Pokémon That Can Learn Flash: A Comprehensive Guide

Flash, a non-damaging Normal-type move introduced in Generation I, has been a staple in the Pokémon world, both in and out of battle. This article delves into the intricacies of Flash, exploring its effects, its utility, and, most importantly, which Pokémon can learn it.

What is Flash?

Flash (Japanese: フラッシュ Flash) is a move that decreases the target's accuracy stat by one stage. Beyond its combat application, Flash possesses a unique overworld function: illuminating dark caves.

Flash in the Overworld

In the earlier generations, Flash was crucial for navigating dark caves. When used from the party screen, it would light up the surroundings, allowing players to progress. The effect persisted even when moving between different areas within the cave. However, its overworld utility has evolved across different generations.

Generation I: If used outside of a dark cave, the message "A blinding Flash lights the area!" would appear, despite having no actual effect.
Pokémon X and Y: With the absence of dark caves, Flash instead caused the screen to zoom out, revealing more of the surrounding area.
Pokémon Omega Ruby and Alpha Sapphire: Dark areas returned, allowing Flash to light up the surroundings once more. However, it was no longer usable outside of battle.
Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!: Flash retained its battle effect of decreasing accuracy.

Flash in Battle

In Generations 1 to 3, Flash had a 70% accuracy and decreased the target’s accuracy by one stage.

Z-Flash

In Generation 7 onwards, when a Pokémon holds a Normalium Z and uses Z-Power, Flash transforms into Z-Flash. This enhanced version not only lowers the target's accuracy but also raises the user's Evasiveness by one stage.
