Starkiller in fanfiction, not the 'lemon' kind, is usually portrayed as a character with great potential in the Force. He might be shown as being in a struggle against the Sith or trying to find his own path. His relationships with other Star Wars characters like Vader or Luke are often explored, showing his place in the Star Wars universe.
Starkiller is the central character in this story. He's likely to be a character with unique abilities and a significant role in the Star Wars universe.
Yes, there might be. The concept of crossing over Naruto with Starkiller is quite interesting. Fanfiction writers often like to blend different fictional universes. Some might be inspired by the unique abilities of Naruto and Starkiller and create a story where they interact, perhaps in a new adventure or even in a battle against a common enemy.
A more detailed fanfiction could involve Starkiller being lost in time and ending up in Ahsoka's era. At first, they are suspicious of each other, but as they learn about the common threats they face, they start to trust and rely on one another. They could exchange knowledge about the Force, with Starkiller showing Ahsoka some of the unique combat techniques he learned from Vader, and Ahsoka teaching him about the more traditional Jedi ways. This would lead to a deepening of their characters and a great story arc as they work together to protect the galaxy from a looming danger that neither could face alone.
A fanfiction could also explore the idea of Starkiller and Ahsoka meeting in a post - Empire world. Starkiller, having broken free from his Sith past, and Ahsoka, who has seen so much of the galaxy's turmoil, could join forces to help rebuild and protect the newly - emerging peaceful systems. They would have to overcome their differences, as Starkiller has a more aggressive style while Ahsoka is more in tune with the Jedi's peaceful ways. But their shared goal of a better galaxy could bring them together. They could start by training a new generation of Force - sensitive beings, combining their unique teachings to create a more balanced approach to the Force.
A new, mysterious dark side character could also be introduced in the fanfiction to hypnotize Rey. This character could have a unique power that allows them to manipulate minds, and they target Rey because of her strong connection to the Force. They might see her as a threat or a tool to be used for their own evil plans.
Perhaps Starkiller's essence or some of his powers get transferred to Naruto in his own world. Naruto then has to deal with this new power that is very different from chakra. He might be hunted by those who want to control or study this new 'Force - like' power within him. He could also use it to protect his village from new and more powerful threats that are attracted by this strange energy.
If Starkiller became a leader, he would likely bring a very different leadership style. Given his background of being a powerful individual fighter, he might focus on training a small but elite group. This could be effective against the zerg, as a highly skilled force could take on the swarms more strategically.
