Well, a great Gwen 10 fanfic idea might be a time - travel story. Imagine Gwen going back in time to when she first discovered her powers and having to relive those experiences while also trying to change something for the better. Or perhaps a story where Gwen has to use her powers in a completely different way than she's used to, like in a world where magic works differently. There could also be a fanfic that focuses on Gwen's relationships with her family members, like a heart - to - heart conversation with her grandpa Max that reveals some long - hidden secrets about their family's powers.
One idea could be a story where Gwen and Greymatter team up to solve a complex scientific mystery that requires both Gwen's combat skills and Greymatter's intelligence. They could be in a race against time to stop an evil scientist from using a dangerous invention.
Another plot could be that a mysterious camper arrives at the camp where they work. David and Gwen suspect something strange about this camper and start to investigate together. As they dig deeper, they not only solve the mystery but also discover new things about each other and their feelings for one another.
A possible plot is that there is a threat in both worlds at the same time. Gwen and Harry have to team up, with Gwen using her alien powers and Harry his magic. They travel between the two worlds, trying to find the source of the threat. Gwen's Ghostfreak form could be used to spy on the enemies in the Harry Potter world without being detected easily.
One plot idea could be that Gwenom and Spider - Gwen have to team up against a new powerful villain who is causing chaos in their city. They initially have some differences in their approaches to fighting crime, but as the story progresses, they learn to work together effectively.
Well, you could write a fanfiction about Gwen's past. For example, how she felt when she first discovered her powers. Was she scared? Excited? You could also write about her relationships within the family, like her interactions with her parents or other relatives. And don't forget about her friendships. Maybe she has a falling - out with one of her friends and then has to work hard to fix it in the fanfiction.
Another concept could be a time - travel fanfiction. Gwen somehow travels back in time to when Duncan was a younger and more vulnerable version of himself. She helps him through a tough time, and he sees her in a new light. This new - found connection culminates in a tender kiss.
A great plot could involve Spiderman getting injured in a fight and Gwen having to take on his responsibilities for a while. She could struggle with the pressure but also gain a new respect for what Spiderman does. Or perhaps there's a plot where an old enemy of Spiderman returns and targets Gwen to get to him. This would lead to some intense rescue scenes and a strengthening of their bond. Also, a story where they find an ancient artifact that has powers related to their spider - abilities and they have to figure out how to use it without it falling into the wrong hands.
One idea could be that Spider Gwen discovers a strange lemon - themed villain in her city. The villain uses lemon - scented gases to disorient people. Gwen has to figure out how to combat this unique threat while also dealing with her normal life as a superhero and student. Another plot could involve a lemon - based experiment gone wrong that gives Gwen new powers related to lemons, like the ability to shoot lemon - juice webs. Or perhaps there's a lemonade stand in her neighborhood that is actually a front for a criminal operation, and Gwen has to investigate it.
A fanfic where Spider Gwen discovers a new dimension and has to adapt to the strange new world while also trying to find a way back home. This could involve her making new friends and facing different kinds of threats.
Perhaps Gwen discovers she has some latent magical ability during her pregnancy, which is awakened by the life growing inside her. This could cause a stir in Camelot as magic is feared. Merlin then has to step in to help Gwen control her powers and keep it a secret from those who would harm her. Also, Arthur could be faced with the dilemma of how to protect Gwen and the baby from the anti - magic sentiment in the court.
