While he stayed out of the first titan war for the most part, his daughters Metis & Styx were definitely Olympian loyalists, with Metis even being the one who made the potion Zeus served to Kronos (making him throw up his kids) but his daughter Clymene's sons with Iapetus were divided.

After the Titanomachy, he & Tethys raised Hera, who loves them dearly.

His daughter Metis is married to the new king Zeus, so everything should be going great for their family right? Except no, his son in law does the same thing to his pregnant daughter that his cannibal brother did to Zeus's siblings, and unlike the children of Kronos, his daughter wasn't lucky enough to escape her cannibalizer.

His granddaughter is born eventually, but she sticks by Zeus. She's even his favorite with Zeus getting credit for creating her alone. She never mentions her mother, Oceanus's daughter, it doesn't seem like she even cares.

And Hera is now married to Zeus, she loves him, so he tries to support her, only to see her heart get broken over and over again. Hera loses her patience when it comes to Leto, every god including her own mother betrays her, but Oceanus & Tethys still stick by her.

Maybe Oceanus is grateful when Hera spares his granddaughter Maia from her wrath, despite Maia being just as guilty of having an affair as Leto? But when it comes to another one of his granddaughters, Io, she's not so gracious, and unlike Leto & Maia, Io never even accepted Zeus's advances. She was assaulted, by the same cannibal who ate his daughter. Fortunately Io survives, but Hera made it clear she's not making exceptions for his family anymore.

Yet Oceanus still loves her. She's just as much a daughter to him as the others, and she loves him & Tethys, she comes to them with tears in her eyes constantly. Zeus's actions sucking out her joy and warmth more and more each time they see her. Hera has abandoned her kindness, only hurt is left in his once affectionate foster daughter.

She makes him & Tethys swear to not help Callisto, he loathes doing it, but if he betrays Hera the same way Rhea did, it would destroy her, she would never trust him again. Everyone else has always chosen Zeus over her, even though it was him who was the source of Hera's misery, and as he only ever admitted to himself, the source of his own misery as well.

Kronos comes back, & the rest of his brothers.

Hecate, once an ally of Zeus, joins the Titans. While beloved by Demeter, Hecate is just as loving of a mother as the goddess she served, and there is no place for her children. She brings with her some allies from the Underworld in Nemesis, Morpheus, & Melinoe.

His grandson & nephew Prometheus expects loathing from his father as he sided with the Olympians, but Iapetus only embraces him upon reunion. Oceanus sees his brother's eyes burn with rage once he learns Zeus's brutal punishment & torture of his son.

The desire for revenge by those locked in Tartarus are clear, but Zeus has hurt them in more ways than one. Hyperion has lost Helios & Selene and Koios has lost Asteria just as permanently as Oceanus has lost Metis, he grieves with them. Their children fought for Zeus and the Olympians over their own kind, the Titans, just to be brutalized, abandoned, & tortured when they were no longer wanted.

People sing praises to the Olympians, but all Oceanus can see is the pain they caused his family, and all this time, he did nothing.

He didn't help dispose of his abusive father, he didn't stop Kronos from eating children, he stood by as his own children & grandchildren fought each other in the first Titan war, he didn't retaliate for the murder of Metis, nor for the injustice faced by Prometheus, not even when his own daughters & granddaughters were getting assaulted by Zeus, Poseidon, & their spawn, and he's tired of doing nothing, so he joins.

All he makes Kronos promise him in turn is that Hera will remain unharmed under Kronos's new reign.

Sigh. This is my punishment. /j

For reference, this is the post they’re referring to from the lovely @percabeth4life where she examines the relationship dynamics of Percy/all the male Titans. TLDR, a very unhealthy relationship in general, though I think anyone writing it would be well aware of that.

Nevertheless, I’ll give some headcanons because I really do think it would be interesting. Note that this is assuming Percy with the male Titans, since that’s what Life’s was. Also, while there will be similarities in our interpretations, there are also differences.

