What region was introduced in Pokémon X and Y?

Kalos was the region introduced in Pokémon X and Y.

The sixth-generation games were released worldwide for the Nintendo 3DS on October 12, 2013. Kalos is inspired by France, and its central city, Lumiose City, is modeled partly on Paris.

The region's geography and architecture helped give Generation VI a distinctly European setting. Its legendary Pokémon are Xerneas and Yveltal, whose designs reflect the games' themes of life and destruction.

Kalos is sometimes confused with Hoenn, which debuted in Pokémon Ruby and Sapphire, or Unova, which debuted in Pokémon Black and White. Pokémon X and Y also marked the main series' first worldwide simultaneous release and introduced fully polygonal 3D environments and character models.
