In my headcannon, Twylight faced Marer Do Well; forged from her darkness as well as the darkness of Applejack, Rarity, Pinkie, and Applejack. And only Rainbow can defeat the monster.
And Twylight face Midnight Sparkle. One version forge from Sci-Twi’s darkness. Beating her with help from Sunset. And also a Midnight Sparkle forge from her own darkness. And beating her thanks to Sunny Starscout’s belief.
