Saros: he's a bit prideful and argumentative, a little bit too stubborn to realize his way of things is not always the right way (mostly a negative trait from myself cause Saros is just a self-insert at the end of the day)

Sun: he gets waaaaaay too emotionally invested, even if it doesn't make sense to. arguments with him usually end up leaving him frustrated and in tears, no matter what the nature of the argument was or whether or not it ended in his favor.

Sourire: he never gets loud or snap but boy does he become stern and broody for a little while during and after the ordeal. that being said, he's much more of a defuser than any of my other OCs because he focuses on finding common ground rather than defending his point or proving the other person wrong.

Aberration: this MFer will start swearing and shouting like he's Sol Badguy from Guilty Gear, he does not know the meaning of "back down" long until after the argument ends and he has a chance to think things over with a clearer head. he does eventually apologize once things have settled down, at the very least

Saros - https://www.youtube.com/watch?v=LIlZCmETvsY
more of a meme than anything but i can see him doing the choreographed dance + dragging a few other doctors / colleagues into it with him

Sun - https://youtu.be/4XcTZNafjcQ
the melancholy but high tempo vibes, the romantic but self-downplaying lyrics, it's all there for him

Sourire - https://www.youtube.com/watch?v=U7L-3VXAkSA
this MV is both where i partly got his visual design reference from + his backstory of him being a wandering Infected until he finds Rhodes Island

Aberration: https://youtu.be/9Y0_CVX1hok
whoops another eve song! like sourire, the MV inspired both his visual motifs and his struggle with having seaborn blood coursing through his veins, transforming him into something he considers ugly and warped

Sun: this dude's the type of guy to always offer some of his homemade cooking, whether it's for celebration of an accomplishment you achieved or it's to help lift your spirts in time of duress. his office and his home is almost always open to others, his free time often set aside to bond and connect with his fellow colleagues and or patients.

Sourire: don't ever let Sourire know what's troubling you because 99% he will then immediately set out to find the problem and resolve it for you, even if you didn't ask for his help. if the lightbulb in your room exploded, he'll install a new one for you when you're not even looking. having problems talking to your crush? Sourire will bluntly walk over to said crush and subtly suggest that you've been feeling lonely and need someone to spend time with. his loved one's problems are his problems and he won't stop until he either fixes them or finds someone else who can do so for them.

Aberration: Abby's tough-guy persona honestly makes it easy to tell how much he cares tbh; he can be rude and off-putting in one breath but in the next he'll offer someone who's standing out in the rain his jacket because it pisses him off that they wouldn't take their own health more seriously. while he complains quite often about the circumstances he often gets himself into, he is a steadfast friend and will never turn his back on you

they’d all be relatively small and intimate! sun doesn’t want to make a big public deal out of the romantic bond that he shares with whoever his partner will be and for the most part each timeline has his significant other agreeing.

there is a very quiet ceremony for each timeline that goes a little something like

HoshiSun: they wed in Lungmen, their closest friends and compatriots invited out to a seaside wedding (think Shek O beach near Hong Kong)

ReedSun: while they first get wedded aboard Rhodes Island’s flight deck (with friends and family present) in the interest of Reed’s safety at first, on their first anniversary Sun takes her to Victoria to have a private renewal of their vows in a quiet, heavenly chapel

KalSun: Kal’tsit doesn’t really want to deal with the theatrics of a wedding ceremony, opting instead to say her vows and have Sun say his as soon as they get engaged. this is both because she doesn’t want to deal with her personal life becoming public in any sense AND some part of her is still worried that Sun might one day disappear, despite his reassurances and his pledge to be by her side for however long of his life remains. so she wants everything said and bound now, before it’s too late, and everything else doesn’t matter.

Saros: literally whatever music i like since saros is just me but a kangaroo rofl

Sun - big on electronica, lo-fi and shoegaze music. he's kind of a big music head even if he doesn't play any instruments and can only sing decently enough. naturally this mean's he's a big fan of D.D.D

Sourire: he's a bit of a quiet country boy who likes intimate acoustic guitar performances and little else at first but after coming aboard Rhodes Island he's learned to develop an affinity for jazz, thanks to Ellipses and her penchant for the saxophone! another genre he'd be into before hand is some good old pop-punk ala Yellowcard or Blink-182's self titled album.

Aberration: this man is all about the rock music whether it's metal, post-hardcore, grunge, screamo, you name it, abby's prolly already listened to it before the band got big. despite this proclivity he's got nothing against "quieter" music and can honestly enjoy most things. except for country.

Sunless: Justino's name means "just", which is a pretty good descriptor for his moral compass. He took his codename during the Kazdel Civil War, when he was mired in tragedy and death which eventually compelled him to enlist as part of the front line forces despite never having been trained in combat until then. Justino had meant for it to be an affirmation that he would be by his fellow soldiers' sides, even if the sun were to disappear, yet in the end it amounted to a reflection of how dark his heart had become with guilt and despair. And on that note...

Sunrise: After certain events, he swore that he would never take his life for granted ever again after everyone had fought so hard to protect it despite the worst of his self-destructive tendencies flying right in the face of their efforts. The change to his old alias signifies the beginning of a long healing process.

Sourire: His real name is Oliver but is more commonly referred to as "Oli." I picked this as his name because I'm cringe and wanted to make a very light reference to a band I listen to by the name of Bring Me The Horizon (the lead singer of the band being Oliver Sykes). His codename means "to smile", which is both a sort of jab at himself and a reminder of what he should continue to bring to others. Even if his life has ultimately changed directories thanks to the horrible Oripathy infection forcibly inflicted upon him, all he wants is to help make a better world with the time he still has.

