Just ahead of E3 2017, Nintendo announced plans to release Pokemon Ultra Sun and Pokemon Ultra Moon before the end of the year. Now, a new teaser released via the Japanese Pokemon website seems to hint at an appearance from a particularly mysterious type of pocket monster.

Unown is a psychic-type Pokemon that was first introduced to the series in Generation II. These creatures comprise a kind of ancient alphabet that was central to a memorable quest from Gold and Silver, where players needed to complete a separate Pokedex in order to generate and print Alph Ruins Stamps.

The new teaser uploaded by Nintendo features messages written in Unown script prominently. It's not completely clear what role these creatures will play in the game's plot, but since we already know that Ultra Sun and Moon will feature an expanded selection of Pokemon, it seems very likely that it'll be possible to capture Unown.

In fact, Nintendo has already teased the idea of Unown playing a role in Ultra Sun and Moon. During the livestream where the games were announced, the company also confirmed that Gold and Silver would be hitting the Nintendo 3DS Virtual Console service — and the trailer for the re-release featured Sun and Moon written in Unown script.

It will certainly be interesting to see whether there are more links between the sequels to Sun and Moon and the retro re-release of Gold and Silver. Pokemon fans certainly have a lot to look forward to in the latter part of 2017.

At the time that Ultra Sun and Moon were announced, many were disappointed that Nintendo wasn't working on a version of the games for the Switch. However, it seems more and more like the follow-ups are a fully fledged sequel, rather than the traditional third entry, which is great news for players who want to see a little more of Alola.

Pokemon Ultra Sun and Pokemon Ultra Moon are scheduled to release for the Nintendo 3DS on November 17, 2017.
