"Introducing Rainbow Power Queen Twilight Sparkle!

This is what I think Twilight Sparkle SHOULD have looked like in Season 9: Episode 26: The Last Problem. She has the magic of Celestia, Luna, and herself inside of her. As a result, she's taller than Celestia, and is more powerful than Celestia and Luna combined. Her ruling Equestria I think is basically like a second ascension, so the 4 wings and 2 horns make her extra special and powerful. The Rainbow Power appearance is her friendship side. She can fly much faster and her weather manipulation abilities are much more powerful than the average Alicorn, her Earth Pony strength is stronger, and the 2 horns allow her to cast spells faster than the average Unicorn or Alicorn. She can even use her horns to combine spells in ways that Unicorns or Alicorns can't. However, the extra wing power and horn drains her energy and magic faster, but she already has a LOT of energy and magic reserves already, so the increased energy drain shouldn't be much of an issue."