Their wives are all well aware of this relationship and are generally the kindest ones to Percy. They’re the ones who will steal him away under the guise of fashion or the like in order to give him a moment of rest and the ability to let his guard down for a moment. Thetys is the most helpful in this regard, she’ll take him to areas of freshwater where her husband has little control and allow him to soak. It isn’t as good as saltwater, but it still helps.

They would all be incredibly controlling and demanding for Percy’s time. Kronos would get the most, seeing as he’s the king of the Titans, however that also means he’s busy and during those times Percy is taken by one of the other siblings.

Speaking of Kronos, with him Percy takes the role of some form of servant, most likely a cupbearer (a la Ganymede) so that Kronos can have him around as often as possible.

Kronos can be kind to him at times. If Percy obeys, Kronos is the type to have him sit on his lap and feed him or otherwise spoil him. However, Percy does not really have a choice in any of it.

This applies for all of the Titans. Everything is dubious consent at most. I cannot think of a way that Percy would have any sort of power in this relationship, much less be able to fully consent. However, that is the most I will say on that.

After Kronos, Okeanus/Oceanus would probably get the most time with Percy. This is because he is the King of the Seas and Percy is of the sea by nature of being a son of Poseidon. He would be far kinder than Kronos. Kronos would likely force Percy to sleep in the same room as him, however Okeanus would likely permit him his own (albeit heavily monitored) room. 

As previously mentioned, Thetys steals Percy away frequently. She teaches him more about the culture of the ocean that Poseidon clearly forgot to teach him. Its his main respite and he becomes dedicated in learning the history. Ocean magic is also the only thing even slightly similar to combat he is allowed.

Despite being the nicest of the Titans to Percy, Okeanus still had a tendency of disrespecting his wishes when it comes to physical affection. He had bouts where he will just grab Percy and kiss all over his face, even when he doesn’t want it.

Of the siblings, the Titans of the four cardinal directions are best at sharing among each other, although they still don’t like sharing with Kronos, Okeanus, and Atlas. Since they get the least amount of time with Percy, they tend to spend it sharing him among each other.

Hyperion was actually the meanest to Percy at first, locking him into small spaces as revenge for being encased in a tree. However, he also softened to him the quickest and tends to spoil him with jewelry just as he would Theia, who finds it amusing.

Of course, he tends to expect Percy to wear nothing but that jewelry when with him.

Iapetus likes to watch Percy interact with his siblings and will rarely pull him away. However, when he does he demands to be the only person to have his attention for the hours he has him.

He finds amusement in making Percy do things for him, such as fetching anything he wants, but also dancing and singing.

He’s also the quickest to hurt him for doing anything wrong. Percy learns that if he is to have any disobedience, it shouldn’t be with Iapetus. He has an extremely short fuse and often Percy has at least a few bruises when he is passed to the next sibling.

Koios and Krios are fond of having Percy together. The cardinals are best at sharing, however within them these two will always have Percy together. They’re also the easiest for Percy to persuade to have a moment alone, though that moment is always just a moment.

Atlas actually knows Percy the best of all the Titans with the exception of Kronos.

While he’s an asshole, all of them are, he would also be the most likely of the male Titans to take Percy’s side in any way.

They also spend the least amount of time together doing physical acts. Instead, they often talk, although Percy still isn’t allowed to argue against him.

Instead, especially in the beginning, Atlas is particularly keen on learning about Percy’s interactions with Zoe and Calypso. He also admires Percy’s loyalty to his family and, if Sally is still alive, would actually argue with his siblings to get Percy the chance to see her again.

Despite Okeanus giving him the most freedom and him getting to be in the sea, Atlas contends with Okeanus for the spot of Percy’s (relative) favourite male Titan.

If Percy were to manage to escape, Atlas is the only one who would turn a blind eye and you can quote me on that... in this AU that is entirely in my head.

Oceanus - Hera looked at Zeus with her big doe eyes and asked him to spare the only father figure she ever had while shedding tears.

Hekate - Asteria reminded her niece and nephew and that they owe it to her to save her daughter because Delos was the only land they were allowed to be born on. (Apollo and Artemis obliged and requested Zeus to spare her.)

Nemesis - She's Nyx's daughter and Zeus doesn't mess with Nyx who doesn't play about her kids.
