Pokémon Ultra Sun and Ultra Moon are creeping ever closer, and are likely to be key in driving 3DS and 2DS sales into the Holiday season. The Pokémon Company, aware that time is ticking away, is gradually ramping up with details on what these new entries will bring to the Alola setting.

Fresh on YouTube now is a new trailer that showcases mostly aesthetic things - we get more looks at the overworld, hints at the mysteries to come and it also pitches new avatar customisations and the previously confirmed Rockruff evolution.

The official website and a press release also go into some high-level plot details, in addition to outlining the 'Z-Power Rings'.

In Pokémon Sun and Pokémon Moon, the story centered heavily around the Legendary Pokémon Solgaleo and Lunala. In Pokémon Ultra Sun and Pokémon Ultra Moon, a new story unfolds featuring Necrozma alongside the Legendary duo.

Ominous dark clouds begin to spread and the secrets of Necrozma and the Alola region, which were never disclosed in the previous games, will finally come to light.

The main characters that appear in Pokémon Ultra Sun and Pokémon Ultra Moon will feature brand new styles. Players can pick their appearance at the beginning of the game and choose either Rowlet, Litten or Popplio to begin their as-yet-unknown adventure in style. Also discovered in the story is a new Z-Power Ring which players will acquire in the game and can activate to use an even wider variety of Z-Moves. A physical toy of the new Z-Power Ring will be available at launch to purchase and interacts with the video games.
