, we could, in theory, determine the names of yet-unnamed universes on our own—for example, the Galaxy Force manga would be designated "Aurex 105.15 Gamma".

How many streams?

The size of the multiverse is vast and unknown. While the TransTech have records of just shy of sixteen million universes, there are certainly many more. When the Autobots of universal stream Aurex 402.0 Gamma began scanning alternate realities when their Optimus Prime became lost in the multiverse, they worked through 75,890,007 realities in addition to their own before locating him. Worlds Collide, Part 4 of 4 Dimensional traveller Bug Bite from Gargent 984.08 Alpha, meanwhile, has claimed that there are over fifteen quadrillion concurrent realities, Games of Deception though it seems likely this figure includes the entire Omniverse.

Major streams

Well over a hundred streams have been named, over half of which are Primax realities. The most influential realities, to date, have been:

• Primax 984.0 Gamma—the U.S. Marvel The Transformers comic.
• Primax 984.17 Alpha—The Transformers cartoon.
• Primax 496.22 Alpha—the Beast Wars/Beast Machines cartoon.
• Viron 901.8 Alpha—the 2001 Robots in Disguise cartoon.
• Aurex 802.23 Alpha—the Armada/Energon/Cybertron cartoon continuity.
• Primax 1005.19 Gamma—the IDW Generation 1 comics.
• Tyran 707.04 Delta—the Transformers film franchise.
• Malgus 1207.26 Alpha—the Animated cartoon continuity.
• Uniend 911.05 Alpha—the Prime/Rescue Bots/Robots in Disguise cartoon continuity.
