Air Lock (エアロック) is an ability exclusive to Rayquaza, introduced in Ruby and Sapphire. This ability's effects are identical to Cloud Nine.


This ability negates the effects of weather. When Rayquaza is brought out, the message  "The effects of weather disappeared." appears after Generation V. The effects of Drought, Drizzle, Snow Warning and Sand Stream fail to activate and the moves Sunny Day, Rain Dance, Hail and Sandstorm fail if used. However, Desolate Land, Primodial Sea and Delta Stream still have their other effects if triggered before Rayquaza was sent out.
