Here's why:
* Level Difference: Zapdos is a powerful Legendary Pokémon, and even at lower levels, it will significantly outclass a level 12 Charmander.
* Type Disadvantage: Charmander is a Fire-type, and Zapdos is an Electric/Flying-type. This means Zapdos will have a type advantage, dealing more damage and taking less damage from Charmander's attacks.
* Movepool: At level 12, Charmander likely doesn't have access to powerful moves that can effectively damage Zapdos.
* Stats: Zapdos will have significantly higher stats in every category, including Attack, Special Attack, and Speed.
Possible Strategies (Highly Unlikely to Succeed):
* Status Effects: Focus on using moves that inflict status ailments like paralysis or burn on Zapdos. This can weaken it or prevent it from attacking effectively.
* Escape: If the battle seems hopeless, use an escape move to retreat and avoid a wipeout.
* Teamwork: If you have other teammates, even if they are low level, they can help distract Zapdos, allowing you to land some hits.
Overall: While it's not completely impossible, defeating Zapdos at level 12 with Charmander is a very difficult challenge. It's highly recommended to level up your Charmander significantly before attempting this battle.
