>>45490095most of them don't do anything in the game, the exceptions being korrina and wulfric i guess. the only ones that are memorable are korrina because of the mega evo quest, and maybe clemont if you watched the anime.
beyond that, they're also laughably easy because their teams are shit.
every gym leader after korrina should have had a mega, and the gym battle theme should have seamlessly transitioned into the mega successor theme (
