All the members of Xavier Academy, a group of funny little people living a peaceful life.
The setting background time is based on the movie timeline of Cha Hanzi, which is around 1983, which is about ten years after the reversal, the year when the apocalypse began. The Avengers involved are also in the movie timeline, after Avengers 2, after the Ultron incident occurred. (Although Captain America III is good-looking, it is too sad.) In the HP world, the timeline of Fantastic Beasts and Where to Find Them will probably not be moved, and the timeline of Harry Potter will be advanced to the Goblet of Fire period.
