Pokémon Scarlet & Violet

Hordes
As you travel through the Paldea region, you will often find Pokémon within group of five, with 1 Pokémon being the leader and the other four being its subordinates. These can be either specific Pokémon based on its evolution chain, or it can spawn random Pokémon from the local area. While you aren't able to battle all the Pokémon at once like was seen in some prior games, it does provide some good spawns for getting materials.
Bisharp Evolution
Another use for this is with Bisharp's evolution. Bisharp as a Pokémon is unique in that the ones that lead these hordes have got the special item, the Leader's Crest. If you have a Bisharp defeat three of these then level it up, it will evolve
