A unique way to portray their relationship in the Percy Mortal AU could be through dreams. Maybe Annabeth keeps having dreams about Luke before she even really meets him in the mortal world. When they do meet, she feels a strange sense of familiarity. Another way is to have their relationship be centered around a sport that's not typical in the Percy Jackson universe, like skateboarding. Luke is a skateboarder and Annabeth is intrigued by his fearless attitude on the skateboard. She starts to hang out at the skate park to watch him and eventually falls in love. Additionally, the relationship could be shown as a rediscovery. For example, they knew each other as kids in the mortal world but lost touch, and when they meet again as teenagers, Annabeth's old feelings for Luke come rushing back in a new and unexpected way.
One way to portray it uniquely is by having Annabeth's love for Luke be based on a shared interest in art in the mortal AU. Maybe Luke is an aspiring painter and Annabeth is drawn to his creativity. Another unique portrayal could be that Luke has a secret musical talent and Annabeth falls for him when she discovers it during a local talent show. Or, in this AU, they could be partners in a community service project and through helping others, Annabeth realizes her love for Luke.
One good example could be a story where Annabeth's love for Luke is a slow - burn. It might start with her admiring his confidence and leadership skills in a mortal high school setting. Maybe he's captain of a sports team and she's drawn to his determination. Another example could be a fanfic that delves into the internal conflict Annabeth has because she also has a friendship with Percy in this AU, but her heart pulls her towards Luke. A third type could be a story where Luke is in some kind of trouble and Annabeth's love for him drives her to go to great lengths to save him, even sacrificing her own relationships with others in the process.
Their relationship could be shown as a sort of mentorship. Poseidon, as the all - powerful god of the sea, could be teaching Percy the more subtle and complex aspects of his powers. For example, how to control the tides in a way that is not just about brute force but also about finesse. This would make their relationship more than just a father - son bond but also one of teacher and student.
Their relationship could be shown as a partnership in training. Chichi, who has her own martial arts skills, could train with Gohan in a new style that combines Earth - based and Saiyan techniques. This would not only show their mutual respect for each other's abilities but also their shared love for martial arts.
A very different way to show their relationship is if they are both trapped in a magical realm together. In this realm, they have to rely on each other to survive. Hermione uses her intelligence to solve the puzzles of the realm, and Greyback uses his werewolf instincts. As they work together, they start to respect each other. Greyback realizes that Hermione is not just a weak Muggle - born, but a powerful witch, and Hermione sees that Greyback has a side to him that is more than just a blood - thirsty beast. This shared experience could create a bond between them that is both unexpected and complex.
Often, their relationship is shown as deeper and more unbreakable. They've been through Tartarus together, which is like the ultimate test. So in fanfiction, they trust each other completely and are always there for one another.
Nemesis can be shown as having a sense of humor in a twisted way. For instance, when she sets up a trap for Percy, she could leave little hints that are actually funny riddles. This would make her seem less like a one - dimensional villain. Another way is to show her having a soft spot for certain things, like she might love a particular type of flower that only grows in the Underworld.
Their relationship could be portrayed uniquely by setting it in a post - apocalyptic world. Ash could be on a mission to find a way to restore the world and Mew could be the key. Their bond would then be based on survival and hope for the future.
Portray their relationship as a partnership for a greater good. In the fanfiction, the gods are facing a new threat, perhaps a powerful and dark force. Aphrodite and Hephaestus, who are usually at odds in matters of love, come together. Aphrodite uses her beauty and charm to gather information, while Hephaestus builds weapons and defenses. Through this shared mission, they rediscover their love for each other in a way that is both unexpected and unique.
One unique way is to give them a shared hobby. Let's say they both love to paint. Hades paints the dark and gloomy landscapes of the Underworld, and Persephone paints the vibrant and colorful scenes of the mortal world. Through their art, they understand each other better. Also, you could show their relationship as a bit of a role - reversal. Maybe Persephone is the more assertive one in the relationship, and Hades is the one who is a bit shy and reserved. And for a more complex portrayal, you could make their relationship a bit of a mystery to each other. They keep secrets from each other, not out of malice, but because they are afraid of how the other will react, and as they gradually uncover these secrets, their relationship deepens.
You could portray their relationship as a partnership where they cover each other's weaknesses. Thor protects Loki from physical threats while Loki uses his intelligence to get Thor out of tricky situations. For instance, when Thor gets into a fight with some Asgardian bullies, Loki uses his magic to create an illusion that scares them away. And in return, when Loki is in danger of being punished for using magic inappropriately, Thor takes the blame. This would show a deep - seated bond between them.
