Luke Skywalker could be crucial in some fanfictions. Even if he's dead in the official movies, in fanfiction he could appear as a Force ghost guiding Ben. His wisdom and the connection he has with Ben could be a driving factor in Ben's journey to awaken. Another important character could be Kylo Ren's mother, Leia. Her love for her son might be a powerful force in pulling him back from the dark side.
Obviously, Ben himself is one of the most important characters. His growth and awakening are at the core of the story. Rey could also be very important as she might play a role in his awakening, either as a friend, a mentor, or just someone whose actions inspire him.
One interesting idea could be exploring Ben's internal struggle in more depth. Maybe his journey to fully embrace the light side and overcome the dark influences that have been plaguing him. It could also involve new relationships he forms during this awakening process, like with characters who help him see a different path.
There are several important characters in Ben Solo's story. His parents, Han Solo and Leia Organa, were significant as they were part of the Rebel Alliance and his family. Snoke was a major figure as he groomed Ben to be Kylo Ren. Rey was also very important. Her connection with Ben through the Force was a key element. Their interactions led to his transformation and redemption. Also, Luke Skywalker had an impact as he was Ben's uncle and his actions had consequences on Ben's path.
Luke Skywalker is also a very popular choice. He could be a mentor - like figure to Ben, teaching him about the Force while Ben shows Luke his alien forms and the powers they possess. Yoda could also be a great crossover character. His wisdom and connection to the Force could be really interesting when combined with Ben's more impulsive and action - based nature from the Ben 10 series.
The main characters in Star Wars The Force Awakens story include Rey, a tenacious scavenger on Jakku. She has a mysterious past and a growing connection to the Force. Finn, formerly known as FN - 2187, is a stormtrooper who defects from the First Order. He brings a different perspective to the story. Kylo Ren, a powerful user of the dark side of the Force, is full of rage and conflict. His relationship with his family and his pursuit of power are central to his character. And BB - 8, the adorable droid, is crucial as it has a part of the map to Luke Skywalker. These characters interact and their fates are intertwined throughout the story.
The main characters include Rey, a strong - willed scavenger. Finn, the former stormtrooper. And Kylo Ren, the dark side follower.
Poe Dameron is an important character as well. He is a skilled pilot for the Resistance. There are also some older characters from the previous Star Wars movies that make appearances or are mentioned, which tie the new story to the original trilogy.
A sentient droid that has its own unique understanding of the Force. It could be a droid that was created by an ancient Jedi or Sith as an experiment. This droid would have abilities that no other droid has, like being able to sense Force users from a distance or even manipulate the Force in a small way.
Perhaps Sasuke could be like a Sith - like character in this fanfiction. He is drawn to the dark side of the Force due to his own inner turmoil and thirst for power. His Sharingan could have some interesting interactions with the Force - related abilities, like being able to sense the presence of other Force - users more acutely.
Definitely Ben Tennyson himself. His ability to transform into various aliens would add a whole new dynamic to the Star Wars universe. Also, characters like Darth Vader would be great. Imagine the confrontation between Ben in one of his powerful alien forms and Vader with his lightsaber and the Force. Another interesting character could be Yoda. Yoda's wisdom and his unique view of the Force could interact in an interesting way with Ben's more action - based alien powers.
In a crossover fanfiction, Ben 10 characters could find themselves in the Star Wars universe through some sort of interdimensional rift. Ben, being the main character, would be in the center of the action. His alien forms would be quite a shock to the Star Wars characters. For instance, his Heatblast form could be seen as a powerful new type of weapon by some factions. Gwen's magic would add an interesting element as it's different from the Force. She could teach some of the Jedi or Sith about her unique form of power. Grandpa Max could help establish diplomatic relations between the different groups in the Star Wars universe. They would all have to learn about the Force, lightsabers, and the complex politics of the Star Wars galaxy while also using their own abilities to survive and thrive.
