Effects

Flash lowers the target's Accuracy by one stage.

Stats can be lowered to a minimum of -6 stages each. Pokémon with the abilities Keen Eye, Clear Body or White Smoke cannot have their accuracy reduced.

Changes

In Generations 1-3, Flash has 70% accuracy.

Outside of battle

Flash lights up dark caves. In the original games dark caves made the screen almost completely black, whereas in later games you can always see a very short distance around you; Flash merely expands that circle. In the games it is an HM, it can only be used with the appropriate Gym Badge.

Z-Move effects

When a Pokémon is holding Normalium Z and uses its Z-Power, Flash turns into Z-Flash and raises Evasiveness one stage, in addition to its usual effect as above.

Move target

Targets a single adjacent Pokemon.