Aberration: His real name is Nox, a gender-neutral name for "night". As for his codename, he first took this mantle up because he felt like the odd one out at Rhodes Island but eventually his view on the codename began to change. It soon became an expression of his own individuality, something that the sea and its myriad monsters could never take away from him.

Cían (ReedSun timeline): he struggles for quite some time with internalized self-flagellation, blaming himself for so much of the tragedy that is completely out of his hands. it takes a lot of time for him to move on past this, especially when he has a particularly bad setback involving the death of one of his friends.

Musician (HoshiSun timeline): he has a bit of an issue feeling like he'll never amount to the example set by his prestigious and outstanding parents, though he chooses to work through this by focusing on furthering his career in music + training hard every day to be an exemplary Defender Operator at Rhodes Island. (fun fact: Musician Isa starts his music career far earlier than any of his other timelines)

Composer (KalSun timeline): much like dear old mom and his dad's old bad habits, he has a problem of letting his work and responsibilities take complete control of him. ultimately it takes his friends and family to get him to properly balance his work and his personal time and while he may not show it so easily in this timeline, he still cherishes and appreciates the efforts of his loved ones despite his insistence on burying himself in work out of self-assigned "duty".

Saros - siesta bc he wants to make fun of the fuckboys there while catching some concerts

Sun - he'd want to take a trip to yen, being very interested in its culture, although he'd explicitly avoid the obvious "tourist visits" and guides, instead opting to drive around the more hidden and local spots so he can make the trip a memorable experience that doesn't belong to anyone else besides himself.

Sourire - he'd like to go back to Victoria, to his hometown of Greystone. unfortunately, he knows it's impossible since anyone who's contracted Oripathy are exiled for the safety of the hamlet's already small population. all the same, whenever he's in Victoria, he tries to find café shops with items and brews that make him feel just a little less homesick.

Aberration - abby doesn't really make vacation plans, which means he finds himself being dragged on other people's vacations. it doesn't really bother him much but admittedly it does leave him feeling out of depth at times, although he always ends up having a fun time whether it's just getting some downtime with his companions or finding something that piques his interest. (there's a very small lockbox hidden underneath his bed for very important possessions of his and that's where those vacation souvenirs get stashed to)

swapping OC gears for a bit here

Sourire met Ellipses during the start of the Lungmen-Chernobog crisis, which definitely doesn't make for an ideal romantic setting. It was during the fight with Skullshatterer and Ellipses was struggling to give orders to her team thanks to her frail constitution at the time. In the nick of time, Sourire swooped into the situation and fought off Skullshatterer who was going in for the kill on a distracted Amiya, providing assistance to Ellipses' team for the remainder of the battle.

Despite being "a civilian", he chose to stay by Rhodes Island's side and continued to fight against the Reunion forces invading Lungmen. For this, once all was said and done, Ellipses personally vouched for Sourire to be admitted to Rhodes Island; both for his Oripathy infection and to vouch for him as an potential Operator.

Over time after joining Rhodes Island, Sourire never really parted from Ellipses or her team, instead only getting closer to them as he slowly adjusted to his new family and friends. Bonding over their love of music and playing instruments (Sourire the guitar and Ellipses the saxophone respectively), showing and teaching her skills belonging to both a bartender and a barista and just being able to confide in one another about the horrible traumas they've had to live through eventually culminated with them becoming inseparable.

Hoshiguma: staring over the downtown lungmen skyline together, the glow of the city below as Hoshi and Sun sit on the edge of an abandoned high-rise they scaled together with the neon glow making her so heavenly, despite the somber look on her face as she looked at a place steeped in bloody history that she personally experienced.

Reed: the moment that Reed trusted Sun enough to fall asleep close by, since she's so guarded despite her selflessness. when Reed awoke, she found Sun fast asleep at his desk and a blanket she hadn't had before covering her snugly while she had been resting on the couch in his office.

Kal'tsit: it was a moment that caught him completely off guard but it was what eventually allowed the both of them to reconnect properly. going to her office he happened upon her reflecting upon a old photo from the old Babel days, a group selfie with Sun and Kal'tsit front and center. they had forgotten whatever business they needed to attend to and began talking for hours on end, about the past and its mistakes, then the future and healing.

they're not one whole ship! it's three different timelines because both sun and i like Strong Women Who Can Kick Our Ass

otherwise, i suppose a main central theme with all these ships is emotional reconciliation. sun has his fair share of traumas that he has to unlearn and whichever timeline he's in, his partner helps in their own way both because of the bonds they share and the kindness they have.

and it goes both ways of/c bc sun's a giver and wants his beloved to be happy and recover past whatever baggage they may carry, whether it's the emotional hurt ch'en inflicted on hoshiguma by leaving the way she did in Ch 7-8 on top of the sole survivor guilt she has, reed's refusal to accept herself as anything more than just a traitorous shadow of a cruel king, or kal'tsit's inability to let her guard down and keep people at a distance

if we're talking just arknights, then...

Dr. Saros of Rim Billition, ex-Laterano Spec Ops and Babel / Rhodes Island's tactical advisor, is a kangaroo man

Dr. Sunless / Sunrise, runaway Perro therapist from Bolívar, is the Doctor OC of mine who did get amnesia / goes through most of AK's main story, has so much depression

Sourire, Sarkaz Operator who grew up in a humble hamlet in Victoria until he contracted Oripathy, wandered the world helping people however he could as a wandering swordsman before joining up with Rhodes Island during the Lungmen-Chernobog crisis.

Aberration, an Operator from Aegir who's home and nearly his entire family was lost to the Seaborn, is a bit of a hardass but is one of the most compassionate and caring people aboard Rhodes Island who had been caring for him since he was young and frail

i have a few more but these are my main arknights OCs! (don't get me started on the rest of them outside of arknights or we'll be here forever)
