USUM is the second game that tackles multidimensions in main story.

The first game to refer to past games plot in the main storyline.

The first game to have THREE legendaries that can evolve, even THREE stage for two of them. Heck type null might even have a third stage

The second game where a legendary can fuse with another legendary ALSO

That legendary still has AN EVEN GREATER FORM

Is something going to happen in the pokeverse that theyre doing something so massive in USUSM?
