Quick Guard protects all Pokémon on the user's side of the field from moves that have increased priority during that turn, such as Quick Attack or Aqua Jet. It does not block moves that have been given an increased priority through Prankster that would not usually have one.
This move has +3 priority, so it will be executed before most other moves.
Feint and Shadow Force lift the effect of Quick Guard from the opponent's team when successfully used on an opponent, and Feint hits despite being an increased priority move. When used on an ally, Feint is blocked by Quick Guard.
Hyperspace Fury, Hyperspace Hole, and Phantom Force will lift the effect of Quick Guard from the target's team when used successfully. Feint and Shadow Force now lift the effect of Quick Guard from all allies, if they hit an ally.
If powered up by a Fightinium Z into Z-Quick Guard, the user's Defense stat rises by one stage.
Mienfoo jumps into the air and puts its hands together in front of it with its palms touching. Its body then becomes outlined in a red outline, then it puts its arms forward. A pulsating bright red energy shield appear in front of Mienfoo's hands and goes around itself and others, protecting them from attacks. While the barrier is up, Mienfoo floats in the air.
