In a 'Starkiller meets Luke' fanfiction, they could start as rivals. Starkiller, with his powerful Force abilities, might initially see Luke as a threat. They could engage in an epic lightsaber duel. Eventually, they might realize they have a common enemy and team up. For example, against a new Sith Lord. Their combined skills could lead to a great adventure in the Star Wars universe.
It's hard to say. Luke has the potential of the Skywalker bloodline and his training under Yoda and Obi - Wan. But Starkiller was also highly trained by Vader. If they were to face off, it might depend on the situation. In a battle of pure raw power, it could be a draw, but in a battle of strategy, the one who can outwit the other would be more powerful.
One scenario is that they meet on a desolate planet. Luke is there for some Jedi - related mission, and Starkiller has his own agenda. They cross paths and immediately sense the power in each other. Another is that they are brought together by a third party, perhaps a powerful Force - user who wants to see what will happen when these two strong - willed Force - sensitives meet.
They could team up. Maybe they find a common enemy, like a new Sith threat or some powerful dark side entity. Their combined skills in the Force would be formidable. Luke's piloting skills along with Starkiller's raw power in the Force could make them a great duo. They might also learn from each other. Luke could teach Starkiller about the more spiritual and patient side of the Force, while Starkiller could show Luke some new combat techniques he learned from his time with Vader.
One common theme is the clash of different ideologies. Ezra from 'Star Wars Rebels' has his own set of beliefs and Starkiller, with his own backstory, has different views. So, their meeting often leads to interesting debates about right and wrong, power, and loyalty.
One great ezra meets starkiller fanfiction is 'The Unlikely Alliance' on FanFiction.net. It has an interesting plot where Ezra and Starkiller are forced to work together against a common enemy. The story does a great job of exploring their different personalities and powers.
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.
Obviously, Luke Skywalker and Ahsoka Tano are the main characters. Luke is a key figure in the fight against the Empire and in the revival of the Jedi Order. Ahsoka, on the other hand, has a long and complex history within the Star Wars universe, having been Anakin Skywalker's apprentice and later becoming a key figure in her own right.
Anakin, on the other hand, has a complex history. He was once a great Jedi, then fell to the dark side and became Darth Vader. In this fanfiction, he is in a redeemed state or perhaps a state where he is still grappling with his past actions. His presence in the story is crucial as he is the father figure that Luke has been seeking to understand.
