- Ascended Fanon: In a way. In Fallout 4, a character named Redeye was added in the Nuka-World DLC Pack that is one huge Shout-Out to the fanfic.
- Approval of God: Kkat enjoys quite a few of the spinoffs and fanmade works created in the wake of her story. This includes animations, games, Recursive Fanfiction, and plenty more. Sometimes she links her fans and followers to them in her blog posts, other times she just mentions them in interviews.
- One-Hit Wonder: For its incredible success, it's also Kkat's only published work of fiction (barring a non-canon side story within the same universe that focused on Daring Do), at least partially because she isn't sure she can measure up to reader expectations, according to one interview:I may write other stories not-related to Fallout: Equestria. I have a few vague, half-formed ideas. But I face the problem that nothing I write will really compare to what I have just completed. Fallout: Equestria is grand, powerful, meaningful and epic on a scale that I could never duplicate [and] wouldnt want to try.
- Unintentional Period Piece: Clearly, this was written during the hiatus between FiM's first two seasons, long before canon Equestria really started to change dramatically.
- What Could Have Been: Kkat planned, but ultimately chose not to go through with, a sequel that would focus on the remaining members of the main group seeking out the other new Element bearers, while Littlepip acted as Mission Control from her pod.
- The Wiki Rule: Here, needs love.
- The cover art for Fallout: Equestria was originally an unrelated piece of fanart titled "Foalout 3", and was drawn before the fanfic was written. See here.
