Cybertron Alliance
- The Cybertron Alliance is a faction from the Japanese portion of the Generation 1 continuity family.
The Cybertron Alliance (セイバートロン連合 Seibātoron Rengō) is an inevitably doomed glorious merging of the Autobot and Decepticon armies under the joint leadership of Optimus Prime and Megatron. Bringing peace once again to the Cybertronian race, the Cybertron Alliance has brought about a new hope for a permanent end to their long war.
Fiction
G-2 story pages and mini-comics

After Optimus Prime and Megatron had been resurrected to battle each other, the two eventually settled on a truce. The new Cybertron Alliance would not only end hostilities between Autobots and Decepticons, but would usher in the Second Generation of the Transformers.
It would not last long. After an incident where Earthlings killed one of his closest friends, Megatron called off the truce in a fit of rage and the G-2 battles began. G-2 Part 3
Notes

- While the Alliance lasted, Autobots and Decepticons both wore a previously unseen symbol that combined elements of their individual sigils. The symbol bears a heavy resemblance to the proto-faction insignia discovered by Shockwave in the Generation 1 Dreamwave comic.
