In fanfiction, there's no set rule. It's a realm of creativity. There could be a fanfiction where Obi - Wan is related to Padme's father through a prophecy or a magical force - related event. Or perhaps in a parallel universe - type fanfiction, their relation is part of a major plot twist. So, simply put, it's possible in the wild world of fanfiction.
One example could be a story where Luke discovers Obi - Wan had a daughter and they team up to face a new threat. Maybe she has some hidden powers that are crucial in the battle.
In most Star Wars canon, there's no relation between Obi - Wan and Padmé's father. However, in fanfiction, the possibilities are endless. Some fanfics might create a connection for the sake of a more complex plot. Maybe Obi - Wan could be involved in some secret mission related to Padmé's family before her birth, which could be construed as a form of connection to her father.
The 'obi wan kenobi novel' is all about Obi - Wan Kenobi. It likely tells of his journey, his growth as a character. Maybe it starts with his situation post - Order 66, how he has to adapt to being alone and hunted. It might also introduce new characters that cross his path and how they influence his decisions. It could describe his training and how he passes on his Jedi knowledge in a very subtle way. His battles, not just the physical ones but also the mental and moral ones, are probably a big part of the novel as well.
Some fanfictions might have a plot where Padme's father was involved in a past event that Obi - Wan is now investigating. As Obi - Wan delves deeper, he realizes there are more connections between them than he thought. For example, Padme's father might have been a key figure in a war that Obi - Wan is now trying to understand better, and this connection could change the way Obi - Wan views Padme and his role in her life.
Well, in some fanfictions, there might be a situation where Obi - Wan and Padmé's father are born under similar circumstances. For example, they could both be born during a time of great upheaval in the galaxy. This similarity in their birth times could be used by the fanfiction writer to create a connection between them later in life. Or perhaps Padmé's father was born with some special ability that Obi - Wan later discovers and it becomes a crucial part of the story.
In a Dark Jedi Obi - Wan Kenobi fanfiction, his relationship with Anakin could be drastically different. Instead of being a mentor, he could be a rival. They might compete for power within the Sith hierarchy. Obi - Wan's appearance would also change. His robes could become darker, and there could be a more menacing look in his eyes. His connection to the Force would take on a darker hue, using it more for personal gain and domination.
The graphic novel about Obi - Wan Kenobi could cover different parts of his life. It may show his training as a Jedi, his experiences with his master, and how he developed into the wise Jedi we know. It might also feature his interactions with Anakin Skywalker during Anakin's early days as a Padawan, and the influence he had on Anakin's growth.
Imagine Obi - Wan Kenobi meets a kind and strong - willed woman from a peaceful planet. She is drawn to his wisdom and calm presence. Obi - Wan, in turn, is intrigued by her different perspective on life. They start to communicate more often, and gradually he realizes he has feelings for her. However, his commitment to the Jedi way makes him hesitant. He must decide between following his heart and staying true to the Jedi teachings.
One great fanfiction idea could be Obi - Wan secretly guiding Ezra Bridger in his Jedi training during the events of Star Wars Rebels. Maybe he appears as a Force ghost only Ezra can see at first. This would add an interesting dynamic as Ezra is trying to find his way as a Jedi without a proper master on hand.
