Deep Cut

Deep Cut is a band in. It is a trio composed of an Octoling named Shiver, an Inkling named Frye, and a manta ray named Big Man.

They are the hosts of Anarchy Splatcast, the news show of Splatsville, and also host Splatfests, with Shiver, Frye, and Big Man each representing one of the three teams in every Splatfest, fulfilling the roles of the Squid Sisters and Off the Hook from previous Splatoon games. During broadcasts, Shiver and Frye take seats on cushions on the ground on the left and face the audience, while Big Man holds a large TV on the right on which news announcements appear, also facing the audience. They can be found in the news studio to the left of the Battle Lobby Tower. In addition to their day job as presenters, they secretly work as bandits to steal treasure, sell it, and split it among the poor while keeping a small amount for themselves.

Return of the Mammalians
Deep Cut appears as antagonists in Return of the Mammalians, warning the New Squidbeak Splatoon that Alterna is theirs to plunder, attempting to intimidate them to no avail before disappearing. Frye, Shiver, and Big Man are thus fought as the bosses of the second, fourth, and sixth sites, respectively. Once each member is defeated, they attempt to escape using a smoke bomb, which always malfunctions and results in sending themselves flying away, revealing a piece of "treasure".

Once all three members are defeated and each piece of treasure is collected, the New Squidbeak Splatoon assemble each of the pieces into a lawnmower-like tool, which the Captain uses to cut up the Fuzzy Ooze surrounding the rocket, getting injured in the process. Due to this, Callie and Marie agree to go ahead with Agent 3, but before they can, Deep Cut appears, once again trying to reclaim the treasure, but to their immense shock, Marie hands it over without a fight. Touched by their generosity, and now feeling guilty about fighting Agent 3 to the death, they ask Marie to be their boss, who reluctantly accepts.

Soon after Agent 3 manages to climb the rocket to fight their enemy, Mr. Grizz, shortly after the latter flies away on his rocket, Deep Cut combine each of their respective powers to propel Agent 3 into space (aside from Big Man, who gives Agent 3 a new set of headphones designed for space). During the mid-point of the battle against Mr. Grizz, Agent 3 gets blasted off of the rocket before getting caught by DJ Octavio's mech. Deep Cut and the Squid Sisters watch from the ground, before Callie yells 'we'll hype you up from here' and Deep Cut and the Squid Sisters collaborate to perform the Calamari Inkantation 3MIX as Agent 3 fights Mr. Grizz with DJ Octavio's help.
