>>31537535>It's not fucking development if a character developsAlso, there's a difference from the emotions you FEEL and the emotions you EXPRESS. Hau expresses himself happily all the time. He has his own problems, namely not being as strong as he would like, worrying that he won't be Kahuna material when the time comes for him to inherit the role,
getting a crush on Lillie, and wanting to find his deadbeat dad, but he handles them in his own upbeat way instead of angsting about them and trying to gain unnecessary pity from the audience. That doesn't make him hollow at all. It just means he's a kid that's psyched to go on an adventure with his friends and try out different malasada restaurants, and hakuna matata-ing the fuck up while he does.
I think the problem you have is that you assume that more complexity = higher quality character, when that doesn't have to be the case. Sometimes a good character is someone who's able to keep the group going with their positivity, while also facing their own fights. Pokemon doesn't need to be a soap opera where we have a scene with Hau breaking down into tears or completely losing his temper, because that would be extremely out of character for him as a person who tends to be optimistic whenever he can, and keeping your characters reasonably within character is more important for writing than making every character experience/display every spectrum of emotion just for cheap diversity.
