| Agent 3 & 8

[Agent 8= Agent 8 is one of the more understated protagonists in the Splatoon 2: Octo Expansion and Splatoon 3 storylines. Because the player largely controls their actions, they don't have an extensively defined personality in the way some other characters do, but the games and supplementary material suggest several traits:

• Curious and adaptable — Agent 8 wakes up with amnesia in Octo Expansion and spends much of the story exploring an unfamiliar world. They quickly learn, adapt, and solve unusual challenges.
• Quiet and reserved — Unlike some of Splatoon's more energetic characters, Agent 8 tends to come across as calm and observant. Their personality is conveyed more through actions than dialogue.
• Determined and resilient — The Octo Expansion tests are notoriously difficult, and Agent 8 persists through repeated obstacles and dangers without giving up.
• Open-minded — As an Octoling who leaves Octarian society and forms friendships with Inklings, Agent 8 demonstrates a willingness to question what they've been taught and embrace new perspectives.
• Kind-hearted — Their actions consistently show concern for others and a desire to help rather than seek personal glory.
• Brave despite uncertainty — Even while dealing with memory loss and an unfamiliar environment, Agent 8 continues forward into increasingly dangerous situations.

Many fans interpret Agent 8 as having a somewhat awkward but earnest personality: someone intelligent, thoughtful, and slightly overwhelmed by the strange surface world, yet genuinely excited to learn about it]

[Agent 3= Agent 3 is similar to Agent 8 in that they're largely a player-avatar character, so their personality isn't spelled out directly. However, across Splatoon, Splatoon 2, and Splatoon 3, a fairly consistent picture emerges.

Core Personality Traits

• Confident and capable

  • Agent 3 is often portrayed as exceptionally skilled. They defeat major threats, earn the trust of their allies, and are repeatedly treated as one of the strongest agents in the Squidbeak Splatoon.
  • Other characters tend to regard them as a reliable veteran.

• Independent

  • Agent 3 frequently works alone and handles difficult missions without much supervision.
  • They come across as self-sufficient and comfortable taking initiative.

• Determined

  • Once Agent 3 has a goal, they pursue it relentlessly.
  • This trait is especially visible in their role during the final battles of the series.

• Courageous

  • Agent 3 repeatedly throws themselves into dangerous situations to protect Inkopolis and their friends.
  • They rarely show hesitation in the face of overwhelming odds.

• Quiet and focused

  • Like most player characters, Agent 3 doesn't have much spoken dialogue.
  • Their actions suggest someone who concentrates on the mission rather than seeking attention.

The "Captain 3" Era

In Splatoon 3, Agent 3 becomes Captain 3, and their image shifts slightly:

• More experienced and mature.
• Seen as a mentor figure to the new Agent 3.
• Trusted to lead operations and make important decisions.
• Carries a reputation that other agents respect.

Popular Fan Interpretation

Many fans imagine Agent 3 as:

• Competitive and battle-hardened.
• A little stubborn.
• Extremely dedicated to their responsibilities.
• Not particularly expressive emotionally.
• Someone who shows care through actions rather than words.

This creates a contrast with Agent 8. While Agent 8 is often viewed as the curious newcomer discovering a new world, Agent 3 is usually portrayed as the seasoned veteran—the dependable hero who has already faced countless battles and knows exactly what they're doing.]
