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.
The OC's character can be developed by giving it a unique backstory. For example, if the OC is an alien, describe its home planet, its family, and what led it to cross paths with Ben and Gwen. This backstory can influence its actions and decisions throughout the fanfiction.
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).
A common theme is adventure. Since the original show is about Ben having adventures with his alien forms, fanfictions often continue this trend with Gwen also being involved in exciting escapades.
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.
In Ben 10 fanfiction, the romance between Ben and Gwen can be really interesting. It often explores their deep bond that goes beyond just being cousins. Writers might develop their relationship in a way that shows how they rely on each other in different situations, like during battles against powerful enemies. They might also show how their feelings for each other grow over time, starting from a simple friendship to something more profound.
In the fanfiction, the relationship between Ben and Gwen could change in a complex way. The news of the pregnancy might initially cause some tension and fear between them. But as they gradually accept the situation, they start to grow closer. They might start to see each other in a new light, not just as partners in adventure but as life - long partners in raising a child. This could involve a lot of communication, understanding, and compromise as they navigate through this new chapter of their lives together.
In fanfiction, a story about Gwen being pregnant in the Ben 10 universe could take many directions. It might explore how her pregnancy affects her role as a hero. Maybe she has to take a break from fighting aliens and focus on her well - being and the baby's. This could also lead to new character developments for Ben as he has to step up more in her absence.
I really liked 'Ben and Gwen's Team - Up'. This fanfiction focuses on a mission where Ben and Gwen have to work together in a way they haven't before. It delves deep into their personalities, showing Ben's impulsive side and Gwen's more calculated approach. The story is full of twists and turns, and it keeps you on the edge of your seat. It also has some great character development moments for both of them.
One possible plot could be that a new powerful alien threat emerges that neither Ben, Gwen nor Kevin can defeat alone. They have to combine their unique powers and skills. Ben could use his alien forms, Gwen her magic, and Kevin his Osmosian abilities. They start off not getting along well in the team - up, with some bickering about the best way to approach the enemy. But as the situation gets more dire, they learn to trust each other and work in harmony to defeat the foe.
One plot idea could be that Gwen and Lemon have to team up to rescue Ben from an otherworldly threat. They start off not getting along well due to their different personalities, but as they face various challenges during the rescue mission, they learn to understand and respect each other. Another idea is a time - travel story where they go back in time and accidentally change something in Ben's past, and then have to figure out how to fix it before it causes major disruptions in the present. A third plot could be that a new villain targets Gwen and Lemon specifically because of their connection to Ben, and they have to use their combined powers and wits to defeat the villain.
