Yoda and Iroh are often used in crossovers. Yoda is known for his great wisdom and connection to the Force, while Iroh has his own deep understanding of the elements and spiritual knowledge in the Avatar world. Their interactions could be really fascinating, like Yoda learning about tea from Iroh and Iroh learning about the Force from Yoda. Another popular crossover is between Darth Maul and Azula. Both are very skilled and somewhat unhinged antagonists.
In these fanfics, Obi - Wan Kenobi and Toph are also popular for crossovers. Obi - Wan's calm and collected nature could contrast with Toph's brash and earthy personality. They could learn from each other in combat and in terms of character growth. Additionally, Rey from Star Wars and Katara from Avatar The Last Airbender could be an interesting pairing. Rey's discovery of her powers could be related to Katara's development of her water - bending skills.
Anakin Skywalker and Aang are quite popular. Anakin's journey from a young Jedi to Darth Vader could be paralleled with Aang's growth as the Avatar. They both have a lot of power and face internal struggles. Also, Luke Skywalker and Korra could be an interesting crossover. Luke's hero's journey could be compared to Korra's as she overcomes various challenges in her world.
Zuko is extremely popular as well. His complex character arc, from being a villain - like figure to a hero, is very engaging. People love to see his transformation and how he overcomes his inner demons and the expectations of his family and nation.
Aang is often a popular choice. Genderbending him can lead to some really interesting storylines, like how a female Aang would handle being the Avatar in a male - dominated world of bending. Another popular one is Zuko. Changing his gender can add a whole new layer to his character arc, especially his relationship with his father and his journey of self - discovery.
Harley Quinn and Rey could be a popular crossover. Rey is a strong female character in Star Wars, and Harley Quinn has a very distinct personality. A fanfic could explore how Rey's determination and Harley Quinn's chaos - loving nature would interact, maybe they team up to take on a group of bad guys in a very unorthodox way.
It's hard to say for sure, but Anakin Skywalker could be extremely powerful. His natural Force abilities combined with the power of bending, say firebending, would make him a formidable opponent. He could use the Force to enhance his bending skills and his lightsaber combat skills.
One interesting crossover could be the use of the Force in the Avatar universe. Imagine a Jedi being able to bend elements using the Force, or an Avatar having a connection to the Force. Another idea could be characters from Star Wars traveling to the world of Avatar and having to adapt to the bending abilities. For example, a Sith lord might try to use his dark powers to control the benders, creating a new kind of conflict.
Sakura from Naruto is often included in these crossovers as well. Her skills as a healer and her growth as a strong female character can add depth to the crossover stories. She could potentially learn new forms of healing from the Avatar world or teach her own medical ninjutsu to Avatar characters.
Han Solo and Commander Riker are also often crossed over. Han's roguish charm and piloting skills combined with Riker's military strategy and charisma make for an exciting pairing. They could be on a mission together, trading quips and sharing their different experiences from their respective universes. Another popular crossover is between Luke Skywalker and Spock. Luke's connection to the Force and his journey to become a Jedi, compared to Spock's logical Vulcan upbringing, offers a lot of room for character development and interesting interactions in fanfiction.
One popular storyline often involves the main character navigating complex relationships within the harem. For example, Aang might have to balance his duties as the Avatar with the emotions and needs of different characters in the harem. Another common plot is the development of individual relationships, like how Zuko could form a unique bond with a member of the harem while also dealing with his own redemption arc. Some fanfics also focus on the cultural differences between characters in the harem, which adds depth to the relationships and the overall story.
Luke Skywalker and Marty McFly are often popular choices. Luke's heroism and Jedi powers combined with Marty's relatable and adventurous nature can make for great stories. Another popular combo is Darth Vader and Doc Brown. The contrast between the dark, powerful Sith Lord and the eccentric inventor can create a lot of drama and humor in a fanfiction.
Luke Skywalker is often a popular character in Star Wars avatar fanfiction. His journey from a farm boy to a Jedi Knight is inspiring, and in avatar fanfiction, he can be re - imagined in different scenarios. For example, he could be an avatar in a parallel universe where the Empire won, and he has to find a way to restore the balance. Another popular character is Darth Vader. His complex backstory and his transformation from Anakin Skywalker make him a fascinating subject for fanfiction. Avatars related to him could explore his inner conflict between the light and the dark side further.
