They could be rivals at first. Maybe both are vying for a certain position or recognition within the Rebels. Harry might be a new recruit with fresh ideas that threaten Jade's status. However, as they face common enemies, they start to respect each other and eventually become allies. This would make for a great character arc in the fanfiction.
They could be friends. Harry might be someone who helps Jade Vizsla see things from a different perspective. Since Jade is from a warrior - like family, Harry's more laid - back or different cultural background could add an interesting dynamic to their friendship.
There could be many interesting fanfiction ideas involving Harry and Jade Vizsla in the Star Wars Rebels universe. Maybe Harry could be a new character who teams up with Jade Vizsla on a dangerous mission. They might have to face off against the Empire's forces and use their unique skills to survive.
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.
Sabine and Ezra's relationship is a significant part of Star Wars Rebels. They start off as fellow rebels with different backgrounds - Sabine being a Mandalorian and Ezra a Force - sensitive human. As they face various challenges and enemies together, they develop a deep friendship. This friendship is not only important for their personal growth but also for the success of the rebel cause. For example, Ezra learns a lot about different cultures and combat styles from Sabine, and Sabine gains a better understanding of the Force through Ezra.
To create a compelling Vizsla character, start with a strong backstory. Consider their family ties within the Vizsla clan. Maybe they were exiled from the clan for some reason and are now trying to prove themselves. Give them unique physical traits, like a distinctively colored Mandalorian armor. Also, define their moral code. Are they more like the honorable Mandalorians or do they have a darker side? For example, they could be willing to break some rules to achieve a greater good.
In many fanfictions, the relationship between Ezra and Maul is a slow - burn one. At first, Ezra is afraid of Maul, given his reputation as a dangerous Sith. But as Ezra matures in the Force, he begins to understand Maul's motives better. Maul, on the other hand, starts to see Ezra as a kindred spirit in a way, as they both are somewhat outcasts in the grand scheme of the Force - users. This mutual understanding leads to a relationship that is full of tension but also has elements of cooperation and even a strange sort of friendship.
One common theme is redemption. Given Mara Jade's complex backstory in the Star Wars universe, many fanfictions explore her journey towards redemption within the context of the Star Wars Rebels era. This could involve her making amends for past actions or finding a new purpose among the Rebels.
Well, it could be really cool. Maybe the Jedi in Star Wars Rebels could team up with the wizards in Harry Potter. For example, Ezra Bridger could meet Harry Potter and they'd exchange their skills. Ezra could show Harry how to use the Force in a more combat - oriented way, while Harry could introduce Ezra to magic spells that could be used for various things like protection or even transportation in a different way than the Force allows.
Their relationship could develop in a hostile way at first. The Inquisitor is tasked with hunting Ezra, so he would be constantly on Ezra's tail, trying to capture or kill him. Ezra, in turn, would see the Inquisitor as a major threat and fight back with all his might.
One idea could be to have a wizard from the Harry Potter universe accidentally end up in the Star Wars Rebels' galaxy. Maybe they use their magic to help the rebels in unexpected ways, like creating magical shields or using apparition to outmaneuver the Empire's forces.
One great Star Wars Rebels Rex fanfiction is 'Rex's Redemption'. It shows Rex finding his place in the Rebellion after his Clone Wars experiences. Another is 'Rex and Ezra's Bond', which focuses on the relationship between Rex and Ezra Bridger. There's also 'Rex's Leadership in the Rebels' that details how Rex uses his military knowledge to help the Rebels.
