Strongest: Cheren I will never forget Work-f***ing-Up in VW2 (which is basically just a harder and "refined" version of W2)...
Weakest: Roxanne Any old Shroomish from Petalburg can completely curbstomp her.
Best Concept: Striaton Brothers A three-in-one gym. I feel enough is said.
Best Gimmick: Viola Surskit and Vivillon actually are surprisingly good anti-fire when it comes to the limited earlygame.
Most Forgettable: Falkner The only thing I consistently remember about him is his underleveled Pidgeotto, not to mention his gym (even in the remakes) had an easily forgettable design.
Dream Gym Leader: Ignoring the obvious dark type or early dragon gym, an early steel-type gym where the fire starter has a clear advantage against the gym leader (no Surskit, either). --- My Current Nuzlocke: http://www.gamefaqs.com/boards/2000300-pokemon-emerald-social/69915984 http://blogsdir.cms.rrcdn.com/100/files/2013/10/waste_time.jpg
Eye'm the Strongest Gym Leader: Probably Cress. Isn't monotype sweepbait like most and can inflict status with Lick (Viola can't even do that). Uses Work Up better than his brothers and Cheren with Panpour's mixed stats and moves (Water Gun > Incinerate).
Best Gym/Type Concept: Cress for not being monotype.
Best Gym-mick: Viola's is gorgeous.
Most Forgettable: Falkner probably.
Ideal First Gym Leader: Cress for being the best. --- XY Maison dialogue: http://tiny.cc/i0ibbx lol: "Pokemon is inherently about the adventure. The adventures are fundamentally different." - zinformant
