A great plot could be that they time travel to a post - apocalyptic future. There, they find remnants of their friends and family but also discover that their actions in the present led to this desolate future. They then have to travel back and make different choices. Also, they could time travel to a time when magic was at its peak in their world. Artemis might struggle with the new rules and powers that exist in this time, while Wally has to deal with the slower pace of life before modern technology. Together, they could learn a lot about themselves and their relationship as they navigate this strange time.
Well, they could time travel to a historical event, say the Trojan War. Wally could use his super speed to get a better understanding of the strategies, while Artemis uses her archery skills to blend in. And in the process, they accidentally change something that has a ripple effect on their present. Or perhaps they travel to a time when the Justice League was first formed and meet the younger versions of their mentors. This could lead to some really interesting character interactions and also some self - discovery for Wally and Artemis as they see how far they've come.
One idea could be that they go on a secret mission together outside of the team. Maybe they are sent to infiltrate an enemy base where they have to rely on each other's skills more than ever. Wally's super - speed could be used for quick escapes and distractions, while Artemis' archery skills are crucial for taking out guards from a distance.
Their relationship could deepen. As they face the unknowns of different time periods together, they would rely on each other more. For example, if they end up in a dangerous past or future, they would need to protect one another. This would make them more aware of their feelings for each other.
One idea could be that Percy and Artemis travel back to the time of the Titans' rule. They could try to find a way to prevent the Titans from ever rising, which would change the entire future of the demigod world. Maybe they meet young versions of the gods and have to convince them to work together against a common threat that the Titans pose even before the first war.
One plotline could be the challenges they face in preparing for the baby. Maybe they have to deal with their superhero duties while also getting ready for the new arrival. Another could be how their friends and family react to the news. Some might be overjoyed, while others could be worried about the implications for their superhero lives.
One possible plot could be them dealing with a new villain that specifically targets married superheroes. They would have to use their combined skills and the strength of their marriage to overcome the threat.
Well, a plot could revolve around Wally getting into trouble and Kuki being the one to rescue him. For example, Wally accidentally stumbles into a time - traveling portal and Kuki uses her smarts to figure out how to bring him back. Or perhaps they both find a magical object that binds their fates together and they have to learn to co - exist with this new connection, which eventually leads to a strong bond between them.
Another plot could involve their cultural differences, if any, in the fanfiction. For example, how they celebrate different holidays or traditions and how that affects their married life. They might have to find a balance between their own heritages and create new family traditions.
A plot could be where Batman discovers that Artemis has a unique connection to an otherworldly power source that some bad guys are after. They go on a quest to protect this power source. For example, it could be a magical amulet that Artemis has unknowingly been in possession of. Also, they could have a story where they train together. Batman teaches Artemis some of his detective techniques and in return, Artemis shows Batman some new combat moves. This could strengthen their bond and lead to them being a more effective team against threats.
One idea could be Madara traveling back to the era of the Sage of Six Paths. He could try to change the very foundation of ninjutsu, which would create a whole new timeline. Maybe he would attempt to gain the power of the Sage for himself much earlier in history.
One plot idea could be Naruino traveling back in time to prevent a great disaster in their world. Maybe a powerful enemy once defeated them in the past, and by going back, they can change the outcome. Another could be traveling to the future to see how their actions in the present have affected the world. For example, they might find that their current choices led to a utopia or a dystopia.
