How many Pokemon in total are there in X and Y?

There are 69 Pokémon in Pokémon X & Y split amongst three groups: Central Kalos, Costal Kalos and Mountain Kalos. The largest of the three groups is Central Kalos and there are 36 Pokémon in this group. The Costal Kalos group has 18 Pokémon characters and the smallest group is the Mountain Kalos group with only 15 Pokémon including Klefki, the very unique "Key Ring" Pokémon. Some online lists will say there are 70 characters in Pokémon X & Y and their lists will include Diancie, a Rock/Fairy Pokémon, but this character was announced in 2014 and has yet to be added to any Pokédex.

Also included in Pokémon X & Y are "Mega Evolution" characters. These characters evolve in battle when a player is holding the corresponding character-specific Mega Stone. There are 28 Mega Evolution characters which are not included in the 69 new character total as they do not have separate spots within the Pokédexes and evolve from characters from prior versions of Pokémon.
