Level/Games/Spin-off games

In the Pokémon Mystery Dungeon series
In the Pokémon Mystery Dungeon series, level functions similarly to the core series. Like in the core series, each Pokémon's level, ranging from 1 to 100, depends on how much it has. When a Pokémon gains a level, its stats increase slightly and it may try to learn a new move. The moves that can be learned by each Pokémon, and the exact levels they will try to learn them, are the same as contemporaneous core series games. In order for some Pokémon to evolve, a minimum level is also required. However, evolution does not occur automatically, requiring access to specific places instead.

In the Mystery Dungeon games preceding Pokémon Super Mystery Dungeon, Pokémon require significantly more experience to level up than in the core series games, while in Super Mystery Dungeon, experience is gained the same way as in the core series games.

A number of dungeons across the series temporarily set the team's levels to 1 or 5 when entered. Their levels are restored to normal once the dungeon is exited.

A or  can be used to increase a Pokémon's level. A can be used to decrease a Pokémon's level. A Pokémon holding a or  will gain experience points whenever it takes damage (the amount of experience gained this way varies between games).

In Pokémon Shuffle
Each Pokémon in Pokémon Shuffle has a level, which increases when it gains enough experience. As a Pokémon's level increases, its increases as well, with how much it increases per level determined by the Pokémon's. All Pokémon begin at level 1, with a maximum level of 10. However, Raise Max Level are able to increase this cap for specific Pokémon, potentially up to level 20.
