The Kalos Pokedex from X and Y spans 721 Pokemon with two new additions that change the math: Fairy type and Mega Evolution. Fairy type hard-counters Dragon for the first time. Mega forms like Mega Charizard and Mega Gardevoir push mid-tier Pokemon into new territory. Professor Sycamore hands you a Gen 1 starter early. Filter by type to see how Fairy reshuffles the chart.

721 total across six generations. Gen 6 added 72 new species (the fewest of any generation). The Kalos regional dex is split into three sub-dexes: Central, Coastal, and Mountain, each covering different areas.
Mega Evolution is a temporary battle transformation available to certain Pokemon when they hold a Mega Stone. It boosts stats (usually by 100 BST), sometimes changes typing or ability, and lasts for the rest of the battle. Only one Pokemon per team can Mega Evolve. Charizard, Gardevoir, and Lucario are notable Mega users.
Fairy type was introduced in Gen 6 as a counter to Dragon, which had been too strong for years. Fairy is immune to Dragon moves, super effective against Dragon, Dark, and Fighting, and weak to Poison and Steel. Existing Pokemon like Gardevoir, Jigglypuff, and Marill were retroactively given the Fairy type.
Generation 6, released in 2013 worldwide for the Nintendo 3DS. First mainline games with 3D graphics, first global simultaneous launch, and introduced Fairy type, Mega Evolution, and Pokemon-Amie.
Yes. After the first gym, Professor Sycamore offers you Bulbasaur, Charmander, or Squirtle. Each one comes with its Mega Stone. Mega Charizard (X or Y form) is one of the most popular picks in the game.
