Ridley unleashes a fearsome roar, and then dashes forward. If he successfully catches anyone, a cutscene will begin. Up to two fighters that were hit with the attack are knocked into the cosmos and land on the side of Samus Aran's Gunship, which takes off in flight. Ridley approaches the Gunship and, with a final roar, fires a devastating beam of plasma energy from his mouth. The beam hits the ship and produces a massive explosion, with Ridley briefly flapping his wings and making a triumphant pose as the attack ends. The resulting explosion causes severe damage to the affected fighters, immediately KOing them if their percentages are at least 100% or else returning them to the stage. After the cutscene ends, the blazing Gunship can be seen crashing into the background.
Meta Ridley in Metroid Prime had a similar attack in the Kinetic Breath Weapon, which is also a red laser beam fired from his mouth. In Nintendo Land, Ridley and Ice Ridley can also fire a straight beam from their mouths. Similarly, the pose that Ridley adopts just prior to firing the beam bears some resemblance to Ridley's pose in the Super Metroid key art.
Samus's Gunships have been significantly damaged or even outright destroyed in Metroid: Zero Mission, Metroid Prime 2: Echoes, and Metroid Fusion. In Zero Mission, Samus is ambushed by Zebesians while leaving Zebes, and her original Gunship is pierced and shot down by a laser from a Space Pirate vessel, causing it to crash back on Zebes. In Echoes (which uses the same ship as seen in Plasma Scream), the ship is damaged by the fluctuating atmosphere of Aether and forced to initiate its auto-repair function for the rest of the game. In Fusion, Samus loses consciousness and her ship drifts into an asteroid belt after the X Parasite that infected her takes over her nervous system. Here, her classic ship is destroyed permanently, but not before she is ejected by an escape pod.
The fact that Ridley tends to attack Samus's Gunship as well as his opponent regardless of whether or not the latter is Samus in the Final Smash may be a reference to his pure hatred of Samus for surviving K-2L.
