While we now have a new human cast with Ash every gen, what also seems important is we always have new rivals every gen that tend to become the driving force of the story each gen:
OS: Gary
AG: Drew/Harley
DP: Paul/Barry, Zoey, etc
BW: Trip, Stephen, Georgia, Burungly
XY: Alan, Shota, Shauna/Miette
SM: Gladion, Kukui, Hau
It's hard to talk about each saga without at least mentioning the rivals and what they did each series because a lot of the plots of each saga tend to revolve around them. What do you think?
