Definitely Ben Tennyson himself. He's the main character and the one with the Omnitrix. His different alien forms like Heatblast, Four Arms, and XLR8 can add a lot of action and variety to the story.

Well, there's often an OC named Nova. She's usually depicted as having some sort of energy - based powers and being a friend or ally to Ben. Another popular one is Zephyr, who might be an alien - human hybrid with the ability to control the wind. These OCs are popular because they add new elements to the Ben 10 Omniverse.

The main characters are obviously Ben and Kai. Ben is the wielder of the Omnitrix, which gives him the power to transform into various alien forms. Kai is a strong - willed and adventurous character who often gets involved in Ben's escapades.

Gwen is also great as she has her own powers and a complex relationship with Ben. And of course, Kevin, with his unique abilities and his friendship - turned - rivalry - turned - friendship again with Ben.

One interesting storyline could be a female version of Ben having to deal with different alien cultures in the Omniverse in a more diplomatic way than Ben usually does.

Kevin Levin can be a really cool addition. His ability to absorb materials and transform into different forms makes for some exciting action scenes. Also, his complex backstory can create interesting storylines when combined with the reader's character, like if the reader helps him come to terms with his past or something similar.

One possible fanfiction could be about Ben and Kai going on a new adventure in the Omniverse. Maybe they discover a new alien species that is causing chaos in a far - flung galaxy. Ben uses his Omnitrix to transform into different aliens to try and stop the threat, while Kai uses her martial arts skills to fight alongside him.

The main characters are Ben and Kai. Ben is a heroic figure with the Omnitrix, which is a device full of alien DNA that he can use to transform. He is brave and always ready to protect the Omniverse.

It could also be a mad scientist who wants to study Ben's alien forms and the Omnitrix, so they kidnap him to do all sorts of experiments on him.
