How to Use Defog

Defeat Crasher Wake to Use Defog

Before you can use Defog, you'll need to defeat Crasher Wake at the Pastoria City Gym first. He specializes in Water Pokemon. We recommend having an Electric type Pokemon like Luxray and a Grass type Pokemon like Roserade in your team before fighting Crasher Wake.

How to Beat Crasher Wake

Use Poketch in Foggy Areas

Pokemon BDSP - Poketch Press the Red Button to Switch Apps
To use Defog, press the R button to open Poketch. If the Poketch app does not appear in the upper right corner of the screen, press the R button twice. If a small screen is displayed, press the R button once to enlarge it.

Once the Poketch app is displayed, press the red button to switch to the Hidden Moves screen and select Defog from the menu.
