Planet X (Cybertron) - Transformers Wiki (2024)

The name or term "Planet X" refers to more than one character or idea. For a list of other meanings, see Planet X (disambiguation).

Once, in the distant past, Planet X was a world to be feared. Existing in a parallel reality, it was home to a race of warriors, thieves, assassins, and techno-marauders, who turned the very planet itself into a colossal weapon that they used to wreak terror and destruction across the face of their universe, obliterating all other worlds and civilizations that stood in their path. This unholy crusade was ultimately Planet X's own undoing, however; when it entered into a war with Gigantion, the Giant Planet, the denizens of Planet X were forced to unleash energies so uncontrollable that they consumed their world, destroying it utterly.

While the planet itself is no more, "Planet X" remains a phrase of fear uttered only in hushed tones, for now, it serves as a codeword that links these survivors, who have become a secret society whose every action is shrouded in mystery, misdirection and deceit. Nobody knows just how many survivors there are out there in the universe, but it can be assured that wherever one of them appears, tragedy will soon follow in the wake of their passing—a fact proven most visibly by the only two known, named survivors, Sideways and Soundwave.

Fiction

Cybertron cartoon

Learning that the energy of their world, and indeed, all life in their universe, was slowly dying out, the inhabitants of Planet X reached out to the fringes of space and time, discovering the planet Gigantion in a neighbouring dimension. Intending to make it their new home, they pulled it through a space warp into their universe and immediately laid siege to it. Unfortunately for Planet X, Gigantion was one of the worlds chosen by the ancient Cybertronians to be a colony planet, complete with a Cyber Planet Key, the energies of which the Gigantion were able to utilize in order to increase both their size and power, and the size of Gigantion itself, in order to fight back.

The war steadily escalated, until Planet X "dropped the big one", and inadvertently destroyed themselves with a weapon they could not control. Challenge

When the Autobots and Decepticons subsequently undertook the quest for the Cyber Planet Keys, Sideways and Soundwave took matters into their own hands, confusing and conspiring with the two factions with the aim of eventually procuring all four keys and using their power to take their vengeance on Gigantion. When the keys were all assembled and Megatron and Starscream began battling for possession of them, Sideways and Soundwave tried making a grab for the keys, but were caught in the reality-rending energies released by the two Decepticons' battle and blasted into another dimension. Showdown As it turned out, this was to be a happy ending for the pair, as they discovered an intact version of their home planet in this other dimension, and set up residence there. Beginning

Planet X was once the remnant body of Unicron, left behind after Megatron absorbed the dark god's spark. In another space or universe, the regenerative functions of the planet went awry and, to supplement the planet, Cybertronian Transformers previously absorbed and incorporated into his own being by Unicron were restored to existence. They, now denizens of Planet X, found Unicron's memories and copied it onto a medium of their own invention, with Soundwave acting as an administrator for this data. Even after the destruction of Planet X, Soundwave continued work in deciphering the data, discovering a universal history of constant conflict and the existence of Primus, Unicron's nemesis, and his Cyber Planet Keys. Finding that both were linked to Gigantion, which caused the destruction of his planet, Soundwave decided to steal the Cyber Planet Keys, bring around the restoration of Planet X to its complete state, and take revenge on Gigantion.

In the end, Soundwave and Sideways found an intact version of Planet X in a parallel world.^[1]

Immediately after Planet X met its end, the surviving scholars of the planet pooled their knowledge in a quest to find a means of revenge against Gigantion. Lore of an ancient, planet-devouring being brought them hope, and they split up across the universe in their search for it. It was Soundwave who would end up succeeding in the millennia-long quest, finding and entering into a bargain with the chaos-bringer, Unicron: one million years of servitude in return for the assured destruction of Gigantion.^[2]

The Planet X of Aurex 802.23 Alpha was originally a peaceful world hailing from Primax 994.0 Gamma. This changed after Jhiaxus and the Cybertronian Empire took over the planet, colonizing and cyberforming it. After the Cybertronian Empire fell, the remnants of its forces, led by Firecrest, fell back to Planet X, cloaking and fortifying it. Due to the constant searching of The Veteran, Planet X and its inhabitants fled their reality entirely and found a small pocket universe which they waged war against, though the inhabitants scorched their reality in favor of being slaves to the Cybertronian Empire. With little energy and life remaining in their current dimension, Planet X again shifted realities. Ask Vector Prime, 2015/06/05

The Planet X that menaced Aurex 105.08 Alpha was the shattered carcass of Unicron from Primax 886.0 Gamma, which had been inadvertently blasted into Tyran 609.08 Kappa by Rodimus Prime and the Matrix. Unicron hung around the Solar System as an unnoticed "Tenth Planet", but the universe's nature as a binary end-state universe prevented him from fully repairing himself. In an attempt to fix this, his comatose self resurrected many of the Transformers he'd eaten. They dubbed their world Planet X, warped over to Primax 290.0 Zeta, and started conquering the place until the local Autobots used Zodiac energy to drive Unicron's presence out. Half of Planet X went with it, ending up in Aurex 105.08 Alpha to battle Gigalonia, while the other half remained as a paradise world. Ask Vector Prime, 2015/06/08

The reality with an intact Planet X which Sideways, Soundwave, and Laserbeak ended up on after being blasted out of Aurex 802.23 Alpha was Aurex 906.29 Alpha. Ask Vector Prime, 2015/08/03

Viron 704.08 Gamma also had a Planet X. The population of this Planet X was united by Unicron, a (seemingly non-singular) conqueror and tyrant who used the power of a Cyber Key to merge his consciousness with his planet and proceeded to try to consume the universe before Omega Prime and Fortress Maximus stopped him. Ask Vector Prime, 2015/07/28

In Viron 102.0 Beta, the Elite Guard blockaded Planet X in the Skeleton Nebula. Ask Vector Prime, 2015/09/22
