>>50997034Really...Ultra Space is a serious waste of potential when you think about it for longer than five seconds. It's the means to traverse space and time throughout not only this universe but other universes as well, including encountering legendaries from other worlds and unique pokemon never seen before like the Ultra Beasts.
Given Ash is the champion of Alola and holds jurisdiction over it, plus the Ultra Guardian bullshit it would make perfect sense for him to end up scouting in Ultra Space after JN when UBs invade just to end up getting lost in spacetime and having to work his way back home. Cue the different gens Post-JN.
They wouldn't have to leave the possibility of a "Dr. Sam Becket never returned home." ending. Just have the new series have that plotline but Ash finds his way back to his original world. He'd have gained the experience and knowhow to then just freely traverse different worlds like new regions and return home when he wants.
