A new trailer has been released for "Pokémon Sun" and "Pokémon Moon." The clip teases what lies ahead for those who purchase the games, including new characters, features, and a new form of Pokémon dubbed "Alola form."

So what is Alola form? These are a form of Pokémon found in the Alola region. The trailer only teases one Pokémon in its Alola form — Raticate. The rat-type Pokémon normally looks like a mix between a hamster and a rat. It is brown in color and has large teeth. The Alola form of Raticate, however, looks a little different. It has dark greyish color and has chubby cheeks. Its teeth are similarly huge, but it definitely keeps Raticate's general aura.

It is unknown what other Pokémon will be featured in Alola form. However, The Bitbag has an idea of what Pokémon would work. Bulbasaur, Charmander, and Squirtle would be interesting, for a start. Others include Dragonite and Eevee.

The trailer also features a set of new characters. The game is located in Aether with Lusamine as the head of the Aether Foundation. She is described as "glamorous" and seems like a Pokémon-loving leader. Next up is Faba, the branch chief of Aether. He proceeds to describe Aether Paradise, which is "an artificial island, made entirely by human technology, for the protecting of Pokémon." Wicke is Faba's assistant branch chief. She explains that the Aether Paradise is home to the Pokémon that Team Skull chases after. 

Speaking of Team Skull, its enforcer, Gladion, is also introduced. It would seem that Gladion is the type of character who never backs down from a fight. 

"Pokémon Sun" and "Pokémon Moon" take place 12 hours apart, according to the trailer. "Certain events will play out differently," the clip explains, referring to the two sets. Apart from that, other new Pokémon will also be introduced in the name, including Ultra Beasts.

The two games will be released on Nov. 18.
