Another plot hole is how was zamasu able to travel to the parallel timeline future? why didnt the time rings send him to the future of the current timeline? If he is indeed using the time rings, how did he end up in a future where non of the events happen for him to meet goku?I understand where you're coming from. My whole assumption is based on the fact that he has the time rings and Super Dragonballs so he's able to create his own "timeline" as he sees fit. With those two things in play, he pretty much becomes "God" so to speak. Of course I realize I'm doing some serious reaching here lol. Maybe Zamasu has rewrote the timeline events for his ultimate goal so he had to reset some things so that it can come into fruition.
why does the time machine send trunks to the past of a parallel timeline and not the past of his timeline? Why does it go to trunk's future and not the future of the current timeline?
