This is the thread to discuss what you liked and disliked about Dawn's character while she was on the show, her story, her pokémon team (though if you solely want to talk about Piplup, please use the designated thread), etc.
Dawn was my favourite out of the girls mostly because she was the most realistic, compelling and relatable. She was realistic in that the writers didn't make her out of an archetype, didn't use that one facet as a dominant character trait. She was sometimes funny, sometimes vain, sometimes pensive, sometimes sad, sometimes angry, sometimes selfless... much like none of us are just one type of personality. Her story of feeling like she wasn't good enough, her doubts, her struggle, everything about her story was easy to relate to and compelling. I liked her diverse pokémon team and her contests were much more interesting and different than the contests in AG.
Where I think that Dawn's weakness laid was in her interactions with other characters. Her friendship with Ash was great, as was her rivalry with Ursula and comic moment with Barry and Conway, but her friendly rivals fell flat and her interactions with Brock were next to non-existent. Also, the realism that made her, in my opinion, a very complex and interesting character is a double edge sword as it could leave the audience feeling disconnected from her because they were not able to pinpoint specific traits about her.
