Agent 3 (Splatoon)

Agent 3 is the role the player assumes in Octo Valley, assigned by Cap'n Cuttlefish.

Appearance
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.

History
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.

In Splatoon 2, the role the player takes in single player has been replaced by Agent 4, and Agent 3 was mentioned various times throughout the game, and is on a mission with Cap'n Cuttlefish.

Etymology
The name Agent 3 was given by Cap'n Cuttlefish because Agent 1 and Agent 2 are Callie and Marie, respectively. Agent 3's real name is never revealed.
