The grunts have some pretty easy Pokémon between levels 14-16, so these battles should not prove to be a challenge. Once you win, the team boss Archie (AS) or Maxie (OR) will show up immediately after the battle and take the grunts back with them.

Then you’ll deliver the Devon Parts to Captain Stern, completing the quest.

With this portion of the main story done, you can continue towards Mauville City and the third badge.
