Pokémon Fairy types were the biggest news of the spring and fall, and as you well know, they are now here. It's the first new Pokémon type in four generations, brand new to Pokémon X and Y, and they are quite the gamechanger, aren't they? Or at least the game rebalancer. Now that Pokémon X and Y have been out for a while, let's take a comprehensive look at all the new Fairy-type Pokémon as a prelude to a more academic study of the new creatures.
Pokémon Fairy Type: Strengths And Weaknesses
Fairy type is super effective against Dragon, Fighting, and Dark.
Fairy type is not very effective against Fire, Poison, and Steel.
Fairy type affects all types.
Poison and Steel are super effective against Fairy type.
Fighting, Bug, and Dark are not very effective against Fairy type.
Dragon does not affect Fairy type.
As far as types go, Fairy type has a slightly above average number of strengths and weakness, having three strengths and three offensive weaknesses (i.e. , types it isn't very effective against). And it's weaknesses aren't super common; in fact, one of the reasons Fairy type was added was to balance out Poison type and make it stronger.
Pokémon Fairy Type: Fairy Pokémon List
Now you know what Fairy type can do. Let's take a look at the full list of Fairy Pokémon, via Bulbapedia.
There aren't that many pure Fairy-type Pokémon. Here's the list.
First, retconned Fairy types are quite numerous: Cleffa, Clefairy, Clefable; Togepi; Snubbull, Granbull. Togetic and Togekiss are both Fairy / Flying, of course.
New pure Fairy type Pokémon actually aren't that common: we only have Flabébé, Floette, Florges, Spritzee, Aromatisse, Swirlix, Slurpuff, Sylveon, and Xerneas. That means that, except for Flabébé's evolutions, all the new pure Fairy-type Pokémon were revealed before the game even came out!
Dual-type Fairy Pokémon are only slightly more common.
For older-gen Pokémon, we have: Togetic and Togekiss, as I mentioned. Igglybuff, Jigglypuff, & Wigglytuff are Normal / Fairy. Mime, Jr. & Mr. Mime are Psychic / Fairy. Azurill is Normal / Fairy; Marill & Azumarill are Water / Fairy. Ralts, Kirlia, & the stunning Gardevoir are also Psychic / Fairy (Gallade remains Psychic / Fighting). Mawile is Steel / Fairy. Cottonee & Whimsicott are both Grass / Fairy.
There are only three new dual-type Fairy Pokémon: Dedenne, Carbink, and Klefki. I won't tell you their other types because, hey, you should discover them on your own!
That's the full list of all the Fairy type Pokémon in Pokémon X and Y. As for their moves, their strategies, their Abilities - that's for you to discover.
