Inkling pulls out a large megaphone-like machine and places it on the ground. The machine then emits large damaging sound waves which can be angled. Then, Killer Wail replaces the sound waves with a blast of ink, covering other fighters in it. While somewhat similar to Zero Laser in function, it differs in allowing Inkling to act normally while the Killer Wail is active.
The Killer Wail appears as a special weapon in the original Splatoon. Like all special weapons, it is charged by inking enough ground. When used, it lets out damaging sound waves which damages opponents and passes through walls. Like its appearance in Ultimate, Killer Wail does not cover surfaces in ink, but opponents it does not immediately splat will be covered in ink. In contrast, it cannot be moved at all once deployed.
