I do hope you guy like this. This was really fun to work on.
Princess Luna, Nightmare Rarity @ Hasbro
And the lights and shadings look great here!!!
Yeah, I'm not going by that. I know it's in the comics, even though I haven't read them, and it's how Nightmare Rarity comes to be. But a moon parasite is way too Venom (from Spider-Man the 90s' cartoon) for me. Besides, I think having Luna be generally jealous of her sister adds a bit of depth to character. Now I love Luna; I think she's an awesome character, but I love Nightmare Moon more. Nightmare Moon was one of the only true villians of the show. Discord just wanted chaos and to have a good time while making Celestia's life difficult. Sombra could only ever hiss out, "Ponies." Chrysalis, just wanted food for her subjets and wanted no one stopping her. Nightmare Moon on the other hand wanted to take way the sun and have ever lasting night. By having only night the land would freeze and everyone would die. That is why, Nightmare Moon is truly bad ass.
The comics do kinda go hand-in-hand with what Lauren Faust said about Nightmare Moon when she was working on the show, though.
Besides, there's no rule that a possession can't happen with some jealousy involved. That just means that the host was willing to let the spirit enter their body in order to gain power. In Luna's case, though, the power wasn't worth the price she paid for it. Especially considering the reaction we see on her face before she becomes Nightmare Moon in the S4 flashbacks.
