When a Pokémon with Cloud Nine is in battle, all effects of weather are negated (though the weather itself does not disappear).
When a Pokémon with Cloud Nine is brought out, the message "The effects of weather disappeared." will be displayed.
During extremely harsh sunlight, heavy rain, and a mysterious air current, even if a Pokémon is negating the effects of weather with Cloud Nine, the moves Sunny Day, Rain Dance, Sandstorm, and Hail will still fail if used, and the Abilities Drought, Drizzle, Sand Stream, and Snow Warning will still fail to activate. However, all other effects of these weather conditions are negated by Cloud Nine.
Outside of battle
Cloud Nine has no effect outside of battle.
Pokémon with Cloud Nine
- The Japanese name of this Ability is a double entendre, written so as to suggest ノー天気 nō tenki (no weather), but also homophonous to 能天気 nōtenki (carefree), in reference to Psyduck, originally the only Pokémon (in addition to Golduck) that had this Ability. The English name derives directly from the "carefree" meaning, while still maintaining a weak pun to connect it to the weather.
