The first Pokémon games - Red and Green - were introduced in Japan on February 27, 1996, immediately taking the world by storm. With a roster of 151 pocket monsters, the franchise started with a steep, but manageable, learning curve. When Generation II came around, the Pokédex had 100 new entries; an impressive addition, but still not overwhelming. Another 100+ were added in Generation III, and again in Generation IV. Fast-forward to two decades after the world met Pikachu, and there are over 800 Pokémon across seven generations.
Fans of the gaming franchise number in the hundreds of millions, and they prove their loyalty by crafting fan theories and creating Pokémon art. Yet even the most die-hard among them might not fully grasp the complete history of the Pokémon Universe, which is extensive (and not always logical).
Between all of the games, movies, and the TV show, the Pokémon Universe has slowly but surely filled out its entire history, from the creation of the universe to contemporary Pokémon training.
