A Horde Encounter (Japanese: 群れバトルHerd Battle) is a type of Pokémon battle introduced in Pokémon X and Y. Horde Encounters consist of the appearance of a group of five wild Pokémon. Unlike wild Double Battles, Pokémon in a horde are usually of the same species, but may include a single instance of a similar Pokémon or counterpart of a different species.
Pokémon in hordes are at approximately half the level of other Pokémon in the same area and in some routes may be a lower evolutionary stage of Pokémon that normally inhabit the area (such as a horde of Geodude occurring in areas dominated by Graveler). Pokémon encountered in hordes may also have their Hidden Ability. Some Pokémon can only be found in hordes.
Hordes are encountered randomly by running through the tall grass, or they can be forcefully initiated using Honey or Sweet Scent; however, Honey and Sweet Scent cannot be used unless the weather is clear in the overworld. As in all wild battles, a Trainer cannot throw a Poké Ball unless there is only one wild Pokémon remaining.
The player's moves in a Horde Encounter act as if the player was in the center of a Triple Battle, except with all five other locations being treated as opponents instead of allies. A move like Tackle would only be able to hit one opponent, while a move like Rock Slide would be able to hit all five.
A Durant horde may include one Heatmor, and vice-versa.
A Plusle horde may include one Minun, and vice-versa.
Mixed hordes with enemy species
If a mixed horde includes Zangoose and Seviper or Heatmor and Durant, the wild Pokémon will ignore the player's Pokémon; instead, each Pokémon will attack the Pokémon of the other species with the exception of status moves. Once all the Pokémon of one species have fainted, the rest of the horde will begin attacking the player's Pokémon.
Unlike in Triple Battles, there is no range limit; a Pokémon in a far-left position can attack a Pokémon in a far-right position.
