Pokémon Ruby and Sapphire/Route 127

Trainers
In Pokémon Ruby and Sapphire, Route 127 is a super-wide seaway with lots of trainers bobbing about. In west side of the passage is a Zinc. Just a short distance southwest is the entrance to Route 126.
 * Bird Keeper Byron

Just southwest of this fight is the entrance to Route 126. Head across the water to the east and loop under the long, vertical island here to find a large, horizontal island. On the north, east and south reefs, you'll discover trainers. Remember, anywhere you see a dark place while Surfing can be explore with Dive.

 * Fisherman Jonah


 * Fisherman Henry

When you are done, head south until you reach another sandy island. En route, you'll discover one trainer, and another on the beach.

 * Black Belt Koji

Off the northeast corner of this island is a circular dive spot. Dive and surface at the other side, then explore the area to find a small island. Here, you'll find Carbos. Once you have it, go back through the underwater passage and return to the main sea, and head south. One trainer remains.
