Dead Universe

The Dead Universe is an alternate universe from the IDW portion of the Generation 1 continuity family

More like DRED universe, mirite???

The Dead Universe is a mysterious and malevolent realm, a universe that lurks on the far side of all living worlds. This lifeless plane is home only to the vast, undead intelligence known only as D-Void, which preys upon those of the living universe, intent on using them as pawns to expand the borders of the Dead Universe, giving it new life to feed upon.

Various points of access to the Dead Universe exist, with regions of notable death and decay apparently serving as prime loci for the creation of portals between the worlds. Those who cross over from the living universe to the dead are said to become dead themselves, in both body and mind, left unable to survive outside the Dead Universe for more than short periods of time. A characteristic shared by these victims is the presence of an interdimensional link within their bodies that straddles the living and dead universes.

Fiction

IDW Generation 1 continuity

Had nature taken its course, the Dead Universe would likely have been just another one of the many realities that exist within the multiverse. Its fate, however, was forever altered when the Decepticon scientist Shockwave, based in the year 2014, used a time machine to reach back through history to the moment time began in the Dead Universe, whereupon he siphoned off its life energy from the very instant of its creation in order to fuel a grand scheme he was in the process of carrying out. The result was a stillborn universe, birthed into a state of perpetual un-life. The Becoming The Dead Universe would soon receive visitors: zombies created by an infestation from yet another universe and led by Britt. To prevent the infestation from reaching a living Cybertron in his relative past, Kup in 2011 hijacked Britt's transportation gate to teleport all of the undead nearby—Kup himself included—to the beginning of the Dead Universe, where they would find naught to feed on. The Transformers: Infestation #2

The only known native entity to reside within the Dead Universe was D-Void, which was one with the Dead Universe, and sought to expand its borders to consume the living universe. Using an aspect of itself known as the Heart of Darkness, D-Void sought out catspaws within the living universe; Nova Prime felt its pull through his Matrix of Leadership, and so embarked with the crew of the original Ark to follow the sensation back to its source. When the Ark traced it to a cosmic anomaly within the Benzuli Expanse, crewmember Galvatron steered the vessel into the anomaly, transporting them to the mysterious dimension. Spotlight: Galvatron Dark Dawn The crew were rendered undead upon entry, and Nova Prime came into possession of the Heart of Darkness, renaming himself "Nemesis Prime". Devastation #3

The Boyzone reunion tour just got more interesting.

The Ark crew remained trapped in the Dead Universe for millions of years until a permanent gateway was opened between the universes on the planet Gorlam Prime, when the second of Shockwave's Regenesis ores struck the world and decayed an underground chamber, enabling a portal to form there. Homecoming In time, they also learned to use the Benzuli Expanse anomaly to travel back and forth between the worlds, and with access back to their universe of origin now at their fingertips, Nemesis Prime initiated a plan to cause the "Expansion", merging the living and dead universes into one ordered whole that he would rule. Though not explicitly stated, this merge was almost certainly the bidding of D-Void, which Prime was unaware he was following.

Prime's chief scientist Jhiaxus oversaw the facets of the Expansion from a staging base on Gorlam Prime. Devices known as "Nega-Cores" were installed on Corata-Vaz, Rotan and the fourth moon of Bhul, which would accelerate the steady growth of the Benzuli Expanse anomaly, causing the living universe to be subsumed into the dead. Fortunately, the Autobots were able to occupy the guardians assigned to protect the Nega-Cores long enough for the cores to be removed and dumped into the Dead Universe itself by a team protected from its death-inducing effects by Pretender shells. With the cores' detonation, the Benzuli Expanse anomaly collapsed, sealing off the Dead Universe. Simultaneously, Galvatron betrayed Nemesis Prime, slaying him and stealing the Heart of Darkness but was then cast into an energy reservoir by Optimus Prime. Revelation

Saved from destruction by the power of the Heart of Darkness, Galvatron emerged from the reservoir years later and travelled to Gorlam Prime, where he discovered that the portal there had been reactivated. Learning that the entire population of the planet had recently been lured through the portal by a mysterious force, Galvatron entered it himself, returning to the Dead Universe, where he watched as the Gorlamians were consumed by D-Void, the existence of which was revealed to him at last. Escaping its clutches, Galvatron returned to the living universe, destroyed the portal, and set about forming an army in preparation to defend against D-Void's coming, believing that the Heart of Darkness had chosen him to stop it. Heart of Darkness

Told by the Heart that D-Void would be able to emerge through Cybertron since it was a dead world, Galvatron attempted to stop it by feeding the Heart to Vector Sigma, the mega-computer at the planet's core. What he did not realize, however, was that he was enacting D-Void's will, and that feeding the Heart to Vector Sigma would transform the planet into the portal that would allow it to fuse the living and death universes, consuming all life. Fortunately, Optimus Prime was able to open the Matrix and close the portal, sealing off the last known opening to the Dead Universe. Chaos

Galvatron and Nova Prime were reborn within the Dead Universe following their deaths in the living universe. After using Ore-14 and Ore-2 to create an undead Necrotitan, Shockwave and Jhiaxus used the space bridge at its heart to make contact with Galvatron and Nova Prime within the Dead Universe and plan their return to Cybertron. Black Metal Though establishing the link burned out the titan's space bridge, Shockwave simply captured Megatron and used the space bridge within his body to open a portal for the pair to emerge from. Into the Abyss

At the same time, the destruction of Gorlam Prime at the hands of Jhiaxus created a one-way portal into the Dead Universe. Orion Pax led a team inside to investigate, only to find that the Universe was shrinking. Black Metal After Ironhide pushed Nova Prime back through the portal in Megatron's body, Nova confronted Orion Pax's team and demonstrated that the collapsing universe was giving him increasing control over its reality, No Exit before revealing that he had captured Kup and was trying to use his connection to the living universe to create a space bridge from the ancient Transformer's body. The Dead Are Not Enough

Orion Pax destroyed Nova Prime, Finis Temporis and as he and his team escaped with the aid of the Autobot scientist Brainstorm the Dead Universe finally collapsed and destroyed itself. ...And the Damage Done

Ask Vector Prime

When asked if the Dead Universe had its own universal stream designation, Vector Prime explained that it is a "pocket universe" for another reality, and as such does not warrant its own designation. Ask Vector Prime
