I am human, hear me err.
I like to think that if each of the element bearers were possessed by a tantabus, they’d take on a different identity, based on either their element or cutie mark. In the order of their images here, Twilight Sparkle could be Nightmare Mage, Pinkie Pie could be Nightmare Fest, Fluttershy could be Nightmare Bug, Applejack could be Nightmare Nashi, Rainbow Dash could be Nightmare Spectrum, and Rarity could be Nightmare Glass.
