Agent 8

Agent 8, also referred to as Number 10,008, is a playable Octoling and is the protagonist of the Octo Expansion, and an NPC in Splatoon 3: Cuttlefish Expansion

Appearance
Agent 8 can have a variety of appearances, depending on the player's choice of gender, skin color, eye color, and hairstyle, as well as their current ink color.

Their outfit consists of a black leather crop top for females or a slightly longer shirt for males with one long sleeve, a leather skirt for females or pants for males, boots, and a purple sleeveless jacket.

History
Agent 8 was an Octoling soldier for the Octarian army and had a change of heart when they heard the Calamari Inkantation during the final battle of Splatoon, etching it onto their soul. According to Marina, Octolings that hear the song become discontent with Octarian society and choose to strike out on their own. In Octo Valley, Agent 8 encountered Cap'n Cuttlefish and Agent 3, where Cuttlefish had Agent 3 attack Agent 8. The two battled until all three of them were attacked by someone and were knocked into the Deepsea Metro. Agent 8 lost their memories from injuries suffered during the fall through the ceiling and became a test subject of the metro.

They are called Agent 8 by Cap'n Cuttlefish as a shortened form of the name the Telephone gave them, subject number 10,008, since Agent 8 forgot their real name after losing their memory.

Role
They are called into action from Deepsea Drop, because Agent 8 already knows their way around a Kamabo Co site. Agent 8 gets yanked into the shadows, and the second to last boss was Sanitized Agent 8, before being cured by Agent X's Low-Tide ink.
