A list of the Pokémon from the games Pokémon X and Y. This game introduced the fewest Pokémon of any generation with a mere 72, more than half of which were revealed pre-release. All were unrelated to Pokémon of previous generations, with the exception of new Eeveelution Sylveon. The size of the generation was compensated for with 48 different Mega Evolutions (plus two Primal Reversions) for older Pokémon, as well as the Kalos Pokédex being the absolute largest yet at 457 total.
