I come and go suddenly
Marshadow already?! Da heck?!
What will the other movies be about, then?
I think Necrozma is a pretty good candidate for a movie, especially if they introduce new forms for it; they love to use the anime, movies or main, to advertise new stuff. Of course, they could go the Zygarde route and do it in the main anime, but I think Solgaleo/Lunala and the Ultra Beasts are more likely for that.
I was pretty surprised at the Marshadow reveal as well, as it's the only other event Pokémon besides Magearna. I'm very curious now as to how the rest of gen 7 will be handled. Will it be one of the shortest generations yet or does it have more surprises for us? Personally hope it's the latter.
