My Little Pony: A New Generation, my opinion on Sunny becoming an alicorn. · 4:30pm Sep 26th, 2021
I really really hope that because her alicorn form in glowing and transparent is because it's fake and temporary.
If not then I'm pretty sure it's just writers probably going lazy and choosing a very easy route. They probably didn't want to create a whole arc/seasons of Sunny becoming worthy of becoming an alicorn so they just gave it to her.
