If I missed something, please let me know, so I can fix it.
1. Shimmering Spectacle
and here's her devientart page
(and if you like, you can associate her DA page with the artist tag)
3. Alicorn and Female/futanari
4. she's a cloned daughter of 3 known alicorn/unicorns (Twilight Sparkle
, Sunset Shimmer
, Starlight Glimmer
, the way she was born was like this: the 3 ponies wanted a clone of their bodies in one, so they started doing some DNA testing, by taking a sample of each of their blood and with some magic they were able to magnify into the nucleus of their cells to see their helixes, then they took each of their helixes, studied witch part is the right one and as they pick the 3 parts they proceed to cut a percentage of the exact part of their DNA (33 percent from each of the 2 unicorns, 34 percent from the alicorn), they reconnect the parts into one, then with cloning technology (Sunset was able to learn this from the human world and share it to Twilight and Starlight) they then put the reconfigured DNA back in Twilight's cell with nucleus and with sunset's and Starlight's cells with no nucleus they were able to fuse the 3 cells into one, and right after it fused, it started to divide, and as it's dividing, Twilight then puts the embryo into the cloning tank, they then start to monitor the fetus as time goes on, then when the fetus was developing they continue to monitor it's progress, then after nearly a year they consider their daughter healthy enough to "birth" her out of the tank, and finally she's very much alive.
Note: as time goes on, I'll have to put in some more updates.
