Fallout: Equestria originated as a massive fan-fiction crossover written by Kkat in 2011, merging the dark, post-apocalyptic setting of the Fallout series with the bright world of My Little Pony: Friendship is Magic. The story follows Littlepip as she navigates a nuclear-ravaged Equestria, and it quickly became one of the most famous works in the Brony fandom. Memes surrounding this crossover often contrast the innocence of the original show with the grim survivalist tropes of Fallout, often featuring characters like Littlepip, Blackjack, or Pip-Buck UI elements. Usage ranges from highlighting the absurdity of the crossover to celebrating the deep lore and emotional beats of the fan-made universe.
