In fanfiction, Dark Luke Skywalker's character can develop in various ways. Sometimes he starts off as a conflicted figure, gradually succumbing more and more to the dark side. His power grows as he delves deeper into Sith teachings or his own dark interpretations of the Force.
In Clone Wars fanfiction, Luke might start off as a bit of a fish out of water. He's used to a different era of the galaxy, but as he gets involved in the Clone Wars, he starts to adapt. His Jedi skills become more refined as he faces different challenges than he did in his own time.
When traveling to the future, Luke could become more desperate. Facing a world in chaos or a new, powerful enemy, he'd have to quickly adapt and find solutions. This would make him more willing to take risks and use powers in ways he hadn't before. His view of the Force might also expand as he encounters new forms of it in the future.
Typically, 'Dark Luke Skywalker' fan fiction portrays his transformation in different ways. Some show it as a result of being betrayed by his friends or the Jedi Order. He then starts to question the light side teachings. His powers might become more aggressive and less about defense. He may also start to have a different view on power and how to use it, seeing the dark side as a means to achieve his new goals. For instance, in a particular fan fiction, Luke is frustrated with the slow progress of the Jedi in bringing peace, so he turns to the dark side to enforce his own version of order.
In many Star Wars fanfictions, a 'Dark Luke Skywalker' is a fascinating concept. It often shows a different path Luke could have taken. Maybe if he had given in to the dark side during his training or due to some great loss. This version of Luke can be extremely powerful and menacing, with a different set of abilities compared to his canonical self.
Luke's friends from the light side could also be important. Characters like Leia, Han Solo, or Chewbacca. Their reactions to Luke's turn and their attempts to bring him back would be significant aspects of the story. There could also be new characters created specifically for this novel, perhaps some Jedi who were thought to be dead but are actually in hiding and oppose Luke's new path.
In some fanfictions, Dark Sonic starts off as a purely evil force. But as the story progresses, he begins to regain some of his old self. Maybe through the love and friendship of his comrades, he slowly comes back to his senses.
Another aspect of his development in fanfiction is his relationship with his family. In some stories, he might reconcile with his father, Goku, or his mother, Chi - Chi. This can be a major turning point in his character arc, as it can bring out the more human and emotional side of Dark Gohan that was perhaps overshadowed by his darkness before.
Luke could be developed through his interactions with the Jedi Council during the Clone Wars in the fanfiction. Maybe he disagrees with some of their decisions, which forces him to question his own beliefs about the Jedi Order. This internal conflict would add depth to his character as he tries to find his own path within the Jedi ideology of that era.
He might interact with respect and a bit of nervousness. After all, the Jedi Council is a very important body in the Jedi world.
His character would develop in a very different direction. He'd be more independent and self - reliant. No longer bound by the strict Jedi code, he could explore the darker aspects of his personality. He might become more cynical and worldly. His skills with a lightsaber could be used more for intimidation and self - defense in the cutthroat pirate world. His view of the Force might also change, seeing it as a tool to gain power and wealth rather than just a spiritual guide.
