Marina

Marina (イイダ Iida) is the shy yet highly intelligent teal member of the pop idol duo Off the Hook and an unofficial Agent of the New Squidbeak Splatoon and the granddaughter of King DJ Octavio. Despite being an Octoling, she lives above ground in Inkopolis alongside her best friend and partner, Pearl White. She plays a major role in Inkling Uprising, being a major focus in Arc III and the main focus of Arc IV. Unlike her grandfather, Marina wishes for peace between Inklings and Octolings.

Marina grew up in the Octarian domes and was born into a middle class family. She spent lots of time with music and machinery, eventually becoming a master of both herself. Like many Octolings, Marina was forced into the military and served the Octarian Army until an incident shortly after Agent 3's recovering of the Great Zapfish. When not under the effects of Mental Corruption, which Marina discovered but didn't tell anyone out of fear, she would sneak up to the surface from time to time to talk with Pearl, who had found her one day while Marina was curiously exploring. After the aforementioned incident, Pearl found Marina passed out and restored her back to health. Marina has held Pearl is high respect since.

During Great Turf War II, Marina joined the NSS alongside Pearl, suspecting Octavio was returning, and later the Octarian Resistance. She aided Abigail Takoika and Smith Powers in creating machines.
