This morning, the official Pokemon YouTube account uploaded a trailer for an anime miniseries titled Pokemon Generations.
From September 16th to December 23rd, 2016 there will be 3 to 5 minute episode released every week.
Based on the trailer and the video description, this series will most likely showcase various events seen in the games. An example seen in the trailer is the battle between Green/Blue/Gary and Lance of the Kanto Elite Four. The art style is very reminiscent of the Pokemon Origins Anime mini series that aired in 2013 to promote the release of Pokemon X and Y.
… Which is a very good thing.
Pokemon Origins was a different take on the original adventure set in Pokemon Red/Green/Blue. The anime was more “mature” than the mainstream series with Ash. Red mirrored his namesake in the games, with a robust team and was shown to be a very competent trainer. The music, locales, and many parts of the anime closely resembled the original games (save for one part, but that was to help promote Pokemon X and Y). I highly suggest you guys and girls check out Pokemon Origins, especially if you started playing in the mid 90s.
