Another theme is the mystery of his potential. Even as a baby, Luke has the potential for great power in the Force. Fanfictions often explore how those around him sense this and what they do about it. They might worry about whether he'll turn to the dark side like his father or become a great Jedi hero.
Protection is a common theme. Since he's a baby and the son of Anakin Skywalker, many fanfictions focus on how various characters like Obi - Wan, Beru, and Owen protect him from the Empire. For example, Obi - Wan might use his Jedi skills to hide Luke's presence.
The theme of hope also frequently appears. In a galaxy filled with darkness after the fall of the Republic, Luke represents a new hope. Fanfictions might show how his very existence gives people on Tatooine or other planets the will to resist the Empire, even when he's just a baby.
A common theme is self - discovery. Since the character is reborn as Luke, they have to figure out who they are in this new identity. Another theme is power and responsibility, just like in the original Star Wars. They have to handle the power of the Force and the responsibility that comes with being Luke Skywalker.
One common theme is his longing for adventure. Since he's stuck on Tatooine at first, a lot of fanfiction explores his yearning to break free and see the galaxy.
One common theme is forbidden love. Since he is a Jedi, Jedi code forbids attachments which can make a relationship with someone a forbidden love. Another is redemption through love, where the love of another character helps Luke overcome some of his inner demons or challenges.
One common theme could be the shock and adjustment. Just like in real - life pregnancy stories, Luke would have to come to terms with this unexpected state. Another theme might be the reactions of his friends and enemies. They would likely be very surprised and have a range of responses from support to disbelief.
There could be a fanfiction where baby Luke Skywalker is visited by a mysterious Jedi in his dreams. This Jedi gives him some sort of premonition or a message about his future. It could be a Jedi who was friends with his father and is trying to guide Luke from afar, even at this young age.
One common theme is protection. Since they were in danger as babies, many fanfictions focus on how they were kept safe.
One common theme is gender - role reversal. Since Luke is female in these fictions, it often explores how she challenges the male - dominated Jedi culture. For example, she might face different expectations from the Jedi Council.
A third theme could be the exploration of the Force. His injury might lead to new insights about the Force. Maybe he discovers a new way to use it to heal himself or he has visions related to the Force while in pain, which then changes his understanding of the Force in a deeper way.
If baby Luke time - travels to a post - apocalyptic future in the Star Wars universe, he could be the key to rebuilding the Jedi Order. His very existence could inspire the survivors to start anew. They might look at his pure connection to the Force as a sign that there is still hope for a better future, and they would protect and train him to become a great Jedi, changing the fate of the galaxy once again.
Often, there could be themes related to adventure and how their relationship evolves during their various escapades in the Star Wars universe. For example, they might support each other in a more intimate way during battles or dangerous missions. Another theme could be the acceptance of their relationship within the Star Wars community in the fanfic, dealing with any potential prejudices or challenges that come their way.
