One plot idea could be that in the midst of chaos, Percy and his partner find a moment of peace and connection during the make - out session. Maybe they're in a dangerous situation, like in the middle of a monster attack, and their closeness gives them strength. Another could be that it's a dream - like sequence where the chaos around them is a manifestation of their inner turmoil, and the make - out is a way to ground each other.
Well, perhaps there's some sort of magical interference causing the chaos. Percy and his love interest start their make - out session, but it gets interrupted by a spell gone wrong. This leads to them having to work together to fix the chaos while still dealing with their new - found feelings. It could also be that the chaos is part of a larger prophecy, and their make - out session is a sign that they are the ones to bring order, in an unexpected way.
A plot idea might be that the make - out session occurs during a time when the barriers between different mythological realms are breaking down (the chaos). Percy and his significant other are from different realms and their relationship is seen as a way to either save or doom the combined worlds. Their make - out session is a moment of unity in the face of all the disorder and confusion, and they have to decide how far they're willing to go to keep their relationship and the worlds intact.
Obviously Percy Jackson himself could be one of the characters. Annabeth Chase would be a likely partner as they have a long - standing relationship in the Percy Jackson series. Another possibility could be Nico di Angelo. He has a complex character arc and could be involved in a make - out session in a story that explores his relationships in a more romantic context during a chaotic situation.
One idea could be Percy being chosen as the Chaos Champion and having to face off against an ancient, long - forgotten evil that is emerging from the darkest corners of the Underworld. He'd have to use his new - found powers granted by Chaos in unique ways, like controlling the very essence of water in ways he never thought possible, such as turning it into solid light constructs for defense.
One idea could be Percy having to face a new type of chaos monster that is immune to his usual powers. He would have to find a way to adapt and use his wits more than his strength. Maybe he teams up with an unexpected ally from the realm of chaos.
One idea could be Percy using his skills in a chaotic new world filled with strange mythical creatures that no one has ever seen before. He has to navigate through this chaos and find a way to bring order to this new part of the mythical realm.
One idea could be that Percy discovers a hidden connection to Chaos while on a quest. Maybe he stumbles upon an ancient artifact that has the power of Chaos within it, and it starts to change him in unexpected ways. For example, he might gain new powers that are related to the primordial chaos, like the ability to manipulate energy in a more chaotic and unpredictable form.
One idea could be Percy discovers new powers as the Host of Chaos and has to learn to control them while facing an ancient enemy that was sealed away long ago. He could struggle with the chaotic nature of his new abilities and how they affect his relationships with his friends at Camp Half - Blood.
One idea could be Percy facing a new type of monster that is immune to water. This would really challenge his typical combat style. Another could be Percy having to team up with an old enemy to defeat a greater threat that endangers both the mortal and demigod worlds. Maybe he has to journey to a completely unknown realm within the Chaos to retrieve a powerful artifact that is the key to saving his friends.
One idea could be Percy discovering his new role as the Father of Chaos gradually. Maybe he starts having strange dreams or powers that he can't explain at first. For example, he might accidentally create small chaos portals without realizing it. Another plot could involve Percy having to deal with the other gods' reactions. Some would be fearful, while others might see it as an opportunity to gain power through him.
One idea could be Percy losing the Blades of Chaos and having to go on a quest to retrieve them from a powerful new enemy. Maybe a dark sorcerer has stolen them to use in a ritual that would bring chaos to the mortal and demigod worlds.
One idea could be that Percy has to team up with Lady Chaos to stop a new threat that is emerging from the Underworld. This new threat is causing chaos (ironically) among the gods and demigods alike. They have to journey through different realms, facing various monsters and challenges along the way.
