Synchronize (ability)

Synchronize is an Ability introduced in Generation III.

In battle
If the opponent causes a burn, paralysis, or poisoning of a Pokémon with  Synchronize, the opponent receives the status condition too. Self-inflicted status conditions (for example through the use of an item) are not passed on.

Outside of battle
If a Pokémon with  Synchronize  is the leading party Pokémon, there is a 50% chance of each wild Pokémon encountered having the same nature.
