Not if they all come from the same planet and have (or acquire) the same power. That's science fiction, pure and simple, even if the power is fantasy-like.
But suppose they come from many planets, and have different powers. . . arriving on earth for whatever common reason or somehow for different ones. . . . can that qualify as a metaorigin? Perhaps if the powers get more emphasis than the origin. . .
I ponder philosophically,. And my muse, fortunately, ignores it, preferring an all-human cast.
