This is the preview of Pokémon Sun and Moon Anime, and surprisingly Ash defiently looks different, in fact the it appears the animation team appears to have changed!
It may take others to get use to it, but as for me, its growing on me. Animation looks nice and the background still looks good as X&Y. Interesting enough I get a summer vibe looking at it, either this is intentional or not is up in the air.
Now here's one thing I'm really looking forward to, Lillie is in Ash's class (in fact it appears to be a small school with Professor Kukui as the teacher) so it's very likely that the two will become friends and considering her role in the game, we may get a heavy story in the anime than we expected!
