Primax 984.17 Alpha

They don't get much bigger than this.

Primax 984.17 Alpha, aka OG001 Spacetime (ＯＧ００１時空), is a pretty big deal as universal streams go. The Spacetime Police of Cloud World reckon it to be the origin point of the entire Transformers brand Multiverse, while the Transcendent Technomorphs consider it to be one of its nine most prominent Transformers media pillar realities.

Fiction

The Transformers cartoon

A Quintesson ship inadvertently left the normal universe through a black hole and entered into the negative universe. The party of kidnap victims on board were unhurt, but found that the color spectrum was shifted in that strange place. They were able to find their way back to the normal universe through the black hole (which was a white hole in the negative universe). The Killing Jar

Vector Prime considered Optimus Prime opening the Matrix of Leadership on a Hate Plague-infected Galvatron, Cyclonus, and Scourge to be a highlight in his career as guardian of space and time. Vector Prime: In the Beginning

Ask Vector Prime

Vector Prime declared G.I. Joe: A Real American Hero, Jem and the Holograms, Inhumanoids, and C.O.P.S. canon for Primax 984.17 Alpha. Ask Vector Prime, The AllSpark Almanac II He also noted that the non-singularity Unicron of this universe would not be able to defeat Darth Vader's Death Star mech from Lukas 577.25 Beta in battle.

A group of G.I. Joes from Primax 984.17 Alpha briefly visited Primax 1185.04 Alpha before finding their way back home. Ask Vector Prime, 2015/06/13 Between 1986 and 2005, several non-Transformer related events curiously similar to Quadwal events taking place during that period happened. Ask Vector Prime, 2015/08/26

According to Vector Prime, this stream is one of several that is particularly prone to brief temporal anomalies, caused by events such as the Decepticons' activities involving Dinobot Island, Unicron's destruction, the Quintessons' Time Window, and overuse of the Eurythmic Harmony (known to be a particularly potent cause).

Primax 984.17 Alpha is one of the nine known "pillar" realities, with numerous branching points and a high amount of quantum echos. Following the descent of the Shroud, the TransTechs dispatched an agent to the point in Nexus 208.0 Epsilon where the universal walls were thinnest with Primax 984.17 Alpha; the agent was assigned to monitor the foundational reality.

Cloud

The Autobots of Cloud World, defenders of the Spacetime World, knew the "OG World" as the first world created, with "OG001 Spacetime" as the beginning of all events in the multiverse; Transformers from all across the multiverse resembled their counterparts in the OG World. Leap OG001 was similar to the almost as foundational 01-OG Spacetime. Fury

When the Megatron of Cloud World seized control of the power of SARA, he blasted himself and the Optimus Prime of his universe into OG001; Prime was found by the native Autobots, at which point they were attacked by the native Decepticons, but all three parties soon found themselves forced to team up to take on Cloud World's Megatron. Leap Fortunately, SARA was soon able to reassert control over her stolen power and returned "Cloud Optimus" and "Cloud Megatron" back to their reality. Rampage

Notes

• Primax 984.17 Alpha is the universal stream designation corresponding to the original The Transformers cartoon. Its specifications are taken from the original airdate of "More than Meets the Eye, Part 1".
• Similarly, its spacetime designation uses "OG," the code for the original cartoon, combined with a unique right to left numerical designation, indicating the original English language broadcast.
• It is presumably very similar to Primax 785.06 Alpha and Primax 509.28 Epsilon.
