Perhaps some dark - side influenced beings are her opponents. Given Umbara's dark and shadowy nature, it's possible that there are entities corrupted by the dark side of the Force. They would be extremely dangerous as they could use the planet's dark energy to enhance their powers against Ahsoka.
Her opponents could be the Separatist forces. Umbara was a planet involved in the Clone Wars, so it's likely that battle droids and their commanders would be her foes. They would be trying to gain control of Umbara's resources or strategic locations.
In a 'ahsoka fights on umbara fanfic', the plot might involve Ahsoka facing off against various foes on Umbara. She could be dealing with the unique challenges of the planet, like its dark and shadowy terrain. Maybe she has to battle against local creatures or enemy forces that are using Umbara's environment to their advantage.
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.
A Sith apprentice could be a great antagonist. They might be after the same artifacts or information that the Padawan and Ahsoka are seeking. For example, if there's a powerful Sith holocron, the Sith apprentice would stop at nothing to get it.
In some fanfictions, Ahsoka might help the clones get over Umbara by simply being there for them. She could offer a listening ear, allowing the clones to talk about their traumas. Just her presence can bring a sense of comfort as she is a respected figure among them.
Obi - Wan Kenobi is also a potential character. A body swap with Ahsoka would lead to some comical moments as well as some deep character exploration. Obi - Wan would have to handle Ahsoka's more impulsive nature, and Ahsoka would get to experience Obi - Wan's calm and collected Jedi demeanor.
Anakin Skywalker is a popular choice. Their relationship as master and apprentice in the Star Wars universe provides a lot of material for fanfics. Another popular character is Rex, as they have a history of fighting side by side in the Clone Wars.
Often, amateur writers within the Star Wars fan community write such fanfics. They might be inspired by a specific scene in the series where Ahsoka could potentially scream, and then they build a whole new story around it. Some might be young writers just starting out, using Ahsoka as a character to practice their writing skills and creativity.
Ahsoka might organize group activities for the clones. This could include things like sparring sessions or team - building exercises.

Well, in this kind of fanfic, it could be that Ahsoka is trapped in a collapsing structure while on a mission. She tries to use the Force to hold it together long enough for others to get out. But the strain is too much and she ends up being crushed when the structure finally gives way. Her death could then be a catalyst for her friends to re - evaluate their own lives and fight even harder against the forces of evil.
A plot could be that Barriss discovers a hidden Sith artifact and accidentally gets influenced by it. Ahsoka notices the change in Barriss and tries to help her break free from the dark influence.
