Although the original Japanese incarnation of Transformers: Cybertron, known as Transformers: Galaxy Force, was produced apart from Armada and Energon, the series, as originally conceived by Hasbro, was as the third part of the trilogy. The English language dub of the series treats it as such. Consequently, inconsistencies arise between Cybertron and the other two series, but have been explained by the Cybertron comic book, available exclusively through the Official Transformers Collectors Club, as the result of fluctuations in the fabric of reality caused by the Unicron-induced black hole.
After the Great War, Optimus Prime disappeared with other legends into the mysterious location on Cybertron dubbed J'nwan, where Optimus himself became the "Authority" who spoke on behalf of the others. Sandstorm, the leader of a rebellion in a 32nd-century firmly under the heel of the tyrannical Shokaract, entered J'nwan to plead with the heroes of Cybertron's past for aid. He hoped to convince them to join the fight against the Predacon warlord. After a mind-crushing journey which left all of his companions dead or deranged, Sandstorm finally found an audience with the Authority and his brethren, but they declined to help, with the Authority stating that their time was past and the war was no longer their war. The Authority then in some way manipulated Sandstorm's trip out of J'nwan such that it was comparatively short and simple. Paradox
Throughout the first two seasons, Optimus Prime has led the Autobots to many victories, such as stopping Megatron from controlling the crystal of power, stopping the Dinobots' rebellion by saving Grimlock, defeating Devastator with his detach arm, helping capture Nightbird, rescuing Blaster and Cosmos from the Decepticons on the Moon with the help of Omega Supreme, and helping save Perceptor and the other Transformers from the cosmic rust disease.

Within G.I. Joe's headquarters, Optimus found Doctor Venom controlling a robotic suit made out of the remains of both Bumblebee and Soundwave. The battle between him and the Joes spilled out into the open and into another battle, where Decepticobra was attacking the United Nations. As more factions joined the brawl, Optimus yanked Bumblebee's components free from Soundwave's body and took to the skies, back to Cybertron. Expelled from the Garden There, he was able to reunite Bumblebee's body with his head. Headmasters
In some continuities, though, it’s our lovable pal Bee who takes the leadership reigns. In the animated series Transformers: Robots in Disguise, with Optimus having died at the end of the previous series, Bumblebee starts off as the Autobot leader, but he’s apprehensive about it. And he even takes the leadership mantle in the live-action film series; taking over for Optimus, who leaves the Autobots behind to head into space to search for the Seed at the end of the last movie, Age of Extinction.
Part of the sixth wave of Custom Kreons, and the first (and only) Robots in Disguise-themed wave, Optimus Prime uses the new 2015 Kreon construction with the hollow waist-peg and "raised" hands.. He comes with a buildable parts rack on which to hang/store his extra pieces. Unlike the previous Custom Kreons, he no longer features a chromed helmet, and comes with an extra clear-plastic helmet, torso, legs, and his arms, plus a chromed Bazooka (originally from the Kre-O Battleship sets), and some kind of a dual pick-axe with a clear red staff.
Late in 2008, this version of Optimus prime was one of four Classics figures repainted into HasbroToyShop.com exclusives (the other three being the Megatron from this set in G1 colors, Grimlock repainted into Overkill, and Mirage repainted into Dragstrip). Unlike those three, it's debatable just how much repainting went into Optimus, but he comes in a snazzy new box.
This gold vacuum metallized (save for his black joints, which they were made out of unpaintable plastic) Protoform Optimus Prime figure was featured as a Lucky Draw giveaway (along side similarly gold vac-metal versions of Voyager class Optimus Prime and Protoform Starscream) in the December 2007 issue of TV Magazine. Released in 2008, only 5 pieces were made, making it one of the rarest Lucky Draw figures; the images at right represent the only known photographs of it.
