Cap'n Cuttlefish has brown eyes, the Cap of Legend, denim shorts and wears a robe that has medals, as he was the leader of the Squidbeak Splatoon during the Great Turf Wars. He also has holes in his brown shoes that expose his toes.
Cap'n Cuttlefish was recognized as a hero during the Great Turf War. Now he watches over Octo Valley, watching for any suspicious behavior.
His favorite food is crab cakes (biscuits in the European version) as pointed out by Agents 1 and 2. He is often distracted by them, which prompted DJ Octavio to escape his snow globe prison.
Long before the first game's events, Cap'n Cuttlefish served as the leader of the Squidbeak Splatoon, where he helped the Inklings defend themselves from the Octarians. In the end, the Inklings won the Great Turf War and the Octarians resorted to hiding underground.
Years later, the Octarians steal the Great Zapfish in order to use it for their power supply, and as revenge. Cap'n Cuttlefish later recruits a random Inkling to bring it back. Much later, Cap'n Cuttlefish is captured by the Octarians' leader, DJ Octavio. With Agents 1 and 2, Agent 3 went to face off DJ Octavio to rescue both the Great Zapfish and Cap'n Cuttlefish.
Two years after the first Splatoon, initially, he was only mentioned in a Sunken Scroll. Later, he made his full appearance as an NPC, where he assists Agent 8, along with Pearl and Marina to get back onto the surface.
