A 12 issue series, the series expanded the original G1 mythos from the small War on Earth and Cybertron to enclose the whole of the Galaxy that was fast being altered into a likeness of Cybertron itself by the Cybertronian Empire, a race of later generation Transformers that evolved while the earthbound Autobots and Decepticons were deactivated. The events of this series were actually set in motion with a crossover from the G.I. Joe comic books #138-142, in 1993. Megatron returns to reclaim his leadership off Bludgeon and by the end of the series joins with Optimus Prime to fight against the G2 Decepticons and their genetic offshoot, the Swarm.

The series ended with an epic battle between the "Generation 1" Transformers, the Cybertronians and the Swarm.

The final page reveals the Empire's true scale as its leader, identified as the Liege Maximo, dismisses the final battle as insignificant to his Empire as a whole. He also remarks that Megatron, the Decepticon leader, is more like an offspring than an ancestor to him implying the Empire precedes even known Transformer history.

The story was concluded later by Simon Furman (the same writer for the Generation 2 comics) for a fan convention in the UK called Transforce. The first part of the story--called Allignment--came out in 2002, with the last part coming out in 2005. While mostly a text story, it did include art by veteran Transformer comic artists such as Lee Sullivan, Andrew Wildman, Geoff Senior, Jeff Anderson, and Lew Stringer. In this series, the Autobots face off against the Generation 2 Liege Maximo to stop his attempts at God-hood with many big name characters (including Furman's favorite character) being killed in the process

Since Allignment was not published by an "official" comic book publisher, there is a question as to whether or not it is considered part of the Generation 2 cannon. However, as Allignement was written by the same person who wrote the original comics--and the chances of a continuation of the Marvel comic storyline seems extremely improbable--it is as close to official cannon as possible.
