Fleur Delacour was my favorite character of the entire series for a while. Partly because I loved how, even though everyone around her reduced her to her physical traits that she had no control over, she was fierce and used it as a weapon. I think people often forget that the Goblet of Fire was meant to pick the best candidates from each school, which meant that Fleur was the best warrior fit to represent her school in the magical item's eyes. I would love to befriend her, train with her, and keep gross people who are attracted to her Veela allure away from harassing her. I was so happy when everyone else got on her side after Bill's attack, both readers and the Weasleys, and realized how fierce she truly was. I can't imagine how hard it must have been to live in a foreign country where my soon-to-be in-law's made fun of my accent because I was a quarter Veela and they were jealous of my heritage?
Tonks on the other hand felt like every 2D YA heroine ever. She's clumsy, check. She has an eccentric part of her that makes her appearance different, check. Everyone's obsessed with her love life, check. She falls in love with a werewolf, check. She didn't truly feel like a 3-dimensional until the last book, in my eyes.
