F-Laser (possibly meaning "Firefly-Laser"), known as Will Laser (ウイルレーザー Uiru Rēzā?) in Japan, is the Special Weapon that Mega Man X receives from Izzy Glow in Mega Man X5. In normal fire, X sends out a remote-controlled firefly-like projectile. It is useful for finding something in tight spaces, if it is guided properly. The F-Laser will remain on the screen until it either hits a wall or an enemy, X is hit while controlling the weapon or it leaves the screen. Aside from the actual weapon itself, any moving enemies that make contact with the light trail that the F-Laser leaves behind will take damage. Charged up, X fires a large laser beam.
