For me it goes like this;
1. Wallace = Was not too difficult but still posed a threat with that damned
no matter which starter I picked...& his wardrobe is awesome plus he has a notable role in the story which I liked, a truly respectable Water Type pokemon trainer...2. Flannery = She was a very rare case being inexperienced & under training from her father but like Blaine she uses the Fire Type as her themed type but more important then that, though she was inexperienced, she had still posed a decent threat even if it all was with Torkoal & even her character design was unique compared to what I was seeing before hand...
3. Winona = She is here just cause she is the better to me among the remaining Gym Leaders & because her Gym is the 1 in Fortree City which is just awesome in it's own respects...
& to wonder, it's Hoenn, meh...
Maybe Wallace.
