How does the story develop in the 'Ben 10 Gwen gets the Omnitrix' fanfiction?

One possibility is that the story could explore how Gwen's personality changes when she has the Omnitrix. She might become more confident or more responsible. Also, there could be new villains who are attracted to the Omnitrix now that Gwen has it. She would then have to face these threats and protect the Omnitrix from falling into the wrong hands.

In this fanfiction, Gwen might use the Omnitrix to fight new and unexpected villains. She could transform into various alien forms and discover new powers within each transformation.

One possible antagonist could be an alien bounty hunter who wants to take the Omnitrix from Gwen for his own purposes.

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.

He'd become more versatile. With the Omnitrix, he'd have to learn about different alien cultures and powers, which would make him more open - minded.

It's not common at all. Most fanfiction tends to follow the more positive and popular pairings or storylines within the fandom. The idea of Ben getting Gwen pregnant is rather controversial due to their family relation in the source material. Writers usually prefer to write about things that are more in line with the general mood and values of the fan community, which doesn't really include this kind of rather odd and potentially uncomfortable scenario.

He could have a unique personality trait, like being extremely shy but when he transforms using the Omnitrix, he becomes super confident. For example, if he transforms into a big, strong alien, his normal timid self disappears and he becomes a fearless leader in battle.

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.

Well, Ben is obviously one of the main characters as the story is centered around him and the Omnitrix. Gwen might also be a main character as she often plays an important role in Ben's adventures, providing support or using her own magical abilities to help out. Grandpa Max could be another main character, offering his wisdom and experience to guide Ben through various situations.

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.
