I have been living with this headcanon/brainrot about Athena (both from Epic the Musical and pjo) for a long while and a warning for the faint of heart, you know what read it anyway cause it haunts me , so everyone else has to be haunted by it too, cause I am petty like that.
Most people might be aware of the myth that Athena sprung from Zeus's head fully formed and in battle armor, but a few might not know the preceding myth, so here's a quick recap:
Zeus married the titaness Metis, who was the titaness of wise counsel, wisdom, and planning. She was also Athena's mother. Metis was his advisor, both an indispensable aid and threat to him, given her power and cunning. But it's no Greek mythology without a son overthrowing the father archetype haunting the narrative. There was a similar prophecy about Metis's second child being so powerful that he would overthrow Zeus. Mind you Metis was pregnant with Athena when the following events transpire:
Zeus being Zeus, paranoid and power hungry, the King of the Gods and the God of "Justice" manipulates Metis into playing a shape-shifting game and when Metis turned into a fly , he swallowed her whole. [I know Greek patriarchs have a thing for eating their children or spouses pregnant with said children. Runs in the family, apparently]
Mind you in Greek myths, swallowed children, or in this case, swallowed wife pregnant with said child stay alive for a good amount of time even inside someone else's organs. So Metis gives birth to Athena inside Zeus's head and raises her there. She teaches her warfare and strategy until Metis herself eventually dies, i.e., her essence fades. Knowing what she must do to not meet the same fate, Athena hammers on Zeus's skull from the inside to escape. Everyone knows the rest of the myth.
But imagine Athena's first lesson being that the man she calls her father is the one who killed her mother and almost killed Athena herself by swallowing Metis so she must do everything in her power to survive and avoid that fate by staying on his good side. To try and fit in this twisted family of immortals, half of who hate her existence and half who are indifferent to him. So she does exactly that.
Think of Athena asking to be a Virgin Goddess from learning of what comes of marriage with gods.
Now, the continuation of Athena's myth is that she goes to Atlantis to train with the sea nymphs. There she makes her first ever friend and someone she comes to dearly love, Pallas. Greek myths being allergic to happy endings, one day when Pallas and Athena are sparring as they do a bit more seriously this time; Zeus being a nosy bastard decides to spy in just when Pallas is about to land a finishing blow on Athena. Thinking she might kill his daughter, he kills Pallas by blasting her with his lightning. Athena, being heartbroken , Zeus gave her Aegis as an apology. The continuation of this is that Athena adopts the namesake Pallas Athena and even carves a statue in likeness of her friend called Palladium and then more.
But think of Athena heartbroken and bitter as the Goddess of Wisdom learns her second lesson, then she must abandon all personal relations and sentiment before her father ends it for her in one way or another. For Pallas was the first true relation in her life after her mother.
Keep in mind that Pallas is Poseidon's granddaughter through his firstborn son and heir Triton. This is the point that sparks eternal enmity between Athena and Poseidon, and all those who come after will suffer in the wake of this tragedy.
So Athena chooses to remain alone and without a friend to avoid such a situation. Imagine Athena being hurt, especially brutally, when Odysseus says: "Since you claim you are so much wiser, why's your life spent all alone? You're alone!"
Because that's exactly it. Athena is wise. She knows the consequence of endearing herself to someone again so she stays alone to avoid such a thing and yet coming from someone who is so close to being her first friend in a long time, hurt and enraged she leaves.
Now, when finally Athena comes to terms with her friendship with Odysseus she finds yet again that her father Zeus struck him and his crew in a similar fashion to Pallas , yet again ripping her only friend away from her .
He is not dead yet, and Athena isn't about to let that happen. This time, she fights against Zeus, risks her life and position of being the favorite, and her survival method all because she can't bear to see Odysseus die.
Think of the agonizing fate of Athena, repeatedly being traumatized by her father yet having to do his bidding and stay on his good side to survive and live not for herself for she lives in misery but for the people who suffered for died for their association with her. In her eyes, she must suffer tenfold for letting this happen thrice, for all eternity under the man who so wretchedly ruined her life.
Y’know I like how some people headcanon Poseidon makes angry fish noises while Athena makes angry owl noises. This is absolutely canon and nobody can convince me otherwise
