Blue Planet (GS)
Existing within the previous universe, the oddly familiar water-covered Blue Planet (青の星 Ao no Hoshi) was until very recently the bustling metropolis at the heart of the joint Primus Vanguard/Beast People civilization and the homeworld of the Blue Order. Now it's where people shout exposition at Star Convoy.
There's also a couple different competing apocalypse cults. It's a whole thing.

Generations Selects comic
The Vok of the next universe attacked the Blue Planet as part of their efforts to alter the timeline. Super Megatron comic 3 In response to this, the eponymous leader of the Primus Vanguard made use of his vast power to pluck Optimus Prime and Galvatron from 2011 of the G1 World into orbit around the Blue Planet, gifted Optimus the mysterious Silver Matrix and tasked them with sorting the local pest problem. Optimus used the power to upgrade himself into Star Convoy and made short work of the Novaroids. Star Convoy comic Primus cryptically tasked him with collecting "Star Power" in the Silver Matrix to save 'their collective future". Seacons comic 2
The two were then intercepted by the photon sailer of the twin Seacons. While Galvatron was able to parley safe passage and an upgrade of his own in return for the Unicronian energy within his body, Seacons comic 1, Star Convoy got the stuffing beaten out of him by an Angolmois-juiced King Poseidon all the way down to the surface. Seacons comic 5
Just as it looked like curtains for Star Convoy, King Poseidon was exploded by none other than an upgraded Super Megatron, fresh from crashing the pirates' ship as soon as he got what he wanted. Super Megatron comic 1 Super Megatron greeted his old enemy with a demand for the Silver Matrix that he could gain yet further power. Star naturally declined and a well choreographed scuffle ensued until they reached a nearby city and Megatron threatened to eat (yes, eat) a pair of Beast People. An ashen Star Convoy complied and Super Megatron bonded with the Silver Matrix to become Ultra Megatron!!! Super Megatron comic 2
Just as it looked like curtains for Optimus (again), he was rescued from Ultra Megatron's ultra attack by none other than Blue Big Convoy as the Blue Order rendezvoused with their guests. Blue healed Optimus's wounds as his troops kept Megatron occupied. Just as things were looking up, Blue made the no good very bad decision to parry Ultra Megatron's Silver Matrix attack with his own Blue Matrix, allowing the Silver Matrix to absorb its Blue Star Power and evolve Megatron even further into Ultra Megatron Omega! Super Megatron comic 3
Just as it looked like curtains for Optimus and the Blue Order (yet again), Ultra Megatron Omega was repelled by a blast from Primus as he received his guests in person at last. As his Vanguard prostrated themselves, the god explained to Optimus that this universe was the one that existed before his native one—the destruction of this universe ensured the birth of the next. Megatron Omega attempted an attack while Optimus was distracted by exposition, but was foiled by a revived King Poseidon, newly committed to avenging his fallen crewmates. Seeing that fighting was unavoidable, Optimus powered up to Star Convoy once more.
Elsewhere in the city, Primacron and the Three Wise Ones observed the distant battle. Primacron had a plan: collect all the Star Power into the Silver Matrix, destroy the universe, and create a new one. The one to spark the Zodiac energies of the Big Bang would be the god of the next universe, he believed. Super Megatron comic 4 With the theft of the Blue Matrix, Primus alerted the other colored Orders of the Primus Vanguard to defend their respective Matrices from Megatron Omega, for if he retrieved all seven, all was lost for this universe.
Abruptly, the Blue Order was torn asunder, its members driven to attack each other by the program secretly implanted into them by one of the group's Straxuses. Blue realized the betrayal, and the other Straxus—Director Straxus—mocked him and exclaimed that the previous commander, Brightes, shouldn't have passed him over for Supreme Commander in favor of Blue. Refusing to harm his comrades, Blue fell on his own Matrix Sword, but the amused Straxus simply retrieved the blade and offered his services to Megatron Omega. Megatron departed the Blue Planet in search of more matrices with the Straxuses in tow.
Primus explained to Star Convoy that, while the members of the Blue Order had perished, their sparks would be stored in his Ark and pass on to the next incarnation of the universe, and casually dropped this ritual sacrifice is why he led Galvatron here in the first place. Turtler alerted Star Convoy to a more immediate mystery: the absence of Halfshell from the crashed photon sailer! God Neptune comic 1
Primus was alerted to the revitalized Pirate Seacons' attacks on the remaining Warriors of Lights. Star Convoy recognized one of the Seacons as Halfshell, and Primus explained that he'd been changed by the god-rivaling power of Angolmois Energy, which could allow one to change their or others' form and even resurrect the dead. This revelation was cue for Primacron to barge in and berate Primus for using his creation, bringing it from the future and having it proliferate in this universe. Primacron demanded to know just what Primus, or, rather, the Oracle was planning. God Neptune comic 2 Primus exclaimed that he was out to foil Primacron's plans and called Primitive warriors to him! God Neptune comic 4
Summoned by Primus, the Dinobots arrived. Star Convoy and Grimlock immediately recognized each other, and Grimlock explained that his world was being attacked by Megatron Omega. Confused, Star Convoy pointed out that he was currently fighting God Neptune out in space, but Grimlock clarified: he meant the original Megatron Omega from his time, 2050. Volcanicus comic 1
