Underleveled Pokémon

In the games, underleveled Pokémon are evolved forms at a level less than the required level to evolve. This is often a result of game balancing in the early games, in-game trades, and special events. Occasionally NPCs will also battle with underleveled Pokémon.

Hidden Grottos

 * Herdier - Floccesy Ranch
 * Amoonguss - Pinwheel Forest, Abundant Shrine, Route 22
 * Leavanny - Lostlorn Forest
 * Muk - Unova Route 9

Friend Safari
The Friend Safari in Pokémon X and Y is an unusual location, in that Pokémon that appear are dependant on registered friend codes within the memory of the 3DS console. As a result, not all Pokémon are obtainable to all players without a suitable friend code. All Pokémon found in the Safari are level 30.

Generation VII

 * Kadabra and Drifblim are also obtainable underleveled from the Poké Pelago.
