One reason could be that in the fanfiction, Ben is getting a lot of attention from other characters. Maybe the story has Ben in a romantic relationship with someone else, and Gwen, who has a close bond with Ben in the original series, feels left out. It could also be that the fanfiction portrays Ben in a heroic light without much focus on Gwen's role, making her jealous of the spotlight he's getting.
Well, 'Star - Crossed with Ben Tennyson' is a must - read. It has an interesting take on the relationship, with the reader character coming from a different world and how they and Ben deal with the cultural differences. And 'Love Among the Aliens' is really good too. It shows a more mature side of the relationship between Ben and the reader, dealing with issues like trust and loyalty in a very engaging way.
It could strain their relationship. Gwen might start acting cold towards Ben because of her jealousy. She may avoid him or be less cooperative when they are together in the story.
One great 'Ben 10 Ben x Gwen Fanfiction' is 'Parallel Bonds'. It explores their relationship in an alternate universe where they have to work together against a new kind of enemy. The story is full of action and also delves into their emotional connection.

To write a good 'Ben Tennyson x Reader' fanfiction, you need to focus on their relationship development. Start with how they meet and gradually build up the chemistry between them. Make use of the Omnitrix and Ben's alien forms in the story to add some action and excitement. For instance, the reader could be in danger and Ben has to transform into one of his aliens to save them. And don't forget to add some emotional depth to their interactions.
Power and responsibility is also a big theme. Ben has to handle the powers of his alien forms responsibly, especially when dealing with aliens. In many fanfics, there's also the theme of discovery. Ben discovers new things about the aliens, their cultures, and their abilities. For example, he might learn a new power from an alien that he can use in a different way. There's also the theme of cooperation, where Ben and the aliens work together to achieve a common goal, like saving a planet or stopping a powerful enemy.
In a 'Ben 10 Ben X Young Gwen Time Travel Fanfic', the possibilities are endless. They could travel to the future first and see a dystopian version of their world where the bad guys have won. This spurs them to go back in time to prevent it from happening. Along the way, they might meet their future selves who give them clues or warnings. Their time - traveling could also cause some unforeseen consequences, like creating alternate timelines. For example, if they change one small event in the past, it could lead to a completely different Ben 10 universe in the future. So they have to be very careful with their actions during their time - traveling journey.
One common theme is growth. Both Ben and Gwen grow as individuals and in their relationship. Another theme is friendship, as their bond is often a central part of the stories. Adventure is also a big theme, since they are from the Ben 10 universe and usually go on exciting adventures together.
One idea could be a crossover where Naruto and Gwen end up in the same dimension. They might initially be at odds, with Naruto being all about ninjutsu and Gwen having her alien - based powers. But as they face a common enemy, like an evil alien - ninja hybrid, they learn to work together. Their different fighting styles and outlooks on life would make for an interesting dynamic.
