"We're on duty today, whether you like it or not. Can't sleep while the enemy plots!"

Agents 1 and 2 are generally busy with their own problems these days, so these guardians of order protect the denizens of Inkopolis from the shadows.

— Cap'n Cuttlefish & Agent 3 reason for joining Team Order

The new Squidbeak Splatoon Captain, Agent 3, standing besides the Squid Sisters, Callie and Marie.

Agent 3 (3号 San-Gō , lit. Number Three?) is the protagonist Inklings of Splatoon and 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.

As they are the Inkling who joins Cap'n Cuttlefish's New Squidbeak Splatoon to rescue the Zapfish, they are known as "Agent 3", as the other two Agents are the Squid Sisters, Callie and Marie (who are Agents 1 and 2 respectively).

In Splatoon 2, Agent 3 is away with Cap'n Cuttlefish, so another Inkling, the protagonist "Agent 4", follows Marie to find her missing cousin Callie and stop another Octarian theft of the Great Zapfish. In Splatoon 3, the original Agent 3 is named as the Captain of the New Squidbeak Splatoon, replacing Cuttlefish.


Agent 3 can have a variety of appearances, depending on the player's choice of gender, skin color, and eye color, as well as their current ink color. They wear the Hero Suit, and can pick up armor to wear as well. They wield the Hero Shot by default, but can use a Charger or Roller for amiibo challenges.



Not much is known about Agent 3's background, except that they are at least 14 years old, since they have complete control over their squid and humanoid forms.

Agent 3 initially went to Inkopolis for an unknown reason, but got swept up in Cap'n Cuttlefish's quest to save the Great Zapfish. In Octo Valley, Agent 3 completes various missions to retrieve stolen Zapfish, defeating many Octarians along the way. Eventually, Agent 3 confronts DJ Octavio, rescuing the Great Zapfish and restoring Inkopolis' power supply.

Splatoon 2

Octo Expansion

Agent 3 returns in Splatoon 2's Octo Expansion. Agent 3 retains their original Hero Suit, now also wearing a gray torn cape with a number "3" in Inklish.

Before the start of the DLC, Agent 3 and Cap'n Cuttlefish continued exploring Octo Valley when they ended up in battle against a young Octoling. However, an unknown third party attacked them, leaving them stranded in the Deepsea Metro, with Agent 3 separated. Cuttlefish and the Octoling nicknamed Agent 8 teamed up to collect the four thangs and escape the Deepsea Metro.

Once Agent 8 collected three of the thangs, Cap'n Cuttlefish made a "missing" poster for Agent 3, which allows the player to determine Agent 3's gender, skin color, and eye color.

After Agent 8 collected all four thangs, the Telephone built them into a blender and tricked Agent 8 and Cuttlefish inside. However, Marina used Agent 8's CQ-80 device to unleash a distress signal to which Agent 3 responded by jumping through the roof and destroying the blender. They were rendered unconscious as a result, with Cuttlefish staying behind to look after them as Agent 8 escaped through the hole Agent 3 made.

While Agent 8 was away, the Telephone attacked Agent 3, partially sanitizing them. Under the Telephone's control, they tied up Cuttlefish and later attacked Agent 8 before they could escape to the surface. After being defeated, the sanitization disappeared, leaving them once again unconscious. They eventually woke up after Agent 8 and Off the Hook defeated the NILS Statue, used by Telephone, as Commander Tartar, to destroy Inkopolis, now with a band-aid on the back of their head as the credits rolled.

When Agent 8 returned to the Deepsea Metro, Cuttlefish explained that Agent 3 went back on patrol.

Inner Agent 3

Main article: Inner Agent 3

After Agent 8 completed all the tests, a locker in the Central Station opened and they had a flashback to the first time they heard the Calamari Inkantation, prompting a final battle against their "Inner Agent 3".

Splatoon 3

Sometime before the start of Splatoon 3, the original Agent 3 was promoted to the captain of the New Squidbeak Splatoon, with Cap'n Cuttlefish stepping down and going into retirement. It appears that the player can customize them, like in the Octo Expansion.

Art Book's Information

Whether Eight’s remaining memories, something from Agent 3, or an image of the telephone’s prediction of Agent 3’s future, these puzzling memories come to hand. “They’ve got a cape.” These power words make one feel the darkness, though it may just be us. Ink tank

As the third member of the New Squidbeak Splatoon, they’re an Inkling youth who was made a member with a little bit of pushing. Venturing out to save the Great Zapfish kidnapped by the Octarians, they fought an extreme battle, triumphing against DJ Octavio, who had brought about this conflict. Having saved Inkopolis from its power outage crisis, they’re a hero who protected the peace. In the middle of a patrol of Octo Valley with Captain Cuttlefish, they encountered Eight. In the thick of the battle, they become separated from Captain Cuttlefish, and their whereabouts became unknown. Rescuing Eight and Captain Cuttlefish, they manage to find them once again, they faint. Their awareness of whatever person they may be stolen, they stood in Eight’s way as a subordinate of the telephone. Agent 3, having lost control of themselves, heartlessly attacked again and again, but Eight, managing to overcome their numerous trials, narrowly won. Agent 3 successfully recovered, Eight opened the door to the promised land, Inkopolis Square.

Other media

Splatoon manga

Both Goggles and Rider act as Agent 3 in the Splatoon manga as Agent 3 and Agent 3.5. They appear in Chapters 8 and 9, which follow the events of Splatoon's Octo Valley. Both are Inkling boys wearing the full Hero Suit with the addition of wearing the gear they are named after, being the Pilot Goggles and Black Inky Rider. They also use the Hero weapons from the same main weapon class as their usual weapons, with Goggles having the Hero Shot and Rider having the Hero Roller. In the Octo Expansion arc in Chapter 25, Rider mirrors the same role as Agent 3 in the game, where he rescues the Blue Team, Agent 8, and Cap'n Cuttlefish from the blender and later becomes mind-controlled. He also has the cape that Agent 3 wears in Octo Expansion but uses his Gold Dynamo Roller instead of a Hero weapon.



  • In Super Smash Bros. Ultimate, one of the customization options for female Inklings is the ability to play as Agent 3, having a light skin tone and blue eyes, but still carrying the regular Splattershot and ink tank from Splatoon.


Splatoon 2

  • Based on Marie's dialogue stating that Agent 4 is "two years older" than Agent 3, one can assume that Agent 4 is at most 18 years old, as Agent 3 was about 14 years old around the events of Splatoon, and would be around 16 years old during the events of Splatoon 2.
  • It's revealed in the Octo Expansion's art book that DJ Sango (Agent 3's rapper name) and Marina were supposed to have an eight hour long rap battle.
  • The reason for why Agent 3 is able to use many special weapons is explained by Marina, saying that Agent 3 had removed their limiter, which implies that they can normally use many specials and have to use something that restricts this ability.

Splatoon 3

  • Cap'n 3 (the original Agent 3) has several scars on his/her hair.
