Maybe Percy gets betrayed by his friends in the fanfiction. This could lead him to become dark as he loses trust in those he once cared about. He might then start using his powers in more aggressive and self - serving ways.
Perhaps it's one of Percy's former friends who has turned against him. This friend could be jealous of Percy's powers or has been influenced by some dark force. Their actions and taunts could be what drives Percy to become dark, making them the main antagonist in the story.
One change would be his interests. Instead of just focusing on Greek mythology and his demigod adventures, he now has an additional passion for dragons. He might start spending his free time reading dragon lore.
One idea could be that Percy uses his unique experiences in battles to teach combat strategy in a school for demigods. He could share real - life examples of how he overcame monsters and use those to illustrate key points in strategy.
Well, if Percy Jackson were to become an Avenger in fanfiction, there would be some interesting dynamics. For one, his loyalty to his demigod friends might conflict with the Avengers' way of doing things at times. But his ability to think on his feet, which he developed from all his quests, would help him adapt quickly. And his relationship with the other Avengers, like maybe a friendly rivalry with Thor over who has better control over elemental powers, could be a great plot point.
His old friends from Camp Half - Blood like Annabeth could be his allies. She would support him through the transition of becoming a god. Grover too, as his long - time friend, would be there for him. Also, some of the minor gods who have always been on good terms with Percy, like Hestia, might offer their help and guidance as he steps into his new role as a god.
I think the nature spirits might support Percy. Since Percy has a connection with water and nature in general, they would see him as a more benevolent leader compared to the current gods. Also, the mortals who have been saved by Percy in the past would probably be in favor of him becoming the king of gods. They believe he would use his power to protect them and make their lives better, rather than just for the gods' own amusement or self - interest.
I'm not entirely sure who 'Percy' is as the Titan in this specific dark fanfiction without more context. It could be a unique character created by the author with their own set of powers and characteristics within the fictional world of that fanfiction.
In fanfiction, 'Dark Percy is not evil' could be because the author wants to explore a different side of the character. Maybe they see potential for a more complex personality that is often misjudged as evil due to his dark appearance or actions that are misinterpreted. It gives a chance to show that there are reasons behind his actions that are not malicious.
There could be a wise old monster who acts as Percy's mentor. Maybe a female monster who becomes Percy's love interest. And of course, there would likely be some villainous monsters who oppose Percy's new existence and try to harm him.
