Earthforce

Earthforce is the name of a cell of Autobots commanded by Grimlock stationed on Earth to counter the rising threats of Megatron, Starscream and Soundwave, and Shockwave and their respective armies. Earthforce's base of operations is in northern Canada. They get into lots of not-so-serious hijinx.

(More importantly, it's the source of a huge continuity trainwreck in the latter issues of the Marvel Comics UK series.)

Continuity problems
The Earthforce stories share much in common with the main Marvel Comics UK continuity from which it branched. Optimus Prime is in his Powermaster form. Grimlock has recently revived his Dinobots and several Autobots with Nucleon. Many threads tie directly in from previous stories, such as the remaining Wreckers from Time Wars and their various dramas with the Mayhem Attack Squad.

However, many of these tie-ins were written in advance of them actually occurring in the continuity proper. It appears to the reader that writer Simon Furman knew vaguely what was going to happen in the future of the comic, so although he wrote these stories with this future in mind, when these links came to be, there was no possible place or loophole for these events to occur. For example:
 * Galvatron II could not have possibly awoken several Autobots on the Ark prior to the Unicron War.
 * Megatron, Starscream and Soundwave, and Shockwave could not possibly have been feuding on Earth.
 * The second Decepticon Civil War did not include a third faction lead by Megatron.

It's possible, had the Marvel Comics series continued, Furman would have been able to shoehorn in a place for these stories. But it didn't, and he could not.
