Earth-120185

''Within the multiverse of Marvel Comics, each iteration of Earth is given a numerical designation that serves to represent that universe. Earth-120185 is the universe in which the UK incarnation of the Transformers comic book series occurred. It is, at its core, largley similar to the Marvel US, but with many additional events, and some divergences, most notably the reconstruction of the Autobot Bumblebee into Goldbug.''

The essential difference between Earth-120185 and other universe in the Marvel Multiverse is that it became the battleground for the war between the Autobots and Decepticons. There are some elements that exist across both Earth-12085 and the mainstream Marvel Universe (Earth-616), such as Spider-Man, Reed Richards, Nick Fury, Dum-Dum Dugan, Godzilla, the Savage Land, U.S. 1 and Dazzler, but for unknown reasons, these beings did not factor into the Transformers' war. Earth-120185 is also home to Action Force.

Per the original state of its timeline, the 21st century of Earth-120185 saw Unicron attack Cybertron in 2006. Following Unicron's defeat, the Galvatron of this era travelled back in time to 1987 and remained there for two years, ultimately resulting in a rift in the fabric of space and time that destabilised the universe. Although this rift was eventually sealed, Earth-120185's timeline was left permanently altered, it's future warped into a dark shadow of its former self and diverged off from the primary timeline, becoming an alternate universe of its own.

It is unclear whether or not the adventures of the Autobot Earthforce take place on Earth-120185, or a further divergent Earth.
