A popular theme could be the clash of different power systems. Ben has his Omnitrix which gives him access to various alien powers, while Dracula has his vampiric abilities like super strength, shape - shifting, and mind control. Writers often explore how these powers interact when Ben and Dracula meet.
The theme of redemption might also be present. Maybe Dracula is not entirely evil in the fanfic and is seeking a way to redeem himself. Ben, being the hero, could be the one to either help or hinder this process. It could also be the other way around, where Ben has to make amends for something and Dracula has an unexpected role in it.
One possible fanfic could be one where Ben Tennyson has to face Dracula in a battle that spans different dimensions. Maybe in this fanfic, Ben uses his alien forms in creative ways to combat Dracula's vampiric powers.
In these fanfics, the theme of teamwork is everywhere. Ben and Rook are a team, and exploring how they work together, divide tasks, and combine their skills is a big draw. For example, Ben's brute force with his alien powers and Rook's strategic thinking. Additionally, the theme of facing fears comes up a lot. Both characters have their own fears, and seeing them overcome those in the fanfictions is quite appealing. And of course, the theme of exploring new planets and civilizations, which is a natural extension of Ben's alien - transforming abilities and their intergalactic adventures.
Another popular theme is the mentorship aspect. Fanfics often depict Laura Dreyfuss' character as a mentor to Ben Platt's character or vice versa. This could be in the context of the music industry or just in general life, guiding each other to become better versions of themselves.
Some popular themes in Ben 10 fanfic include exploring new alien forms Ben could transform into, adventures in different galaxies, and team - ups with other characters from the series. For example, a fanfic might focus on Ben using a new alien ability to save a planet from a powerful villain. Another common theme is Ben's growth as a hero, both in terms of his powers and his character.
One popular trope is the 'enemies - to - friends' or 'enemies - to - lovers' trope. Since they come from different backgrounds and might initially have different goals, this transformation in their relationship can be really engaging.
One idea could be that Ben, using his alien forms, has to battle Dracula's minions in a spooky castle. Maybe he teams up with some local vampires who oppose Dracula's tyrannical rule. Another could be that Dracula tries to turn Ben into a vampire to use his alien powers for his own evil deeds.
One popular theme is their relationship development. Fans love to read about how their love grows and overcomes obstacles. Another is adventure, like them going on quests together. For example, in many fanfictions they might go on a magical adventure to save Auradon or the Isle of the Lost.
Obviously, Dracula himself could be the main villain. He has all the classic powers like turning into a bat, super strength, and mind control. He could use these powers to try and take over the world or at least the area where Ben is currently located.
Some 'Ben Ten Fanfic' stories involve crossovers. For instance, a crossover with another popular superhero universe. This could lead to really interesting scenarios where Ben has to team up with different heroes or deal with villains from both universes. There are also fanfics that go back in time to explore Ben's ancestors and how they might have had their own Omnitrix - like devices. Additionally, fan - created stories often look at what would happen if Ben lost his Omnitrix and had to rely on his own natural abilities and wits to fight crime.
Team - up and friendship is also a major theme. Ben, coming from his own universe, has to form alliances with Marvel characters. These relationships develop as they face various threats together. For example, Ben might become friends with Iron Man and learn about technology and responsibility from him.
