What is the best Pokemon in X and Y?

Greninja with Protean is one of the strongest starters in the series. Protean changes its type to match every move it uses, giving it STAB on everything. 122 Speed and 103 Sp. Atk make it a fast sweeper. If you grab Charmander from Sycamore, Mega Charizard Y hits 159 Sp. Atk with Drought boosting Fire moves. Both are S-Tier.

What is the best starter in X and Y?

Froakie . Greninja's Protean ability gives it STAB on every attack type, and 122 Speed outspeeds most of Kalos. Fennekin evolves into Delphox (Fire/Psychic) which has decent Sp. Atk but is slower and less versatile. Chespin into Chesnaught (Grass/Fighting) is the tankiest but takes super effective hits from common types like Flying and the new Fairy.

What is Fairy type and how does it change the tier list?

Fairy is a new type introduced in Gen 6. It's super effective against Dragon, Fighting, and Dark, and completely immune to Dragon moves. This nerfs Dragon-types that dominated every previous generation and boosts Pokemon that gained Fairy typing. Gardevoir goes from Psychic to Psychic/Fairy. Mawile becomes Steel/Fairy with a Mega form. New Pokemon like Sylveon are pure Fairy with strong Sp. Def.

Which version exclusives are better, X or Y?

X gets Xerneas (pure Fairy, Geomancy is broken) and Y gets Yveltal (Dark/Flying, Oblivion Wing heals). Xerneas is the better pick — one Geomancy boost doubles its Sp. Atk, Sp. Def, and Speed, making it one of the most overpowered legendaries in the series. For Mega Evolutions, X gets Mega Charizard X (Dragon/Fire) and Y gets Mega Charizard Y (Fire/Flying with Drought).

What's the best team for an X and Y playthrough?

Greninja (starter), Mega Charizard from Sycamore's Charmander, Aegislash from Honedge on Route 6, Gardevoir from Ralts on Route 4, Lucario from the Mega Evolution event in Shalour City, and Sylveon from Eevee with high Affection plus a Fairy move. Strong mix of new Fairy types and Mega powerhouses.

How do Mega Evolutions work in X and Y?

A Pokemon holds a Mega Stone and Mega Evolves during battle once per fight. Its stats jump, it may change type, and it gets a new ability. You only get one Mega per battle, so your Mega Stone holder is your team's ace. Mega Lucario is given to you during the story, and Sycamore's starter comes with its Mega Stone. Pick your Mega carefully since it shapes your whole team strategy.

Is Aegislash good in X and Y?

Aegislash is one of the best Pokemon in Gen 6. Steel/Ghost typing gives it three immunities (Normal, Fighting, Poison) and Stance Change lets it swap between a 150 Def/Sp. Def shield form and a 150 Atk/Sp. Atk blade form. King's Shield switches it back to defense and punishes contact moves. It's so strong it got banned to Ubers in competitive. Honedge shows up on Route 6 early in Kalos.

Pokemon X and Y Tier List - Best Kalos Pokemon Ranked

X and Y introduced Fairy type and Mega Evolution in the same game, and both reshape the tier list. Dragons aren't untouchable anymore since Fairy resists Dragon and hits it super effectively. Gardevoir gains Fairy typing and a Mega form with 165 Sp. Atk. Greninja is the standout new starter with Protean turning every move into STAB. Professor Sycamore also hands you a free Gen 1 starter, and Mega Charizard is one of the strongest picks in the game. Both new Kalos Pokemon and older ones available during the main story factor into the rankings.
