Quote From: precitaWhat do you think this character will do? I don't think she's a coordinator.
Hopefully she is an active female battler. Its a nice change of pace from Dawn, and since Misty hardly ever battled and wasn't very active as a female protagonist, we would be seeing a female battler for the first time.
Other than store Pokemon in her hair and swing around like a monkey, we really don't know what she'll do. Black and White is introducing the Pokemon Musical, so I assume will see that sometime during the series. Maybe it will replace contests during this series and Iris will do a Pokemon Musical circuit or something. It would actually be kind of interesting if two people actually did the gym battles at the same time as they traveled though.
