One common theme is the underdog's journey. Usually, the main character starts as a nobody in the mauler wrestling world and has to fight against all odds to reach the top.
One great mauler wrestling story is 'The Mauler's Ascent'. It's about a young wrestler in a small town who overcomes numerous challenges to become a renowned mauler wrestler. He battles against tough opponents and also has to deal with internal doubts.
In some versions, it could be a former ally who has been corrupted. This character, once on Ahsoka's side, has now turned against her due to some external influence or personal greed. Their knowledge of Ahsoka's strengths and weaknesses would make them a formidable opponent, and they could be the one to cause her death.
Naruto would probably be very curious about Ahsoka's Jedi powers. He might constantly ask her to show him how her lightsaber works. Ahsoka, on the other hand, would be interested in Naruto's ninjutsu and his ability to use chakra in different ways. They would likely start off with a bit of friendly competition, showing off their skills to each other.
Well, determining Ahsoka's age in the novel can be a bit tricky. It often depends on the timeline and events of that particular story. Sometimes it's explicitly mentioned, but other times you might have to do some detective work within the narrative to figure it out.
The Ahsoka novel is indeed canon. It fits within the established framework and narrative of the Star Wars universe and contributes to the overall lore.
Darth Vader is often featured. Given their past connection, it creates a very interesting dynamic in the fanfiction. Another character could be Maul. His own complex relationship with the dark side can interact in various ways with Ahsoka's journey into darkness.
