Did you mean: the only anime I watched and then cried at the ending. Okay I love sun and moon. It was my first pokemon game, sun to be specific. I beat Sun and Ultra Moon and am playing Moon and gave my brother Ultra Sun.
Unwinnie, I would have to say (this is a very close one) probably Lillie. She is an absolute angel and didn't deserve the crap that happened to her. I also quite like Gladion because he is actually a really good character and not just edgy boy, and Hau, because he love malasadas and he is really fun to battle and just really nice in general. I'm glad he was in the anime at least.
