Christmas (Japanese: クリスマス Christmas) is a winter holiday celebrated throughout the Pokémon world. Much like the secular aspects of the Western holiday in the real world, people wait for Santa Claus to come down their chimneys and deliver gifts and goodwill to them.
In the games
In Generation II, many Pokémon were given away at the New York Pokémon Center as part of the Gotta Catch 'Em All campaign. Each week, a different set of Pokémon were distributed. From December 21 to 27, 2001, the week was Christmas week, and a Delibird with Pay Day (as an Egg) and a Celebi were distributed.
In 2011, to celebrate Christmas, fans could greeting staff members in a certain area of Japanese Pokémon Center stores, and if they did they would receive a small calendar card called the "Happy Calendar" with a unique password included on the back. This password could be input into the Pokémon Global Link to receive a Blissey. This Blissey could then be sent to a Generation V game using Game Sync. The password could be redeemed from November 19 to December 25, 2011.
In 2012, the Pokémon Center Tohoku Victini was distributed to all Generation V games at Pokémon Center stores to Celebrate Christmas. This Victini was available from November 25, 2012 to January 3, 2013.
In 2013, a Scyther holding a Metal Coat and a Haunter without a held item were distributed via trade to players with Pokémon X or Y at Pokémon Center stores and select Toys "R" Us stores across Japan. These Pokémon both had the original Trainer "Christmas" (in Japanese). Since they were both distributed via trade, they would undergo evolution as soon as the player received them. Furthermore, a serial code to obtain a Lucky Egg was also given out at Pokémon Center stores to any players who brought a copy of Pokémon Black or White, Pokémon Black 2 or White 2, or Pokémon X or Y; the serial code could only be redeemed in Pokémon X and Y.
