The latest “Pokémon Sun and Moon” teaser trailer features the transformation of Greninja to Ash-Greninja during a battle. Can players expect the Ninja Pokémon to appear in their game when the two new titles arrive this November?

The Pokémon Company uploaded the all-new teaser trailer for “Pokémon Sun” and “Pokémon Moon” early Tuesday, and it shows a lot of things that will be part of the Nintendo 3DS-exclusive titles including the middle evolutions of the three Starter Pokémon, the fun adventure in Festival Plaza and the small paradise islands of Poké Pelago. Aside from presenting these new features, however, the trailer also introduced the arrival of Greninja in the Alola region.

For players who are very loyal to the Pokémon franchise, they may already be aware that the bi-pedal Water/Dark-type Pokémon can transform into a special form called Ash-Greninja in the anime series. The unique transformation on the show was due to Ash’s special bond with the Pokémon. Apparently, Game Freak wants “Pokémon Sun and Moon” players to experience Greninja’s special transformation, so it has added the Ninja Pokémon to the games.

According to the official “Pokémon Sun and Moon” website, the Alola region’s Greninja can only become Ash-Greninja through its special Ability called Battle Bond. This bond requires Greninja to attack its opponent until it faints before it can transform into Ash-Greninja. The appearance of Ash-Greninja in the game could be very limited, however, since it reverts back to Greninja when the battle ends. Also, it’s not possible for Ash-Greninja to show up in every battle because it was indicated that the special form would only be triggered by Battle Bond when a battle is quite tough for Greninja.

Compared to an ordinary Greninja, Ash-Greninja’s leg strength is significantly stronger. Because of this, the Pokémon can move up to speeds that are difficult to see using the naked eye. It is very capable of knocking out its opponents easily with its strength and its giant Water Shurikens. Players who are excited to try out Ash-Greninja should watch out for the “Pokémon Sun and Moon” demo that’s arriving on Oct. 18 — exactly a month prior the games’ official release. The special demo will come with Greninja, and players who are successful in transforming the Ninja Pokémon to Ash-Greninja will get the advantage of just transferring the latter to the full version of “Pokémon Sun” and “Pokémon Moon” once they are released.

Meanwhile, another interesting bit that was recently leaked has something to do with the Alola forms of Fox Pokémon Vulpix and Ninetales. took to Twitter early Tuesday to reveal that Spain’s “Pokémon Sun and Moon” website has confirmed the existence of Ice Stone in the games. Fans who saw the tweet quickly concluded that the Ice Stone would likely be needed in order for Alolan Vulpix to evolve to its Ice/Fairy-type evolution called Alolan Ninetales.

In the "Pokémon Sun and Moon" teaser trailer, other special stones could be seen when Isle Aphun is presented. The stones shown in the trailer are Leaf Stone, Dusk Stone, Float Stone and Shiny Stone. This could mean that players will only locate special stones when they explore the small island of Poké Pelago.
