What it does
Brick Break is a Fighting-type physical contact move. On hit, it destroys Reflect and Light Screen on the target's side of the field, then deals damage calculated without those screens' damage-reduction multiplier in effect. The wall goes down and the damage lands at full power simultaneously.
Contrast with Defog: Defog clears field conditions too, but it also removes your own team's screens and deals no damage. Brick Break is unilateral — only the opponent's screens are destroyed — and it deals damage on the same action.
In doubles, Reflect and Light Screen protect both of the opponent's Pokémon. When Brick Break removes them, both opposing Pokémon lose the protection in one move — the next turn your team hits both of them at full, unscreened power.
Who runs it
Toucannon (30% usage) is Normal/Flying — Fighting is not STAB for it. Brick Break on Toucannon is coverage, primarily for Rock and Ice-type targets. The wall-removal is a bonus for the 30% of sets that run it.
Morpeko (4% usage) is Electric/Dark — again not Fighting STAB. Brick Break fills a coverage slot against Rock and Normal-type targets. The 4% usage rate reflects this is an occasional pick in specific matchup-oriented team builds.
How to use it
With no screens on the opposing field, Brick Break is straightforward physical coverage — good typing against Rock, Ice, and Normal. The damage output is reasonable at mid-level competition.
Against a dedicated screen team (the Reflect + Light Screen rush is a known archetype), Brick Break becomes immediately impactful. Screens typically go up in turns one and two; from turn three onward the opponent relies on the damage reduction to stay alive. A Brick Break on or after the setup turns removes both screens in a single hit and strips the team's entire defensive advantage. Without screens, the protected Pokémon go back to taking unmitigated damage.
Tips & strategy
Brick Break destroys the opposing team's screens only — it doesn't touch your own. If you've also set up Reflect or Light Screen, they stay up.
If the opponent has both Reflect and Light Screen active, a single Brick Break removes both simultaneously. That's the ideal use case.
Fighting type cannot hit Ghost-type Pokémon — Brick Break doesn't land on Ghost types at all. Any Brick Break user needs backup coverage for Ghost matchups.
Contact move — Rocky Helmet and Rough Skin recoil apply. Minor factor in most cases but worth noting in tight HP scenarios.
