– Sunset Shimmer, in Equestria Girls
Sunset Shimmer did not appear in Fallout: Equestria (as the story was completed two years before Equestria Girls was released). It is unknown if she ever left the Human world, or if the events of Equestria Girls even occurred in Fallout: Equestria's universe.
She has, however, made appearances in Fallout: Equestria sidestories.

Sunset Shimmer, first mentioned in Chapter 12, was apparently present in Equestria during the Great War, as well as the balefire bombing of the Crystal Empire. It can be deduced that Sunset Shimmer returned to Equestria from her time spent in the human world, and remained there for a time until the end of the Great War.
During the sacking of Poneva city, Lightning Dust apparently knew her well, murmuring Sunset Shimmer's name, among others, as she watched the Crystal Empire become consumed by a balefire mushroom cloud.
It is unknown whether or not Sunset Shimmer survived the balefire bombing of the Crystal Empire.

In the story, Sunset Shimmer appears to have remained in the Equestria Girls Universe, where somehow only a few years have passed instead of 200.
The character Ruby Starlight communicates with Sunset through the book that Twilight Sparkle used, but the interactions so far have been brief after Sunset was told Twilight was dead. Later during her time in Junction Town, Sunset requests assistance from Ruby with problems plaguing the Equestria Girls universe.
She and the rest of the Humane Seven appear when Ruby and her party travel into the Human World. She helps run a settlement called Freetown, which has been caught between the warring factions of the Crimson Legion and Enclave.
