True. Dawn didn't take losing well and lead to good development, but Dawn wasn't exactly a sore loser, maybe once during Hearthome but she grew out of it. I'm talking a girl that hates losing and refuses to accept that there are those stronger then her. I want a stubborn sore loser like that. She could be fun. Like have her be sour until she gets her revenge/justice.
Interesting enough, Dawn already knew what her goal was from the start. I think Iris and Misty were the same same as well, and May wasn't so bad about it, it was only Serena who took a very long time. But it's over now and she's setting out great so far.
