Well, perhaps Percy has the same stormy - blue eyes as Poseidon, which are like the sea in a tempest. And his hair might be unruly and dark like Poseidon's, as if it were waves whipped up by the wind.
In some fanfictions, Percy might have an aura about him that is similar to Poseidon's. His movements could be fluid, like the ebb and flow of the ocean, which is a very Poseidon - like trait. Also, there could be little details like Percy having a certain pattern of freckles or moles on his face or body that mirror Poseidon in some symbolic way. His expressions might even have a hint of the ancient and powerful look that Poseidon is often depicted with, a sort of calm yet imposing presence.
One possible plot point could be that Percy's resemblance to Poseidon causes confusion among the other characters. They might mistake him for Poseidon at first glance, leading to some comical or tense situations.
Well, in the Percy Jackson universe, there's no official indication that Poseidon would be into watching Percy fanfiction. He's a god with his own set of concerns like ruling the seas and dealing with other gods. Fanfiction is more of a mortal concept, and it's hard to imagine him sitting around reading or watching it.
In fanfictions, Poseidon often interacts with baby Percy in a very gentle and protective way. He might use his powers to create a safe environment for Percy, like a special underwater grotto where Percy can be hidden from danger. Sometimes, he sends sea creatures to watch over Percy, like dolphins or friendly sea nymphs.
In certain fanfictions, Poseidon might hurt Percy's reputation. He could do something that makes the other demigods look at Percy in a different, negative light. This could be by making decisions that seem to favor Percy too much, causing jealousy among others, or by getting Percy involved in some political mess within the godly realm that Percy has no control over. This can lead to Percy being ostracized or having to deal with a lot of unnecessary drama and pain.
In some fanfictions, Harry might be described as having his mother's bright green eyes, which were said to be very expressive. Also, he could have her delicate facial features, like a small nose and a soft jawline. Maybe his hair has the same texture as his mother's, which could be a bit wavy.
Often, Poseidon is depicted as heartbroken. He may withdraw from his normal duties and just sit in his underwater palace, watching over Percy's lifeless body or the place where he died. He could also be shown as being very quiet and solemn, his usual boisterous nature gone, replaced by a deep sense of loss.
Poseidon might be extremely angry. He could immediately seek revenge on the abuser. After all, Percy is his son and he has the power to protect him.
This concept shows Poseidon as a god who adheres to certain values. He believes in teaching Percy right from wrong, which reflects his own sense of morality. It also portrays him as a bit traditional. In the world of the gods, where power can be used in many ways, he chooses this rather old - fashioned way of discipline, which might suggest that he has some conservative views on parenting.
The relationship could be shown as a curious one. Since Percy is a baby, he might not fully understand who Poseidon is, but there could be an instinctual bond. Poseidon, on the other hand, could be filled with a sense of wonder at this small version of his son, seeing all the potential in him. He might try to communicate with Percy in gentle, non - verbal ways, like sending small ripples of water to make Percy laugh.
It can also make Percy more empathetic. Since he has such a powerful and protective father, he realizes the importance of protecting others too. He may be more likely to step in and help those in need, just as Poseidon does for him. This protection also gives Percy a sense of security that allows him to explore his own identity and powers more freely. He doesn't have to constantly worry about being alone or unprotected, so he can focus on growing as a hero and as a person.
