In addition to the obvious effects on water and fire attacks, rain changes the way a few other Pokemon moves work. Restorative moves like Synthesis, Moonlight, and Morning Sun recover only 25 percent of a Pokemon's hit points when it rains. The powerful Solar Beam gets a real damper, as it requires two turns to charge during rainy weather.
Thereis also a large number of abilities that benefit from the rain. Manaphy (still one of our favorites) has the Hydration ability, which uses the rain to cure any status problems it might have. This nifty ability also allows it to use Rest without a sleeping penalty. Several water Pokemon have the Swift Swim ability, which doubles their speed in the rain. A water Pokemon with well-rounded stats, like Kingdra, becomes even more of a handful in rainy weather.
