DJ Octavio
From Inkipedia, the Splatoon wiki
DJ Octavio is the final boss of Splatoon's Hero Mode.
Appearance
DJ Octavio is a giant octopus, resembling the octopus form of a Octoling rather than the Octarians themselves. He wears an engraved golden helmet, and has a thick green cross scar on one of his tentacles, similarly to the other Octarian bosses. His robot is a gigantic turntable, complete with ink pool, lighting and what appears to be clusters of wasabi or coral. The turntable has four cannons on the front, two extendable fists and a set of thrusters that allow it to stay airborne.
