Located to the north of the Pokémon Center, Dewford Hall is known as "Everyone's Information Exchange". Though Dewford is a tiny island community, when someone coins a trendy phrase here, it quickly spreads throughout the region. Speak to the boy outside the building to learn the coolest thing in cool right now; if you disagree, he offers a chance to change the current phrase, which the residents inside will quickly adopt.
Hook the Big One!
Speak to the Fisherman outside the Gym, and answer his question to receive the Old Rod. This low-end fishing rod can hook Pokémon from any body of water, so be sure to try it out everywhere!
Dewford Town Pokémon Gym Leader: Brawly
A big wave in fighting!
The Dewford Gym specializes in Fighting-type Pokémon. Flying- and Psychic-type moves are the most effective here, so this is a great opportunity to train Taillow, Wingull, or Ralts. Keep your Normal-, Rock-, and Dark-type Pokémon out of the fray for now. The Gym is dimly lit when you first enter, but the building lights up bit by bit for each Gym Trainer you defeat. Once the Gym Leader is defeated, the entire Gym lights up completely.
Even with only two Pokémon, Brawly can be a tough opponent. Both his Machop and Makuhita have the Guts Ability, which boosts the Pokémon's Attack by 50% when afflicted by any status condition. Bulk Up allows the user to raise its Attack and Defense, and Machop can deal even more damage by lowering the target's Defense with Leer.
