Not to be confused with the Master Hand laser glitch.
The laser glitch is a glitch that can be performed by Falco, Fox, or Pit in Super Smash Bros. Brawl. It involves causing their projectiles to become stuck in place on the corner of a platform until it disappears. It is performable on New Pork City, Temple, and Corneria, as well as Specialized custom stages.
Performing the glitch
The easiest place to do this is on the breakaway platform on New Pork City. If the player fires left, the laser or arrow will briefly get "stuck" on the corner of the platform. This glitch also works on Temple, near the right side of the stage. There is also a broken platform sticking out of the ground where the lasers will also "stick" on the same stage.
Other players can still be hit by the laser beam while it's stuck.
Falco can do it more easily, because his lasers last much longer.
