United Federation of Planets

In a parallel universe, the United Federation of Planets, or simply the Federation, was a meta-government of which many planets and species were members by the 23rd and 24th centuries.

Some members of the Federation were the humans, the Vulcans and the Deltans, while the Klingon Empire was a close ally of the Federation. The Borg were among the Federation's enemies, having destroyed much of its fleet in a battle at Wolf 359. (COMIC: Assimilation²)

Alternate timeline
In an alternate timeline, the Cybermen, after integrating N-Space with the Federation universe, successfully conquered Mutter's Spiral. Several points in this timeline were visited by the Doctor's TARDIS, as the Eleventh Doctor demonstrated to Captain Jean-Luc Picard what would happen had the Cybermen been allowed to conquer the Borg.

After conquering the Borg Collective in the late 24th century, the Cybermen began a campaign to convert the galaxy. Throughout the 25th century, the Cybermen converted the Klingons of Qo'noS by 2418, and the Vulcans of Vulcan by 2468. By 2533, the Cybermen had conquered Earth and vanquished San Francisco's Starfleet Academy, the last holdout of free humanity. (COMIC: Assimilation²)
