Moxie

Moxie is an ability in the Pokémon series that boosts a Pokémon's attack power under certain conditions. When a Pokémon with Moxie knocks out an opponent, its Attack stat increases by one stage, enhancing its physical attack power for the duration of the battle. This buff can stack, making Moxie particularly potent in battles where a Pokémon can continuously knock out opponents, leading to progressively higher attack power.

Here are some other interesting facts about Moxie:

Introduced in Generation V: Moxie first appeared in Pokémon Black and White. It has since become a sought-after ability for many physical attackers.
Strategic Use: It is often more beneficial for fast, hard-hitting physical attackers that can secure knockouts quickly, gradually snowballing their attack power.
Common Pokémon with Moxie: Some notable Pokémon that can possess this ability include Gyarados, Salamence, Krookodile, and Heracross. These

Effects

This Pokémon's Attack rises one stage upon knocking out another Pokémon, even a friendly Pokémon. This ability does not take effect when the Pokémon indirectly causes another Pokémon to faint, e.g. through poison or spikes. If this Pokémon knocks out a Pokémon with mummy, the former's ability will change without taking effect.
