Mermaids in the Percy Jackson mythology can be a source of knowledge. They've been in the ocean for a long time and might know secrets about ancient artifacts or prophecies. They could also be a form of protection. Since they are part of the ocean ecosystem, they could protect certain areas or creatures. Their physical characteristics, like their fish tails and ability to breathe underwater, set them apart from other beings in the Percy Jackson world and give them a unique role to play.
Mermaids can fit in as another species in the Percy Jackson mythology. They are part of the rich tapestry of sea - related creatures. They might have their own relationships with the sea gods. For example, they could be servants or allies of Poseidon. Their existence adds more depth to the underwater world that Percy often has to deal with.
Well, take the 'Quest Log' ability. In Percy Jackson, quests are a huge part of the story. An OC with a 'Quest Log' ability can have a mental or physical log that details the steps and requirements of a quest, just like in a game. It can show them the main objective, side quests, and even give hints on how to complete them. This fits into the mythology as quests are often complex and having such an ability would make the OC more efficient in fulfilling their tasks.
Well, it could be a really interesting and terrifying addition. Maybe it could be some kind of ancient monster that was locked away long ago in the world of Percy Jackson. It could be released by some dark magic or an evil demigod. The xenomorph's ability to adapt and its deadly nature would make it a formidable foe for Percy and his friends.
Percy's water - controlling abilities would be unique in Asgard. He could use it for defense and offense. For example, he could create water shields or water whips to fight against enemies. His ability to breathe underwater might not be as useful in Asgard directly, but it could come in handy if there are any underwater areas or if he has to deal with water - based magic there.
Percy could fit in as a strategist. His experience in dealing with various gods and monsters gives him a unique perspective on handling threats. He might suggest different approaches that the Avengers haven't thought of before, like using the environment in a more creative way, similar to how he uses water in his battles as a demigod.
The author can keep the core elements of the Percy Jackson mythology intact. For instance, the existence of the gods, the demigod powers, and the various monsters. But they can add a new layer to it by exploring how female Percy Jackson's sexual orientation affects her relationship with the divine world. Maybe some gods are more accepting than others, and this could create new conflicts or alliances.
The OC could be a descendant of a minor god or goddess that hasn't been explored much in the Percy Jackson universe. For example, a descendant of Hecate. This would give the OC powers related to magic and the ability to interact with the supernatural in unique ways that tie into the existing mythology.
Time guns can fit in by creating new plot twists. Imagine a scenario where the time guns are stolen from a secret vault. Reyna is suspected at first, but Percy believes in her innocence. They team up to find the real thief. As they search, they discover that the time guns have a connection to an ancient prophecy in the Percy Jackson universe. This not only adds mystery but also deepens their relationship as they work together.
In Percy Jackson fanfiction, the seven deadly sins can be incorporated as powerful forces or entities. For example, they could be ancient evils that the demigods have to combat. This adds a new layer of danger and conflict to the already complex world of Percy Jackson.
In some fanfictions, mortals might see Percy's scars as marks of a troubled past. They could be curious about how he got them, but Percy would likely be cautious about revealing the truth, which often involves his demigod adventures and battles. For example, a mortal might notice a long, thin scar on his arm and assume it was from a fight, not realizing it was from a monster encounter.
Percy would probably use his powers over water to his advantage. Maybe there are large lakes or rivers in the Jurassic times and he can control the water to create barriers or distractions against the dinosaurs.
