These trainers will have stronger Pokémon and higher levels compared to the first battle. To trigger a rematch, players can either wait for a certain amount of time to pass or defeat the Elite Four and Champion again.

Swamp and marsh areas tend to be foggier due to the high levels of moisture present in these environments. The water in swamps and marshes evaporates easily, creating a humid atmosphere that is conducive to fog formation. Additionally, the dense vegetation in these areas can trap moisture and prevent it from dissipating, further contributing to the foggy conditions. The combination of these factors makes swamp and marsh areas more prone to fog compared to other environments. **
