Lugia (7 Eleven)

These Pokémon were distributed to players who inserted a serial code that was given away at 7-Eleven stores in Japan over two different distribution periods. The serial codes for Pikachu and Pancham were available from July 18 to 31, 2015 and the serial codes for Lugia and Latios were available from August 1 to 16, 2015. 

The serial codes for Pikachu and Pancham could be used from July 18 to September 30, 2015 and the serial codes for Lugia and Latios could be used from August 1 to September 30, 2015. The Pikachu and Pancham are based on Ash's Pikachu and Serena's Pancham.

To obtain the serial codes, players had to compete in a stamp rally. To collect a stamp players had to connect their Nintendo 3DS system to a 7Spot using the Nintendo ZoneViewer, touch "DS at 7SPOT", then touch "Pokémon DS Rally" (Japanese: ポケモンDSラリー), and then touch the "Get Stamp" (Japanese: スタンプを押す) button. Upon touching the "Get Stamp" button the Nintendo 3DS system obtained a virtual stamp. Players were only able to obtain one stamp per store per day. Players who had two stamps could choose which of the two Pokémon available during that period that they wanted, then were given a serial code for that Pokémon. If the player decided to save the page, they could access it later, although promotional material recommended that players write the serial code down.

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 part of the Tower duo with Ho-Oh, even sometimes as Ho-Oh's polar opposite. Silver represents Lugia as "guardian of the seas", and Gold represents Ho-Oh as "guardian of the skies." 

Lugia is the game mascot of Pokémon Silver, its remake Pokémon SoulSilver, and Pokémon XD: Gale of Darkness (as Shadow Lugia), 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.
