White Smoke  is an ability intoduced in Generation III. It functions similarly to the ability Clear Body. In battle, a Pokémon with this ability will not be affected by moves that lower statistics (Growl, Leer, etc). If the user is leading the party, the chance of a wild encounter is reduced by half.
