A new trailer was released for "Pokémon Sun" and "Pokémon Moon" previously and it highlights the final evolution stage of the three starter Pokémon. Also, more creatures were revealed for the latest installments and they are actually the guardians of the Alola region.

It was revealed in the new promotional teaser for the latest Pokémon games that Rowlet can evolve into Decidueye. The creature is described as "the arrow quill Pokémon," and it is actually a ghost type and a grass type at the same time. Decidueye can be hard to defeat since its speed is unmatched and it can grab arrow quills from its wings then shoots these towards its opponents.

According to a report from GameSpot, the final evolution of Litten is Incineroar, and the Pokémon becomes a dark type and a fire type. Incineroar is labeled as "the heel Pokémon," and its strength is raised once the fighting spirit of the creature grows stronger. It can produce fire from its waistline when the Pokémon is really pumped up and the flames around its hips have a similar appearance to a championship belt. It can unleash a very powerful move called Darkest Lariat and it is the only one capable of learning that attack.

Meanwhile, Popplio transforms to a very gorgeous Pokémon called Primarina. It is described as "the soloist Pokémon," and it is a creature that is fond of dancing. While it dances, it summons balloons of water that can be controlled via the sound waves that come from its voice. Those balloons can also be used as a weapon towards its opponents. Primarina is the only Pokémon that can learn the deadly attack called Sparkling Aria.

Aside from the three new evolutions that were revealed, the Alola guardian deity Pokémon were also introduced in the trailer. They are Tapu Lele, Tapu Bulu and Tapu Fini, and they have a similar Z-Move called "Guardian of Alola" which creates a giant being that's capable of smashing its enemies without a sweat. The effect of the attack is that it will reduce 75 percent of the opponent's current health.
