>>38149182>>38149185Guess you never extensively watched DP anime, huh?
Aaron, Bertha, Flint, and Lucian. Flint should be the most obvious of the four since he had a role in the story, appeared the most in the anime, is Volkner's counterpart, and had an infamously non-Fire team in DP. (Yeah, Bertha and Aaron also had Pokemon outside their specialty in DP, but it was only one, not three.)
Bertha should be the next obvious because she has a connection to Agatha from the original E4. In the anime, Bertha also told Ash to be more observant in battle, something that he never quite picked up on after DP.
>>38149263>Alola>Who cares?Alola had the most prominent E4 to date; all of them had some role in the story.
Hala and Olivia were their island's Kahuna and game boss. Acerola was present for most of Ula'Ula Island. Molayne was present for the observatory challenge and one of the few people you had to fight in SM to get their type's Z-Crystal. And Kahili was present when you get Flyinium Z in USUM (yeah, she wasn't there for the story in SM, but it made sense as she had an occupation outside of Pokemon.)
