I like to use my imagination during battles. For example i was playing on showdown using a rayquaza. Even though rayquaza has air lock, the battle window still displays the rain/sun background. So i imagined that in the pokemon world, when rayquaza uses air lock, you can still see weather, but it doesn't have any effect. For example when it's raining, you still see the water raining all around you, but your clothes don't get wet. I think it's pretty cool.
