>gen !
Copycat. There aren't many other NPCs from that gen who could return that aren't PC/gym leader/E4/champion.
>gen II
Kurt or his granddaughter. Just so we can unlimited special balls.
>gen III
Winona. Gets heavily overshadowed by Falkner and especially Skyla, so giving her a little more personality would be nice.
>gen IV
Thorton. It's that Frontier Brain. Because why not?
>gen V
N.
>gen VI
Emma.
>gen VII
Hau, so we have a returning rival.
Tried to go for different types of roles and not too many characters from the same gender.
