Pokémon X and Y/Kalos Coastal Dex

The Coastal Kalos Pokedex indexes all Pokemon around the western parts of Kalos. It contains a total of 153 Pokemon and 82 unique evolutionary lines. Five of the evolutionary lines are exclusive to either version. Only one of the three legendary birds can be caught in the game, the rest requires trading. Due to the great number of version exclusive Pokemon and 3 mutually exclusive legendaries, this regional Pokedex is likely the last one filled.
