Here's what happens when a Pokemon uses Mean Look:
* The opponent's Pokemon is prevented from switching out. This means they are forced to stay in the battle, even if they are about to faint or are ineffective against your current Pokemon.
* The effect persists until the Pokemon using Mean Look faints or is switched out. This means that even if the opponent uses a move like U-turn or Volt Switch, they will still be forced to stay in the battle.
* The opponent's Pokemon can still use moves. They can still attack, use status moves, etc., but they cannot switch out.
* The effect can be removed by certain moves or abilities. Some moves, like Substitute or Baton Pass, can remove the effect of Mean Look. Some abilities, like Shadow Tag, can also prevent switching out.
Strategies for using Mean Look:
* Force a Pokemon to take damage. This can be useful if you have a strong attacker that you want to keep in the battle, or if you want to wear down the opponent's Pokemon.
* Prevent the opponent from using a strategic switch. This can be useful if the opponent is about to switch out a Pokemon that is weak to your current Pokemon.
* Set up for a sweep. If you can use Mean Look to force the opponent's Pokemon to stay in, you can use this opportunity to set up your own Pokemon with buffs or status moves to prepare for a sweep.
It's important to note that Mean Look is not a very common move, and it can be risky to use. If your Pokemon faints before the opponent's Pokemon is forced to switch out, the effect will be lost.
