>>23253405>>23253446>>23253498Literally no oroof on Gym Leaders and E4 being forced to use monotypes, they are type specialists an therefor they use teams that sum up their abilities with the use of smart movepools and Pikemon type. This acts for sure in the main story and gameplay.
Lance uses draconic species, Lorelei has a marine and Ice tactical team, Bruno symbolizes the toughness and has an Onyx as part of his background, Agatha is explained by the nane pun and reference to Christie, no coincidence she uses common fear related Pokemon with Ghost type moves avaible at time like Astonish, Confuse Ray and such. Flint has a backstory like Volkner and explains his first encounter team. What's the deal with Drapion? Still part of a Bug type line.
Even Whitney 100% will keep her Clefairy/Clefable and maybe Granbull future remakes/game titles, would also add her some coverage since she doesn't use part Flying mons having a cutemons specialization.
Giovanni's Pokemon are not only Ground type but also Field and Monster egg group.
However Glacia really bugs me for one reason, she said she comes from faraway and I doubt there are Hoenn Ice mons there, she could have used at least another region Ice type like Dewgong or Piloswine or Lapras.
