It’s Twilight time! Post-ascension, Twilight starts out with just wing nubs that grow in over time. The middle version is when they had just become big enough for her to fly.

Alicorns are the most primal of Ponykind, with all other races descending from them. Modern ponies aren’t carnivorous, using their fangs for defense, but Alicorns are. The Royal Line has taken a vow of Herbivory as part of their devotion to peace, but fending off her new Alicorn nature is definitely hard for Twilight at first. It is doable with the Sisters’ and Fluttershy’s help, though.
