Lugia

Lugia (Japanese: ルギア Lugia) is a dual-type Psychic/Flying legendary Pokémon.

It is not known to evolve into or from any other Pokémon.

It is often considered to be closely related to Ho-Oh as a duo, even sometimes as its polar opposite. Silver represents Lugia as "guardian of the seas", and Gold represents Ho-Oh as "guardian of the skies."

Lugia is the version mascot of Pokémon Silver, its remake Pokémon SoulSilver, and Pokémon XD: Gale of Darkness, appearing on the boxart of them all.

In Pokémon XD, Shadow Lugia, codenamed XD001, is a main part of the storyline, and Cipher's ultimate Shadow Pokémon.
