In Super Smash Bros. Melee, anytime during the first 2 frames of activation, powershielding will reflect any projectile, even ones that were already powershielded.

Power Shield (ジャストシールド, Just Shield) (officially called Perfect Shield in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS and Wii U) is a technique where one activates a full shield such that it connects with an incoming attack on the first few frames. Power Shields can also reflect or deflect projectiles depending on where the projectile is perfect shielded. For example, a Charge Shot that is Perfect Shielded near the op of the shield will be deflected at a diagonal angle.

In Super Smash Bros. Ultimate, Perfect Shields are activated upon releasing the shield button the same time an attack hits. Activating a Perfect Shield will cause the fighter to pose and flash white for a brief moment before being able to move. Power Shields in this game no longer reflect projectiles.


  • Power Shield (電源シールド Dengen shīrudo) written as PowerShield in EarthBound Beginnings , is a PSI ability that can only be used by Ninten. But in EarthBound , Ness and Poo's Shield β (Beta) will create a powershield that reflects 50% of damage that was taken.
