Male Agent 8

They have Inkling-like pupils in their eyes, as as opposed to Marina's and the enemy Octolings' colored-in pupil, with an "8" burned into the retina. Their ears are also notably much larger than that of enemy octolings', which are flat. Their left ear is flat, and their right ear has a ridge. he has the mohawk style, presented in the Octo Expansion. he wears a black leather top with a silver zip, leather shorts and black bolts. the top only has the left arm's sleeve, which is tight, and the other arm isn't covered. they have a somewhat mixed skin.

Agent 8 shows aspects of their personality through subtle means. Agent 8 has a fondness for poetry and writes one for every mem cake collected. Agent 8 demonstrates a yearning for life on the surface, participating in Turf Wars, finding a part-time job, and dressing up in fresh clothes. This resolve is shown most strongly in the final area of the Octo Expansion, showing Agent 8 with glowing eyes as they charge through the stage with the Calamari Inkantation motivating them. he is completely stubborn. once his mind is set on something, he just won't stop. even if it hurts him in the process. he's rash and bashful at the same time. he's... somehow zesty.

Agent 8 is the main protagonist of the Splatoon 2 DLC pack, Octo Expansion and the Splatoon 3 DLC Pack Side Order. They are an Octoling who rebelled against the Octarian society after the events of the first Splatoon, during which they heard the Calamari Inkantation sung by the Squid Sisters.Agent 8 was an Octoling soldier for the Octarian army and had a change of heart when the Calamari Inkantation was etched onto their soul. In Octo Valley, Agent 8 encountered Cap'n Cuttlefish and Agent 3, where Cuttlefish had them 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.

As stated by Marina, Octoling minds are altered once they have listened to Calamari Inkantation and after waking up, Agent 8 wanted to get out of the Deepsea Metro and live their life in Inkopolis, rather than return to DJ Octavio's forces. They are called Agent 8 by Cap'n Cuttlefish due to them being identified as subject number 10,008 in the testing facility since Agent 8 forgot their real name after losing their memory.As a result of listening to the Calamari Inkantation, Agent 8 is a big fan of the Squid Sisters, anxiously planning their greeting to the pair upon reaching the surface every night. As stated by DJ Octavio’s Mem Cake, Agent 8 wishes to apologize to DJ Octavio for unceremoniously deserting the army in pursuit of Inkopolis, as well as recollecting their old Octarian friends, specifically an Octoling whom Agent 8 fondly remembers, and hoping that they do not think badly of their decision. Agent 8 comes to greatly admire Marina, to the point of expressing the notion of wanting to be just like her.
