The Zero Laser is Samus' Final Smash. Samus charges her arm cannon and fires a large beam of energy that deals a high amount of damage. After firing the beam, Samus' Power Suit is "damaged" and falls off of Samus' body, transforming her into Zero Suit Samus.
After the beam has been fired and the Power Suit removed, the damaged pieces of the suit can be picked up and thrown as items by any player. The items have very high knockback and decent damage, but they also can be picked up and thrown at ZSS.
In a posted video, it shows Samus using her Final Smash. It lasts about a total of 4 seconds. The move's damage varies from source, but depending on the time the opponent remains in the laser, it can do from 40-78% damage. While not a One-hit KO, if used near the edge of a stage the laser can push opponents past the blast line.
While Samus is using the attack, all nearby enemies behind her (as well as some items) will be pulled toward her and into the line of fire, if close enough. Also if enemies fall on top of the laser they too will be pulled into the attack.
The Zero Laser can also be angled slightly up or slightly down by tilting the control stick in the desired direction, though this does not have much of an effect on the laser's area of effect and cannot be moved above approximately a 30 degree angle.
The transformation into Zero Suit Samus takes quite a while, and thus is easily punished. Even if you manage to KO everyone, there's usually enough time for that player to come back to life and get into position to attack just as the transformation finishes. So it may be better to fire it far from the ground, making the opponents harder to punish her.
Finishing the Final Smash in mid-air does not put Samus (or rather, Zero Suit Samus) into a Helpless state, however she will fall for quite some time until all her suit pieces fall off. If she is not above a platform, this is enough to KO her on most stages other than New Pork City or Temple.
Since the move doesn't engulf the entire screen and only a horizontal strip, some prefer to jump and then use the Zero Laser to maximize its area of effect. The reasoning behind this is that a shot fired on the ground will KO characters who are standing on the ground, but a shot that's fired a little bit above the ground will KO characters who are on the ground and characters who are a little bit higher.
As demonstrated in the Tokyo vs Kyoto match, Zero Laser's effect was slightly changed; it lasted 2 seconds longer than usual.
The move is unique to Brawl. Originally, Samus's Power Suit is lost in a crash after her starship is shot down in Metroid Zero Mission. However, rival bounty hunter Gandrayda can use a move nearly identical to the Zero Laser when mimicking Samus's form in Metroid Prime 3. Also in Metroid Prime 3, Samus could transform into a Phazon form, during which she uses a move strikingly similar to the Zero Laser, though this beam actually consists of two beams intertwined and rapidly fires streams of Phazon beams instead of one massive beam.
- A glitch can be performed with this Final Smash that makes it so Samus doesn't transform to Zero Suit Samus. Performing it is the same as performing the Puff Up, Diffusion Beam, and Golden Glitches: play on Bridge of Eldin (or any stage with reforming terrain) when the destroyed bridge middle is repairing itself, go between the ledges, activate the final smash, and then when the bridge is whole again, Samus will pop back onto the bridge without transforming.
- It should also be noted that Pit's Mirror Shield, pointed upwards, can negate all but the final blast of the Final Smash. Whether this is a glitch or not is unknown.
Samus's Final Smash. The beam emerging from her Arm Cannon is dreadfully powerful and causes great damage to enemies. The beam travels slowly but can be swept up and down. The recoil of the beam is so great that it tears off her Power Suit, revealing Zero Suit Samus. The pieces of her armor can be picked up and thrown as weapons.
