Another plot could be a time - travel story within the 'the outsiders' universe. For example, a character travels back to the events before the big rumble and tries to prevent some of the tragedies from occurring. This would involve a lot of character interaction and changes to the original storyline.
A love story between a greaser and a Soc that goes beyond the typical rivalry could also make for great fanfiction. Maybe they team up to bridge the gap between the two groups, facing opposition from both sides but remaining determined to make a difference.
One idea could be an OC who is a new kid in town and tries to bridge the gap between the Greasers and the Socs. They might use their unique perspective from a different place to show both groups that they're more alike than they think.
A great plot for Young Justice Outsiders fanfiction could involve a crossover with another DC team or universe. Maybe the Outsiders accidentally end up in an alternate dimension where they have to team up with unlikely allies to get back home. This would introduce new dynamics and challenges for the characters.
One idea could be to explore what would happen if Ponyboy became a successful writer earlier. He could use his writing to change the perception of the Greasers in the town.
One idea could be an OC with a unique power, like the ability to manipulate sound waves. They could join the Outsiders and use their power in unexpected ways during battles, for example, creating sonic illusions to confuse enemies. Another plot could involve an OC who is from a different dimension and has to adapt to the Young Justice Outsiders' world while also bringing some of their own world's knowledge and technology. Or perhaps an OC who has a personal vendetta against a villain that the Outsiders are also after, and they initially clash with the team but then learn to work together.
One idea could be that the Outsiders are called in to help the Young Justice team when a new, powerful and mysterious villain emerges. This villain has a unique power that neither team has faced before, forcing them to combine their skills and resources.
Perhaps the Outsiders' town is secretly a gateway to one of the realms in the 'Percy Jackson' universe. The Outsiders get involved when strange creatures start coming through the gateway. They team up with Percy and his friends to close the gateway and in the process, they learn about each other's worlds and form unlikely friendships.
One plot idea could be that Sodapop and Ponyboy go on a road trip together. They face various challenges on the road, like car troubles and meeting some interesting characters. This would allow for a lot of character development and some really sweet moments between them as they rely on each other.
One idea could be exploring the unspoken stories of the ranch hands. Maybe there's a hidden love affair between two of them that has to be kept secret due to the social norms of 1923. Another could be focusing on how a young character dreams of leaving the ranch and going to the big city, but faces many obstacles. And a third idea could be a mystery plot where strange things start happening on the ranch and the characters have to figure out what's going on.
One idea could be Android 21's struggle to fit into a world that fears her. She has to prove that she's not a threat and tries to make friends. Another could be her discovery of new powers and how she uses them for good. Maybe she teams up with other characters to fight a common enemy.
One idea could be Vampirina making new friends in the human world who are initially scared but then come to understand her. For example, she could join a school club and have to prove that she's not a threat.
