The sixth-generation (Generation VI) of the Pokémon franchise features the addition of 72 fictional species of creatures in Pokémon X and Y to the series. Also included are additions from Pokémon Omega Ruby and Alpha Sapphire. 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.
All Pokémon were created by a team of roughly 20 artists, led by Ken Sugimori and Hironobu Yoshida. For the first time in the franchise, the generation's Legendary Pokémon—specifically Xerneas and Yveltal—were not designed by Sugimori alone; he requested the help of Atsuko Nishida to move their designs forward.
The following list details the 72 Pokémon of Generation VI in order of their National Pokédex—an in-game electronic encyclopedia that provides various information on Pokémon—number. The first Pokémon, Chespin, is number 650 and the last, Volcanion, is number 721. Alternate forms that result in type changes and Mega Evolutions are included for convenience.
Development of Pokémon X and Y began in 2010, and the games were released worldwide on October 12, 2013. Director Junichi Masuda revealed that the three main themes of Pokémon X and Y to be beauty, bonds, and evolution. Beauty was the core focus and Masuda felt France to be a prime example of such; he brought a team to the country for study in 2011. With the games taking place in a region based on France (called Kalos), design inspiration stemmed more from European culture. The legendary trio of Xerneas, Yveltal, and Zygarde have their roots in Norse Mythology, for example. More focus than usual was placed on giving new Pokémon unique elements for this generation.
