Actually, this reminds me of the villain vs. antagonist category issue. IMO, Trixe, the Flim-Flams and Gilda classify as antagonists whilst Discord and Ahuizotl are true villains. Discord is interesting in that he has two appearances as a villain in non-in-universe chronological order, in Return of Harmony and in Princess Twilight. However, that doesn't stop him from being a villain who has appeared twice as a villain.

So, thinking about it, yeah, Starlight would be the third villain who is still a villain to have a return appearance in non-consecutive episodes.
