The sixth generation (Generation VI) of the Pokémon franchise features 72 fictional species of creatures introduced to the core video game series in the 2013 Nintendo 3DS games Pokémon X and Y. Some Pokémon in this generation were introduced in animated adaptations of the franchise before X and Y. This generation featured the series' largest graphical overhaul: a shift from two-dimensional sprites to three-dimensional polygons. A new type (Fairy) was introduced for the first time since Gold and Silver in 1999, bringing the total to 18. Greater emphasis was placed on making Pokémon species more unique and in-tune with the culture and fauna of Europe, namely France.
