[Apollo has come to accept that most of the Pokémon seem to like fighting for fun, but he doesn't have to like it. In his view, fighting's only something that should be done to kill something for food or to defend yourself or others. He has to admit that a life-or-death fight, such as with a bear, is a good challenge and gives him a rush, but he doesn't find it fun per se.]
If you're in Cherrygrove City now [as he assumes from how long it's been since Dorumon arrived], I think the closest gym to you is in Violet City. I've never been there though, so I don't know what it's like, but the other gyms that I've been to were really hard for the Pokémon with me to beat. The Pokémon who's with you will need to train and get stronger if he wants to win.
