dj_octavio
Main antagonist of Splatoon (series). Named DJ Takowasa in the Japanese version.
The leader of the Octarian (enemy)s, Octavio rides around in a electronic music-themed flying fortress while using turntables to attack. He is a very loud and boisterous character. In the American English version, he tends to make EDM-related puns while attacking.
He wears a golden octopus-shaped kabuto (helmet) on his head.
According to a Sunken Sea Scroll (post #2116111), Octavio used to be friends with a younger Cap'n Cuttlefish.
