Description
The Princess Korra cometh, behold, behold
A princess here before us
Behold, behold, behold
Behold, behold The Princess Korra cometh
Behold, behold, The Princess Avatar
The Princess Avatar is here
Thanks to Tenzin's advice, Korra and The Mane Six all discover their inner power and spirits, their Elements of Harmony don't come from gems and Korra's true spirit doesn't come from Raava...but them their own hearts and their friendship.
The girls combine their powers and together they destroy UnaVaatu and restore the magic of Equestria which was fading. In the process, Korra has proven herself to posses the integrity, compassion, devotion, integrity, optimism and the leadership of a true princess and earned her wings and alicorn magical powers (which come from the star on her forehead). Thus transforming into the very first Human Alicorn, or "Korcorn" as one of my FanFic reviewers calls her.
At first Korra says she doesn't believe she deserved to become a princess but Celestia reassured her by saying that she did because despite her mistakes, Korra did everything she could to fix it and grew from her mistakes and became wiser.
"Learning to take responsibility for you're own mistakes and fight to correct them is a valuable lesson to learn. You are an inspiration to us all, Princess Avatar Korra"
