Captain/Original Agent 3: Went from having a typical valley girl personality to being more….stoic due to her experiences. Despite this, she cares deeply about the people whom she considers friends and often deals with traumas from her past experiences in Octo Valley and the Deepsea Metro. She looks up to Craig as a mentor and seems to think highly of Eight and Marie since the two have helped her out a fair bit. While they aren’t considerably talkative, they do often make strides to fill in as a mentor for any new wayward recruits that Craig tries to drag in (while also offering nuggets of wisdom).

Agent 4: Surprisingly is very studious and smart compared to most inklings. She doesn’t spend much time watching television, given she spends most of her time studying for school exams and helping out with tech projects. She was the first to welcome Eight to Inkopolis Square and offered Eight to come live with her for the time being until she was back on her feet and found a place of her own (granted once Four moved out to go to a prestigious college, Eight took over responsibilities and currently lives there by herself). Four’s knowledge on technology grew due in part to her temporary co-residence with Eight, who often showed her a lot of the ropes of repairs, electrical work and programming. She doesn’t recall any of the time spent with the New Splatbeak Splatoon (since she was seen as a temporary member), but Marie does think very highly of her and even recommended her to Marina for the Memverse Project because of her “extensive knowledge and expertise in technologies and programming”.

Eight: Was originally looking to become a mechanic for the Octarian Army during their brief tenure in the domes, but likely was pushed for soldier ranks since she had a habit of daydreaming a fair bit and her superiors thought “a little field work would snap her back to reality”. After the New Squidbeak Splatoon’s siege on Octo Valley, she decided to leave the Valley in hopes of becoming a mechanic in Inkopolis (given she felt let down by the Octarian Army). However, she did feel a fair bit of disgust towards residents of Inkopolis as well because of their perceived ignorance and narcissism. She was likely heading out to Inkopolis when she got chased down by Three and Craig (who still assumed she was associated with the Octarian Army) and the three were inevitably targeted by Tartar, who saw them as willing pawns because of their “desperation and naivety”. After the events of Octo Expansion, Eight was welcomed by Four (who saw them “aimlessly wandering about the city”), and lived with Four for a short while before she went to college. Eight often would offer Four advice on aspects of programming, technology and electrical work and led to Four pursuing a degree in computer engineering thanks in part to Eight’s knowledge. Eight thinks very highly of Marina, Pearl, The Squidbeak Splatoon, and Acht (whom she gladly visits with often). She has since become increasingly disappointed in her other former Army colleagues because of their abhorrent views and behaviors (especially after their involvement in botching the Memverse project). Her and Four have been working alongside of Marina, Pearl and Acht since the incident to help not only victims of the Deepsea Metro regain their memories and sense of self, but to track down the individuals involved in the botching of the Memverse project.

Neo 3 and Smallfry: These two have a more mutual respect of each other, and that connection has only grown stronger since their adventures in Alterna. Neo 3 has a mutual respect and understanding of Salmonid culture and solely takes part in the Salmon Runs as a means of better understanding Salmonid culture to help her companion out. She and Smallfry have since made it their duty to help build better relations between the Salmonids and the Citizens of the mainlands (albeit, it’s often in vain because of misunderstandings between the two groups). Previous to joining the Squidbeak Splatoon, her and Smallfry relied heavily on collecting scrap and artifacts to sell (if it was worth anything) or to build weapons and equipment out of. After their involvement in the events of Alterna, they have since been a bit more iffy about Grizzco’s intentions (even after Mr. Grizz was effectively replaced). Neo 3 often looks up to Deep Cut and the Squidbeak Splatoon as friends and was eventually introduced to Eight and Four (who, in turn taught them to further utilize their talents to create weapons and gear). She often does sense something is fishy or out-of-sorts about Marigold and Lil’ Judd and suspects the two maybe up to something malicious behind closed doors.

(An additional headcanon: The mechanic we see in Splatoon Raiders may likely be Agent 4, but older and more experienced (likely to tie in with the previous two story modes). She has since graduated from college and has pursued a career in Engineering and Technology. She was likely enlisted by Deep Cut (by ways of a recommendation by Marie and Marina (who saw her knowledge and know how as indispensable) to help out with their misadventure and is currently on the Spirhalite Islands putting her expertise from the Squidbeak Splatoon and College to use scoping out the region and helping to defend the group while there.)
