They could go on a journey to discover an ancient Jedi artifact. Katooni's Jedi skills and Pietro's unique abilities would combine to overcome various obstacles like Sith traps and dangerous alien creatures.
In the fanfiction, they might also find themselves in a situation where they have to prevent a powerful dark side force from awakening. Katooni's connection to the light side and Pietro's determination would be crucial in this battle of good versus evil. They'd need to seek out ancient Jedi texts for a solution and enlist the help of other friendly characters in the Star Wars universe.
Ahsoka Tano would be a great character to pair with Katooni. They are both Jedi Padawans and could have some really interesting interactions. They could learn from each other and go on adventures together. Another good option could be Obi - Wan Kenobi. He could be a mentor figure to Katooni and guide her in difficult situations.
One possible plot could be that Katooni and Petro go on a mission to find a lost Jedi artifact. Along the way, they face various challenges like dangerous creatures and Sith traps. They have to use their Jedi skills, with Katooni's ability to sense things and Petro's combat skills, to overcome these obstacles and retrieve the artifact for the Jedi Order.
One potential friend could be Petro. Since they are both younglings at the Jedi Temple, they might bond over their shared experiences in training and their eagerness to become great Jedi. They could support each other in lightsaber duels and in their studies of the Force.
One idea could be to focus on Katooni's training at the Jedi Temple. Show her facing challenges during lightsaber training, like trying to master a difficult form while also dealing with the pressure from her peers. It could explore her relationships with other younglings and how they support or compete with each other.
A great plot might be Katooni having to deal with a dark side - influenced Jedi who has turned against the Order. She has to find a way to either bring this Jedi back to the light or stop them from causing too much harm. Also, perhaps a story where she discovers an ancient Jedi artifact that holds the key to a great power, and she has to protect it from both the Separatists and those within the Republic who might misuse it.
Katooni is a young Jedi. Petro is also a Jedi. In fanfiction, Katooni can be developed by exploring her growth as a Jedi. For example, she could face a personal crisis where she has to choose between the Jedi Code and her own emotions. Petro can be developed by showing his journey to become a more patient and wise Jedi. Maybe he gets into trouble because of his impulsive nature and has to learn from it.
Ahsoka might get involved in a conflict between two warring species. She would use her skills to broker peace and uncover the root of their feud, which could be related to some dark side influence. This would be a great way to show her growth as a character outside the Jedi Order.
Galen could find himself in a future where the remnants of the Empire are making a comeback. He would then have to decide whether to side with the New Republic or try to reform the Empire from within. In a fanfic, this moral dilemma could be explored in great detail, showing his internal struggle as he weighs the pros and cons of each option.
Possible adventures include joining a rebel alliance and fighting against the evil Empire. They might be part of a mission to steal important plans from the Death Star. Or they could get involved in a lightsaber duel with a powerful Sith Lord, testing their skills and courage.
There could be fanfictions that focus on Darth Vader's secret missions during the Clone Wars. Missions that the Jedi didn't know about.
