Zero Laser

The Zero Laser is Samus's Final Smash in every Super Smash Bros. series title since Super Smash Bros. Brawl. 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 she uses the Zero Laser, leaving her as Zero Suit Samus. Pieces of the Power Suit remain on the stage, and can be thrown at opponents. In Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate, because Zero Suit Samus was made a fighter separate from Samus, the Zero Laser does not shatter Samus's suit.

There is a trophy of the Zero Laser in both Super Smash Bros. Brawl and Super Smash Bros. Ultimate. In both games, it can be unlocked by clearing All-Star Mode as Samus.

In Super Smash Bros. Ultimate, Zero Suit Samus has her own variation of Zero Laser as her Final Smash. It starts with her equipping her Power Suit and flying into the background of the stage, firing the laser with a targeting reticle while on her Gunship. After a few seconds, the Zero Laser pauses for a few frames before launching a powerful blast, ending the move.
