Also fought around here
This game's documentation doesn't say where 25 of its 678 fights happen, so those trainers are on no part of this walkthrough; they are all on the Trainers page. It also doesn't say when 7 of its areas open up, so they are listed together in the last part rather than guessed into the story.
