The Poncho Pikachu Gallery
Between December 2014 and June 2017, Japan's Pokémon Centers ran the most charming promotion in the card game's history: Pikachu, dressed in ponchos. Every card in the line was drawn by Kouki Saitou, every one was a Japanese Pokémon Center exclusive, and none was ever released in English. They were never in booster packs. You got them by standing in a particular store, on a particular day, doing a particular thing: attending an opening, joining a campaign, earning play points, or buying a box built around the card itself.
The wardrobe below is the complete Pikachu line, in release order. Two of its members carry a different printed name, Mega Tokyo's Pikachu, but wear the Mega Charizard Y poncho that started everything; the seven between them are literally named Poncho-wearing Pikachu. The count page in this shelf shows the arithmetic, and the boxes page opens the packaging.
