What could be a great plot for a Ben 10, Gwen and Kevin crossover fanfiction?

An evil alien warlord from a far - off galaxy could be a great main villain. He could have an army of powerful alien creatures at his command. He might be after the Omnitrix, Gwen's magic book, and Kevin's Osmosian powers to become all - powerful. His forces could be causing chaos across the universe, and it's up to Ben, Gwen, and Kevin to stop him.

Well, perhaps Kevin kidnaps Gwen because he wants to use her as a bargaining chip against Ben. He might think that by having Gwen in his control, he can force Ben to give up the Omnitrix or something valuable. Another possibility is that Kevin has some sort of grudge against Gwen specifically, maybe related to her magical powers that he either fears or envies.

One possible plot could be that they face challenges in their relationship due to the unexpected pregnancy. They might struggle with how to balance their superhero duties and preparing for a new life. For example, they could worry about protecting their unborn child from their enemies.

One common theme is friendship. Kevin and Gwen's friendship is often explored, showing how they support each other. Another theme is growth. Kevin's growth as a character, whether it's in terms of his powers or his personality, is frequently a part of these fanfics.

A really interesting fanfic is 'Beyond the Omnitrix: Gwen, Kevin and Ben'. This fanfic takes the story to a whole new level by exploring what lies beyond the use of the Omnitrix. It shows how Gwen's magic, Kevin's powers and Ben's alien forms can combine in unexpected ways. The character interactions are well - written, making it a must - read for fans of the trio.

Well, a good fanfic in this regard needs to capture the essence of the characters. Gwen is smart and powerful with her magic, Kevin is the tough guy with his unique powers, and Ben has his Omnitrix. A fanfic that plays on their relationships, like their friendly rivalries or how they support each other, is great. And of course, an exciting adventure or mystery that they have to solve. It could be something related to an alien threat or a new magical mystery. For instance, if the fanfic has them exploring an ancient alien ruin where Gwen's magic is the key to unlocking the secrets, but they also need Kevin's strength and Ben's alien forms to overcome the traps, that would be really engaging.

Well, it could be about how Ben and Gwen adjust to their new roles as parents. Maybe they face challenges like protecting the baby from villains who might want to use the baby's special powers (assuming in the fanfic world the baby has some).

The plot could center around the OC having a unique item that attracts the attention of both Ben and Gwen. This item might be a key to an ancient power or a device that can manipulate time. As they all try to figure out what the item is and how to use it, they face challenges from other alien races who also want the item. Ben uses his various alien forms to battle these foes, Gwen uses her intelligence and magic to solve the mysteries related to the item, and the OC provides insights based on its own knowledge of the item's origin.

Well, a plot twist could be that right after they kiss, they find out that there is a time - travel related issue. Like, their kiss has sent them to a different dimension where they have to work together to get back home while dealing with their new - found feelings. It could also be that the kiss was witnessed by a jealous ex - partner of either Gwen or Kevin, and this ex - partner then tries to break them up in really devious ways. Maybe the ex - partner spreads false rumors about one of them, which causes a rift between Gwen and Kevin.

Obviously, Ben could be the one to save Gwen. With his Omnitrix, he has all kinds of powers at his disposal to take on Kevin and rescue Gwen. He knows both of them well, so he would be highly motivated to stop Kevin and bring Gwen back safely.
