Level/Games/Core series/Disobedience

Outsider Pokémon (Pokémon obtained via trade or distribution) occasionally disobey the player's commands if they are above a certain level. The Badges the player owns determine the maximum level outsider Pokémon can be before there is a possibility for them to disobey. Not owning the region's second Badge means that no traded Pokémon whose level is above 10 (level 20 since Generation V) will obey the player; if the player has the region's eighth Badge, Pokémon will always obey.
