Game of thrones daenerys
She helped the North defeat the Night King and save the world.
She found allies in the Martells and the Tyrells.
It seemed like Daenerys had learned from her prior mistakes when she did make it to Westeros. Check out IGN's speculation on Daenerys's villainous trajectory from the Season 6 episode "Blood of My Blood" below: In Meereen she attempted to be just and kind, but when it came time to subdue the mutineers that rose up against her, she destroyed the city and left the entire country behind with a pretty weak support system in order to conquer a different continent altogether. But Daenerys made a mess in Slaver’s Bay, pure and simple, and she never proved herself to be an effective ruler. Game of Thrones never did anything to dissuade us from the viewpoint that she was a hero, not a tyrant. In each of these situations, we rooted for Daenerys to succeed because we saw the world from her perspective, and these people were “evil,” based on her experiences. She burned all of the Khals alive in Vaes Dothrak when they dared try to make her a Dosh Khaleen. She crucified the masters of Meereen in response to their cruel use of slave children to mark the path to the great city. She had the Unsullied kill the masters in Astapor when she became the Breaker of Chains. She killed the warlocks of Qarth and left Xaro Xhoan Daxos (and her handmaiden Doreah) to die in his empty vault. The Breaker of ChainsDaenerys’s entire ascension to ruler of the Slaver Cities has left a trail of blood and bodies behind. Burning Mirri Maz Duur seemed justifiable after what she did to Dany’s family, but it was still a pretty chilling moment for the Mother of Dragons. In that moment, Daenerys learned that giving mercy to those who seem vulnerable can be a weakness - one that robbed her of her husband and unborn son. Daenerys initially tried to show the old witch mercy by trying to save her from the Dothraki, only to have that perceived kindness repaid with a curse.
But let’s not forget the cold-blooded murder of Mirri Maz Duur that led to the dragons being born. “Daenerys became our stereotypical heroine when she walked through the flames, unburnt, with three baby dragons draped around her.
