One possible storyline could be Percy using his demigod powers in a new way to lead the gang. For example, his ability to control water could be used to create diversions during heists or to protect the gang's territory from rival groups. Another could be Percy having to deal with the moral implications of leading a gang while still holding onto his heroic values. Maybe he forms the gang to protect the demigod community from a new, more dangerous threat that the traditional Camp Half - Blood can't handle alone.
He might become more assertive and decisive. Normally, Percy is a bit of a reluctant hero, but as a gang leader, he'd have to make quick decisions to protect his gang. He could also become more secretive, as gang activities often need to be kept under wraps.
Another aspect could be Percy building his own team in the chaos realm. He would have to choose members who can adapt to the unpredictable nature of chaos. This could include demigods with unique abilities and even some minor gods who are disillusioned with Olympus.
Another factor is that it fills in the gaps that the original books might have left. Maybe there were some relationships or events that fans wanted to see more of. Fanfiction, especially those about the gang, can explore these areas. For instance, how the gang deals with new campers or how they handle secrets within the group. All these aspects contribute to the popularity of Percy Jackson gang fanfiction.
In this fanfiction, Percy could also have to make difficult decisions about the future of the chaos realm. Should he keep it separate from the mortal and godly worlds? Or should he try to merge it in some way? His choices would have far - reaching consequences for all the realms involved.
There's 'Percy Jackson and the Gang in the Underworld'. In this fanfiction, the gang embarks on a journey to the Underworld, full of action - packed scenes and some really creative interpretations of the afterlife. It's a thrilling read for any Percy Jackson fan. The author also does a great job of developing the relationships between the gang members further.
If Percy Jackson is leading the Chaos Army in fanfiction, one thing that could occur is that he forms alliances with other powerful forces. Given his reputation and the fact that he has friends in many different places, he could convince other groups to join his cause. He might also face challenges from within the army, as some members may not be used to his leadership style. However, Percy would likely overcome these challenges by proving himself through his actions and by showing that his way of leading is the best for the overall success of the Chaos Army.
Spiderman would probably be the better leader. He has more experience in handling the kinds of threats that are common in a city environment. He also has a strong sense of responsibility towards the people in his city.
Some fanfics in the Percy Jackson gang genre could explore the backstories of the characters in relation to the gang concept. Maybe Percy was unknowingly part of a gang - like group in his early days at Camp Half - Blood. It could show how his skills and personality were shaped by this early 'gang' experience, which could be really interesting to read about.
One common theme is friendship. Just like in the original Percy Jackson series, the characters in the HS Gang fanfics rely on their friendships to get through tough situations. Another theme is the struggle between the mortal high school life and the world of Greek mythology they are often connected to. For example, they might have to balance homework with fighting monsters.
