Another reason could be related to ideology. Maybe Pre Vizsla believed Maul's actions or teachings were leading the Death Watch astray from its original goals. He could have considered Maul too radical or not in line with what he thought the group should stand for, so he took the drastic step of killing him to set things right according to his view.
One interesting plotline could be a battle that takes place in an alternate universe where Anakin and Obi - Wan have different allegiances from the start. Maybe Anakin is a Sith Lord right from the beginning and Obi - Wan has to face his former apprentice in a more cut - throat battle.
Anakin and Obi - Wan could fit into a Marvel fanfic if they were part of a multiverse - spanning story. The Marvel universe already has concepts like the multiverse. They could be brought in as representatives of a different kind of power (the Force). Anakin's emotional and sometimes unpredictable nature could create interesting dynamics with the more stable Marvel heroes. Obi - Wan could act as a mediator between the two universes, using his knowledge of the Force and his diplomatic abilities to navigate the complex relationships in the Marvel world.
Well, Anakin is often very well - written. His internal conflict between the light and dark side can be explored in great detail. His complex relationship with Obi - Wan, from being a beloved apprentice to a bitter enemy, gives a lot of room for character development. Writers can show his journey from a hopeful Jedi to a conflicted individual on the verge of falling to the dark side.
The impact of Pre Vizsla and Bo Katan on Mandalore in fanfiction is multi - faceted. Pre Vizsla's rule under Death Watch brought a dark cloud over Mandalore. He was more concerned with his own power and the goals of the separatist movement. Bo Katan, being a Mandalorian at heart, saw the destruction this was causing. She took it upon herself to change the situation. In fanfictions, she might use her charisma and her connection to the traditional Mandalorian clans to rally support against Pre Vizsla. Her efforts could range from diplomatic negotiations to full - blown battles. In the end, she was often portrayed as the one who restored peace and prosperity to Mandalore, undoing the damage caused by Pre Vizsla.
Well, it could be really chaotic. Maybe Anakin and Obi - Wan would be mistaken for new superhumans in the Marvel universe. Their lightsabers would be seen as some sort of high - tech weapons. They might end up getting involved in the Avengers' battles, either as allies or foes depending on how the story is written. Anakin's power could be compared to that of Scarlet Witch, and Obi - Wan's wisdom might be on par with Doctor Strange's.
In the Clone Wars, Pre Vizsla and Bo Katan had a complex relationship. Pre Vizsla was the leader of Death Watch, a Mandalorian group with a somewhat extreme view. Bo Katan was also part of the Mandalorian world. Initially, she was associated with Death Watch under Pre Vizsla's leadership. However, their paths diverged as Bo Katan started to question some of the more violent and separatist actions of Death Watch. She realized that Pre Vizsla's methods were not in the best interests of Mandalore as a whole. Their relationship was one of loyalty that turned into a rift as Bo Katan sought a more noble and just path for Mandalore.
There may not be mainstream, widely - publicized fanfictions with Obi - Wan gagged. But some independent writers might have created stories around this concept. It could be that in a story, Obi - Wan is gagged during a diplomatic mission turned hostile. His captors want to silence him to gain an advantage in negotiations. This could lead to a complex plot where his friends have to use their wits and skills to free him and resolve the diplomatic crisis.
Well, Obi - Wan Kenobi has shown time and again his ability to adapt to different opponents. He defeated General Grievous, a formidable foe. Pong Krell, on the other hand, was consumed by his own dark desires. When it comes to a fight between them, Obi - Wan's use of the Force for defense and offense, his lightsaber skills which are refined over years of training, and his wisdom in combat situations would make him the victor. He can sense his opponent's moves and counter them effectively, something Krell's overconfidence might not be able to handle.
