Having multiples of the same type never stopped Gym Leaders! ... Which seems like an odd strategy to test Trainers with...

Some Kid: "Pfft, a Fire gym? All I need is some water, some ground, and I'm set!"

Also Said Kid: *misues things, gets outplayed despite having a type advantage, and somehow goofs it up because the Gym Leaders use skill and smarts in an RP compared to the games or something*

Some Kid, again: "Wow, r00d! They even said I can't use items! Hacks! Cheating! Railroading! My mom's gonna report them to the League, and then they'll side with ME and I'LL GET THE BADGE YOU DENIED ME!"

The Gym Leader, posessed momentarily by the angry ghosts of angry GMs and DnD DMs alike: *snaps fingers and erases the kid from existence, as Arceus intended*
