Don't forget Magearna
Yep, its looking likely that Magearna will appear in SM116. This now leaves Kartana and Melmetal as the only Gen 7 Pokemon that have yet to debut in the anime.Judging by SM116's title, we may see Magearna in the anime.
Kartana has still yet to appear, but it's an Ultra Beast.It's crazy all legendaries + mythicals of gen 7 appeared in the Sun & Moon anime.
EDIT: There's Melmetal left but I think it's safe to say it will debut sooner than later, before the end of SM.
Kartana debuts in episode 124. Melmetal is the last Gen 7 Pokemon to debut
There's no guarantee of that.Good because Ash's will evolve
I think that this thread should now be locked, because there's no more Alolan Pokemon left to debut.
