Another possibility is that they are rivals at first. Maybe there's a competition among the gods for the most beautiful creation. Apollo, with his skills in art and music, creates magnificent works, while Britomartis has her own unique creations related to the Cretan landscape. As the story progresses, they come to respect each other's talents and end up collaborating on a grand project for the gods.
For Apollo, you can emphasize his confident and sometimes over - confident nature. Show his love for music through his actions, like constantly humming a tune or being drawn to any musical event. For Britomartis, highlight her connection to nature, perhaps she's always surrounded by gentle animals or has the ability to make plants grow with a touch.
Well, it could be about an adventure where Pwrcy and Apollo go on a journey through a magical realm. Maybe they are on a quest to find a lost artifact that has the power to save their world.
One possible plot could be that Naruto, through some sort of magical or dimensional rift, ends up in a world where Apollo exists as a female. Naruto, with his determination and kind heart, befriends fem Apollo. They could go on adventures together, Naruto teaching her about his ninja world and she in turn sharing her knowledge of her own realm. Maybe they have to team up to fight a common enemy that threatens both their worlds.
Well, it could be about Percy and Apollo becoming friends in an unexpected way. Like, Apollo is in a situation where he loses his godly powers temporarily and Percy helps him out. During this time, they bond over their shared experiences of being different from regular humans. They start to understand each other's strengths and weaknesses, and form a strong friendship.
It could be about Cave Johnson somehow being involved in the Apollo 18 mission. Maybe he's a secret backer providing unique technology. For example, his company's experimental propulsion system could be used on the Apollo 18 spacecraft.
One possible plot could be that Kushina Uzumaki, with her strong will and unique abilities from the Naruto universe, somehow crosses paths with Apollo from Greek mythology. Apollo, being the god of many things like music, prophecy, and the sun, could be intrigued by Kushina's fiery spirit. He might offer to help her with some power she has been struggling to control, and in the process, they develop a deep bond.
One possible plot could be that Naruto, as Apollo's daughter, discovers her divine heritage in a world that has no prior knowledge of Greek gods. She might struggle to control newfound powers related to light, prophecy, and music, which are associated with Apollo. And she could use these powers to protect her village from new and powerful threats.
Well, it could be about Apollo losing his powers completely and Percy trying to help him but failing. Maybe Percy feels sad because he can't do much for his friend. And Apollo is in despair as he is no longer the powerful god he once was.
One possible plot could be Percy's adventures in the world of the Greek gods as the brother of Artemis and Apollo. Maybe he has to use his unique skills, perhaps some sort of special powers related to his divine siblings, to solve a problem in Olympus. For example, he could be the key to resolving a conflict between two powerful godly factions.
One plot twist could be that Apollo is actually secretly working with the Titans against the other gods. This would completely change his role in the story and create a lot of conflict. Another could be that he loses his powers and has to rely on mortals to regain them during the 'Clash of the Titans'.
