The mystery aspect. Since it implies there's more to Chat Noir than what's obvious, it creates a sense of intrigue. Readers are likely to be drawn in to find out what these hidden elements are.
In this fanfiction, it could potentially reveal new relationships for Chat Noir. He might form unexpected alliances or have complex interactions with other characters that add a whole new dimension to his story. It could also delve into his powers, perhaps showing some undiscovered aspects or limitations.
Lisa is another favorite. Her power of seeing the connections between things allows for some really creative storytelling in fanfiction. She can be used to uncover secrets, predict events, and her relationships with other capes are always ripe for exploration.
One interesting aspect is the exploration of character relationships in greater depth. For example, the fanfiction might focus on the friendships or rivalries between different Transformers that were not fully explored in the original series. It can also introduce new storylines that are more character - driven, like a Transformer dealing with an internal conflict about their purpose or loyalty.
Plagg, Chat Noir's kwami, would surely be important. He could offer advice to Chat Noir on how to deal with Gabriel. Maybe he has some knowledge about Gabriel that he hasn't shared before. Also, Adrien could be a significant character in the background. Since he is Gabriel's son, his presence or the threat to his well - being could influence the confrontation. And don't forget Nooroo, the kwami of the Butterfly Miraculous that Gabriel uses. He could be a wildcard in the confrontation, perhaps trying to break free from Gabriel's control.
Well, one common plotline is the exploration of alternate powers for the characters. For example, a character might develop a new aspect to their existing power that changes the power dynamics in the story. Another could be the formation of unexpected alliances. Maybe a hero and a villain find common ground and team up for a specific goal.
Another difference is the pacing. Fanfiction writers can take their time with a story, building up tension and character development at their own pace. In the official storylines, there may be time constraints due to production schedules or the need to keep the story moving forward quickly to maintain audience engagement. Fanfiction can also experiment with different writing styles, which might not be possible in the more standardized official storylines.
Most likely Ladybug would be involved. Since Chat Noir has a special relationship with her, any kiss she's involved in would be of great interest to him.
A must - read Chat Noir and Ladybug fanfiction is 'Love in the Shadows'. It has a really interesting plot where their love is tested in unexpected ways. 'The Parisian Miracles' is also great as it has a lot of action and at the same time explores the relationship between the two heroes. And 'The Secret of the Miraculous' is a fanfiction that keeps you on the edge of your seat as it reveals some secrets about their powers and how it affects their relationship.
One possibility could be that an akuma's power goes wrong and instead of attacking Chat Noir in a normal way, it turns him into a baby. Ladybug is then left to protect this baby Chat Noir while also trying to find a way to reverse the transformation. She might have to take him to Master Fu for help, all while hiding him from Hawk Moth who could potentially use this situation to his advantage.
