However, there are a few ways to effectively "lose" a battle:
* All your Pokémon faint: This is the standard way to lose a battle. If all your Pokémon faint, you lose and the other trainer wins.
* Running away: You can run away from a wild Pokémon encounter or from a trainer battle, but this only works under certain conditions.
* You can always run away from a wild Pokémon encounter, although there are some situations where the Pokémon will block your escape.
* You can only run away from a trainer battle if the other trainer is a wild Pokémon trainer, not a human one.
* Forfeiting in specific situations: There are some specific game scenarios where you might be given the option to forfeit. This usually happens in the context of a tournament or competition, but it's not a general gameplay mechanic.
It's important to note that even if you "lose" a battle by running away, you won't actually get any negative consequences.
So, while you can't formally forfeit a battle in Pokémon, you can effectively "lose" by either having all your Pokémon faint or by running away in specific circumstances.
