Given the extremely slim chance of bumping into them as Roaming Pokémon though, players are still recommended to save beforehand and turn off Autosave, just to secure a chance for getting the Legendary or Mythical Pokémon during the initial Set Encounter. However, in Pokémon Brick Bronze, Legendary and Mythical Pokémon battled in Set Encounters are available as Roaming Pokémon from version 0.10 update on 20th January, 2017 onwards, regardless if the player succeeds or fails at capturing the Pokémon during the initial encounter. If the players failed to capture them, they may only have a second chance after defeating the Regional Pokémon League.
In the core series games, most of these Pokémon can only be captured once - the player would have to trade for more if he or she wanted more of them. Many of these Pokémon are worshipped as gods by particular groups of people in the Pokémon world, due to the fact that these particular Pokémon have unique powers and representation of different items an example would be Groudon, who represents the lithosphere and supposedly has expanded the land.
Legendary and Mythical Pokémon are renowned for their stats and performance in battles.
