Princess Twilight Sparkle is a reimagining of the first and second episodes of the fourth season of My Little Pony: Friendship is Magic.
When Princess Celestia and Luna mysteriously disappear, Twilight and Optimus seek out their kidnapper as well as see visions of the past and learn about the mysterious Tree of Harmony.
- The Plunder Vines don't exist in this reimagining. Instead, the main antagonist is Thunderwing, whose mission is to destroy Princess Twilight Sparkle so that the Magic of Friendship will die.
- Instead of seeing Princess Luna turning into Nightmare Moon, Optimus and Twilight will see Megatronus turning into Megatron.
