Zero Laser

In earlier stages of Super Smash Flash 2's development, Zero Laser from Super Smash Bros. Brawl was to be Samus' Final Smash. The attack would have worked in an identical fashion to its Brawl counterpart and would destroy Samus' armor, forcing you to play as Zero Suit Samus. The attack has since been replaced with Hyper Beam, an attack from Super Metroid.
