Legendary and Mythical Pokémon

Legendary and Mythical Pokémon are Pokémon that are exceptionally rare and often very powerful, who featured prominently in the legends and myths of the Pokémon world. Many Legendary Pokémon are version mascots in the core series games. Mythical Pokémon were originally considered to be Legendary Pokémon as well, but they were implied to be different from Legendary Pokémon in the side series game: Pokémon Ranger: Guardian Signs, and later officially separated in another side series game: Pokémon Super Mystery Dungeon.

Characteristics
Legendary and Mythical Pokémon are renowned for their stats and performance in battles. Many of these Pokémon are worshipped as gods by particular groups of people in the Pokémon world, due to the fact that they have unique powers and representation of different global aspects; an example would be Groudon, who represents the lithosphere and supposedly has expanded the land.

In the core series games, most of these Pokémon can only be captured once - the player would have to trade if they wanted more of them. If the players failed to capture them, they may only have a second chance after defeating the Regional Pokémon League. However, in Myth Worlds (as in the original PBB) Legendary and Mythical Pokémon appear in Set Encounters throughout the game and are then made available as Roaming Pokémon, regardless of whether or not the player succeeds in beating or capturing them during the set encounter.

Given the extremely slim chance of encountering them as Roaming Pokémon, it is highly recommended that players turn off Autosave and manually save the game, in order to secure a chance for getting the Legendary or Mythical Pokémon during the initial Set Encounter.

There are some Legendary and Mythical Pokémon which are not found via battles, nor available as Roaming Pokémon. The three Lake Guardians; Uxie, Mesprit and Azelf can be dug up as Fossilized Eggs in Lagoona Trenches, and they are also the only Legendary Pokémon available in Eggs, while multiple Manaphy can be obtained by picking up Manaphy Eggs washed ashore when the event is held on Rosecove Beach. (This event is yet to occur in Myth Worlds.)

Legendary and Mythical Pokémon cannot evolve, other than the newly introduced Cosmog family. They also cannot breed, except the "Sea Guardians" Phione and Manaphy - both of which produce Phione Eggs when bred with Ditto.

In the Pokédex for each generation portion, Mythical Pokémon typically appear at the very end of the game, and Legendary Pokémon immediately before them, except Victini, which appears right before the Unova Starter Pokémon.

Strategy
Legendary and Mythical Pokémon are notorious for having extremely low catch rates. To catch them, start by throwing a Quick Ball, which has 5× catch rate in the first turn. If it fails, weaken the Pokémon with attacks that will not make it faint (e.g. False Swipe) until its health bar is in red.

Inflicting a status condition like paralysis, frozen or sleep/hypnosis also increases the catch rate. It is strongly advised not to use damaging status changers like burn and poison as these can ultimately knock the Pokémon out.

Once the Pokémon is in critical health and is asleep, paralysed or frozen, start by throwing the most effective Poké Balls according to the situation until it is caught. For example, Dusk Balls are the most effective at night or in caves with the 3.5× catch rate.

Elemental Balls (not in Myth Worlds as yet) can also be good backups by using the Pokémon's type to the player's advantage, but they cost double the price of Dusk and Quick Balls while having the same catch rate of a Dusk Ball in maximum effect.

In other games many veteran Pokémon Trainers would also stock up on Timer Balls as a last resort, because the catch rate of Timer Balls gradually increases as the battle drags on, capping at 4× after 10 turns; however, Timer Balls are not available in Myth Worlds.

is a widely used attack for catching Legendary and Mythical Pokémon, because it is a unique attack that will never render the opponent unable to battle, always leaving it with 1HP, although it does not affect Ghost-type Pokémon. TM54 False Swipe is available for purchase in BP Shop, Colosseum Marketplace for 45 BP. Certain Pokémon may also learn this move via.

Mythical Pokémon
Here is a list of Mythical Pokémon which have appeared in-game. Italics indicate that the Mythical Pokémon can only be seen as of now. Hoopa is the game mascot of Pokémon Brick Bronze and is mentioned a few times in-game, before eventually being summoned in Demon's Tomb **. '' ** As the Prison Bottle is destroyed, Hoopa is incapable of interchanging between its forms. Hoopa Unbound caught in Demon's Tomb will NOT revert into Hoopa Confined even after 3 days have passed or retrieving from PC. On the other hand, successfully catching Hoopa Unbound unlocks Hoopa Confined as Roaming Encounter, which CANNOT transform into Hoopa Unbound if captured. ''

Trivia

 * Phione's status as a Mythical Pokémon is currently disputed, with several pieces of evidence and even official statements often contradicting each other's viability.
