Agent 3 (３号 San-Gō,, lit. Number Three?) is the protagonist Inklings of Splatoon 3's single player mode, Hero Mode, and the player's character in multiplayer modes, respectively. They can be male or female, and their hair and eye color may vary, depending on the player's choice of customization.
They are known as "Agent 3" by the New Squidbeak Splatoon in Alterna. This is due to the previous Agent 3 being promoted to Captain of the New Squidbeak Splatoon, leaving the position of Agent 3 open for new recruits.
Agent 3 can have a variety of appearances, depending on the player's choice of style, skin color, eye color, and hairstyle. They wear a new version of the Hero Suit, of which two types, each equipped for different situations, have been confirmed so far. Although having different appearances, both versions of the suit feature a backpack to store the Little Buddy.
This Inkling and their Little Buddy are scrap hunters from the Splatlands, who search for junk gems by day and splat it up in Turf Wars on the side, but got swept up in the New Squidbeak Splatoon and is now their new Agent 3 in the continued fight against the evil Octarians. In Alterna, the new Agent 3 completes various missions to solving the mysteries of Alterna, defeating many Octarians along the way.
