Flawless Sparklemoon is a My Little Pony: Friendship is Magic fan character created by YouTuber Tamers12345 for his My Little Pony animation series. Debuting in the episode "The Death of Twilight Sparkle", Flawless is created when Twilight Sparkle attempts to lift a bonding spell cast on Trixie by Princess Luna. Proclaiming herself to be a fusion of Twilight and Trixie's best attributes – Twilight's intelligence and magic skill, and Trixie's charisma – without their respective flaws, Flawless becomes a recurring antagonist, attempting to murder Twilight and Trixie to impose her superiority.

Flawless is a unicorn with slate blue fur and purple, starry eyes. She has long purple and violet hair, and is always seen wearing a black top hat and cloak. Fanart often depicts her with a cutie mark that is some combination of Twilight and Trixie's marks. Her signature ability is being able to replace herself, in any point of time, with someone else, which allows her to evade attacks, put opponents in deadly situations, and even resurrect herself from the dead, as seen in "Shattered Harmony".
