Is Pokemon Sun and Moon's story new or a continuation? Okay, I just saw lately the new Pokemon Sun and Moon anime series. I guess you're already familiar with the characters. In the new series, Ash's design is different from what we all know spiky black hair (etc). 

Is the Sun and Moon series a new different pokemon story (like Red's series or a story of an alternate world) because the Ash looks different or it's another continuation where Ash just changed his look?
Firstly, there is a drastic change in art style compared to the XY&amp;Z series. Also, Ash is depicted more as a comedic character compared to his character in XY&amp;Z. One interesting factor to note here is that unlike all the other series before, anything related to Kalos or Ash's adventure there hasn't been mentioned even once.

However, based on Pikachu's move set, we know for sure that it's post Unova. And another interesting thing to note is during the episode where the characters visit Kanto, during the battle between Brock and Kiawe. Ash had prior knowledge on Mega evolutions while the rest of the characters didn't know what it was. Ash came to know of the same during his time in Kalos.

I guess it's up to to the writers to decide based on how they want to continue the series in the future.
