From New York to Yokohama, an unstoppable wave of yellow monsters is infiltrating public venues, performing strange rituals and targeting young humans. Having already dominated Japan and conquered a number of overseas markets, the “Pocket Monsters” video game series, now in its 20th year, is entering a new realm: reality.

The Blue Samurai, Japan’s national soccer team, will be fighting their way through this year’s FIFA World Cup tournament with the help of one of the world’s most recognizable characters. Adidas announced on Saturday that Pikachu, everyone’s favorite electrifying mouse-like creature, will be joined by 10 other Pokemon to cheer on the boys in blue.
