The Pokemon franchise has now visited eight regions so far, from Kanto in Gen 1 to Galar in the new Gen 8. And now, we are getting a new Pokemon anime titled Pocket Monster, and it will feature all eight regions. They even released a new video:
The video re-introduced the starter Pokemon from each region, which teased that they may have a big role. Unfortunately, the teaser did not reveal any further details so far.
However, the video did say that they will reveal more about this new Pocket Monster anime during the 29th September episode of the Pokemon Sun and Moon TV anime. As of now, we would just have to wait for that date, though fans are already speculating what Pocket Monsters will be about.
