They get lost in dungeons or lose items in dungeons...and you need to rescue them with your rescue force

All 386 Pokémon are obtainable in this game to join your rescue force and are seen by battling them in one of the almost 50 dungeons, some of them with massive Legendary Bosses at the end of them such as Rayquaza, Deoxys or Mewtwo.
