- In Star Trek: Mirror Wars, Earth was the location of the Battle at Mirror Earth.
- According to William Shatner's novel Spectre, Alliance ships destroyed the Imperial fleet in their version of the Battle of Wolf 359, and proceeded to reduce mirror-Earth to a barren wasteland, vaporizing the Great Lakes and other landlocked bodies of water. The Alliance enslaved Terrans.
- Star Trek: New Empire: Earth was similarly ravaged in this continuity, though not rendered entirely lifeless. Criminals, pirates, miners and various aliens used the barren Earth as a base of operations for different purposes in the late 24th century. Between 2375 and 2385, Stephen April attempted to rejuvenate Earth using a Genesis device, with apparent failure; however, by 2407, Terrans had begun to re-colonize their world.
- In Before In a Mirror, Darkly, the Xindi sent a probe to attack Earth in 2153, destroying an area between Florida and Venezuela, killing 7 million people. Unlike the core alien worlds of Denobula, Tellar, Andoria, and Vulcan, Earth was not put into lockdown, though aliens not already on Earth could only enter with the permission of a senior official, such as a Starfleet captain. Terran mobs attacked aliens, even in the relatively calm London, with Starfleet Command ironically being one of the few places an alien would be safe.
