A possible plot could be that the heroes are injured in a fight far from their usual haunts. So, they have to rely on each other and their wits to get back to safety while being injured. They might have to hide from civilians as well as any potential threats. This could lead to some really intense and emotional moments between them as they support each other through the pain.
Another idea is that their kwamis, Tikki and Plagg, have to find a way to heal them. Since the Miraculous connection is so strong, perhaps the kwamis can use their own energy or some hidden power within the Miraculous to start the healing process. But it comes at a cost, like the kwamis becoming temporarily weakened themselves, adding another layer of tension to the story.
One possible scenario in this fanfiction could be that Ladybug and Chat Noir are injured during a battle with a particularly powerful akuma. Maybe they underestimated the akuma's new abilities. For example, the akuma could have a power that disrupts their Miraculous powers temporarily, making them more vulnerable to attacks. Their injuries might lead to a moment of self - discovery as they realize their limits and have to rely on each other in a different way, like Chat Noir having to protect Ladybug while she tries to figure out a new strategy to defeat the akuma without relying fully on her usual powers.
Well, if the miraculous lucks run out in fanfiction, it could mean a big shift in the story. Characters might have to rely on their own skills and intelligence more. Maybe a hero who was always saved by luck now has to figure out how to save themselves and others without that lucky charm. It could also lead to character development as they learn to deal with hardships.
It could also create a tense situation within the group he belongs to. The others would be worried about him and might split their focus between their ongoing tasks and taking care of Leo. This could lead to some internal conflicts as they try to balance everything. They might argue about the best way to help him or who should stay with him while others continue their mission.
In a Miraculous Ladybug sleepover fanfiction, the characters might have a lot of fun. They could play games like truth or dare, which could lead to some interesting revelations. For example, Marinette might accidentally let slip some of her feelings for Adrien.
Well, in a babysitting assignment in Miraculous fanfiction, the babysitter might have to deal with the kids getting into trouble while also trying to keep their secret identities hidden. Maybe the kids accidentally stumble upon the Miraculous jewels and chaos ensues.
In fanfiction, when Percy meets the old heroes, it could be a really cool adventure. Maybe they would share their tales of glory, and Percy would be inspired. He could also find out about some long - lost secrets of the demigod world that only the old heroes knew. This could help him in his future quests, like facing new and more powerful monsters. The old heroes might also test Percy to see if he's worthy of their knowledge and respect.
One possibility is that the Justice League would be divided. Some members might side with Superman, believing he had a good reason, while others would stand by Batman. This would create a power struggle within the league.
Well, in this fanfiction's final battle, there could be new Miraculous holders joining Ladybug and Cat Noir. They could bring in fresh powers and strategies. Also, the final battle might take place in a completely unexpected location, like inside a digital realm created by Hawkmoth's new power. Ladybug and Cat Noir would have to adapt quickly to this strange environment to win.
She could be in the hospital because of a bad fall during a chase in her Ladybug form. Her classmates might start a fundraising campaign to help with her medical bills. And Chat Noir could be secretly visiting her at night, leaving little gifts by her bedside.
Well, in a Miraculous Ladybug school trip fanfiction, there could be a lot of exciting things. Maybe Ladybug and Chat Noir have to protect their classmates from an akumatized villain during the trip. For example, the villain could target the school bus or the destination they are visiting.
