Zero Laser

The Zero Laser is Samus's Final Smash in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U. When used, Samus charges up her arm cannon and fires a large beam of energy that travels across the stage, continuously damaging any opponents in its path and dealing high knockback. The blast has a vacuum effect while Samus is charging, drawing in nearby opponents to get caught in it, and the laser can be angled while firing. In Super Smash Bros. Brawl, the beam slowly travels across the screen, while in Super Smash Bros. for Nintendo 3DS / Wii U, it instantly crosses the screen and expands out.

In Super Smash Bros. Brawl, Samus's Power Suit falls apart after using the Zero Laser, leaving her as Zero Suit Samus. Afterward, the pieces of the armor remain on the stage and can be thrown at opponents. In Super Smash Bros. for Nintendo 3DS / Wii U, however, with the removal of in-battle transformations, the Zero Laser does not shatter Samu's suit.
