Have you caught 'em all?
It's 30 years since a little game called Pocket Monsters launched in Japan - marking the start of a phenomenon that would evolve into a behemoth.
An animated TV series, movies, a trading card game and the mega-hit mobile game Pokémon Go! have all helped to win fans across the globe.
Reportedly the highest-grossing media franchise in history, Pokémon is still a cultural phenomenon today, reaching new generations of fans across the world.
