The June 2013 issue of CoroCoro Comics has leaked, and revealed four new Pokémon. Several other new features, such as riding Pokémon, are also featured in the article.
The new Pokémon are Yanchamu (ヤンチャム), Yayakoma (ヤヤコマ), Erikiteru (エリキテル), and Gōgōto (ゴーゴート).
The new moves revealed are 「すてゼリフ」 Parting Remark, which decreases the opponent's stats, and 「パラボラチャージ」 Parabola Charge.
The new region is called Karosu (カロス地方) and it is shaped like a five-pointed star. Miare City (ミアレシティ) is located at the center of the region. The symbol of Miare City is the tall tower in its center. Miare City appears to be the city seen in the original trailer. Miare City is so big that players ride Gōgōto in it to traverse it; players can direct Gōgōto with its horns.
The new Pokédex is shown, and it is card-shaped and has a holographic center that is visible when the two ends are separated.
There are now three slightly different characters of each gender to choose from. Text boxes are now of variable size. Images indicate that the player can now walk diagonally.
