Block prevents the target from switching out. The effect only applies as long as the user is still in battle. The affected Pokémon can still switch out using Baton Pass, but in that case, the Pokémon that switches in will become trapped.
If the user switches out using Baton Pass, the effects of Block will still apply to the target. Also, if the target is Roared at or hit with a Whirlwind, they will still be switched out.
If a wild Pokémon uses Block on the player's Pokémon, the player will be unable to escape, unless the player's Pokémon has Run Away.
