Legendary Pokémon

Legendary Pokémon, in general, are Pokémon that have extremely powerful stats. In the games, you typically have one chance to catch them, and even then, catching them is a major challenge!

In the anime, Legendaries are considered "gods" in the Pokémon universe, appearing only to special trainers.

In the Japanese version, there are two distinct terms used to refer to those pokemon which are called "Legendary" in English. One, 伝説のポケモン (densetsu-no Pokémon, lit. legendary Pokémon), refers to those which feature prominently in legends, such as Groudon and Kyogre. The other, 幻のポケモン (maboroshi-no Pokémon, lit. illusory Pokémon), refers to those so rarely seen that some question their very existence, such as Mew and Lugia.

These Pokémon are considered Legendaries:

Generation I

The Legendary Pokémon of Generation I can be broken into two groups: the Legendary Birds or Avians, and the Mew-based Legendary Pokémon, here classified as "other" Legendary Pokémon.
