Pokémon Ruby and Sapphire/Route 119

Route 119 is a wide, grassy area that can only be traveled by foot. As you head north, you'll find trainers.

Pokémon found

 * Feebas: Random Six Tiles, randomly changed whenever the Trendy Phrase is changed. Fairly common on those 6 tiles however.

Trainers

 * Bug Catcher Doug
 * Bug Maniac Taylor
 * Bug Maniac Donald
 * Bug Catcher Greg

Next to Greg is a Super Repel.


 * Bug Maniac Brent

To the east of Brent is a Hyper Potion. Grab it and head north. Go past the house here and run through the grass. Search the trees for Sitrus and Leppa Berries. If you have the Acro Bike, use it to the west to get across the water and collect a Zinc. Return to the main path and go up the steps to the plateau.


 * Pokémon Ranger Catherine

Cross the bridge to the east and to another trainer.


 * Pokémon Ranger Jackson

Head north through the grass to face another one.


 * Bird Keeeper Phil

Grab the Hyper Potion to the northwest of this trainer. Then, search the grass patch to the east to find an Elixir (near the water). As you climb the steps, you'll be surprised by a disguised ninja.


 * Ninja Boy Takashi

When you beat him, move north toward the bridge. A couple of Team Grunts are blocking the bridge, so head inside the Weather Institute.

The Weather Institute
The Institute will offer you rest. Once you enter the door, go to the left to find a bed, and snooze with your party. There's also a PC near the bed, so put a Pokémon away, because the gift of one is coming. Then head over to the other side of the room to tangle Team Aqua/Magma Grunts.

When these jokers go down, head up the stairs. These grunts are after a special weather Pokémon that the Institute has created.

Once the battle is over, a professor gives you the Pokémon Castform (Level 25). Rest again, then leave the Institute and head across the bridge. It's time for a rival battle.

Rival Battle #3
As always, the rival battle will depend on which Pokémon you chose to begin the adventure. Here is a list of Pokémon your rival will use, based on what you picked:

Treecko:

Torchic:

Mudkip:

The fight should be easy, as your Pokémon should be leveled up much higher than your rival's at this point. Just don't be afraid to use items. Your reward for winning, is HM 02 (Fly).

Once you finish the battle, go down to the water to fish, or up towards Fortree City. More Ninjas await.


 * Ninja Boy Yasu
 * Ninja Boy Hideo
 * Ninja Boy Hideo

Once you've beaten the Ninjas, pick the grove of Pomeg Berries. Then head right, into Fortree City.
