Leia Organa would be a great addition. She's a strong leader in the Rebel Alliance. Her leadership skills and diplomatic abilities could really help the Rebels crew in their fight against the Empire. She could also form a great friendship with Hera.
Definitely Darth Vader. His presence would create a lot of tension. He could be on a mission to hunt down the Rebels crew, and it would be a battle of wits and strength as they try to outmaneuver him.
Ahsoka Tano would be an excellent addition. She has a rich history in the Star Wars universe, from the Clone Wars to her later appearances. Her wisdom and combat skills could be a great asset to the Rebels in a crossover. She could also provide a link between different eras of the Star Wars story.
Naruto and Ezra would likely be main characters. They are both young heroes on a journey of self - discovery.
Sabine Wren would be a great character to include. They have a connection in the Star Wars Rebels series, and their interactions could be further explored in fanfiction. Ezra Bridger is also a good choice. His journey and his relationship with Ashoka could be developed more. Another character could be Bo - Katan Kryze. Her Mandalorian ways and her goals could clash or align with Ashoka's, creating interesting storylines.
Well, the Sith Lords in general are popular in these crossovers. Their use of the dark side of the Force and their power - hungry nature can create some intense storylines. And from other universes, characters like Captain Kirk could be included. His exploration - based mindset would clash with the Empire's more controlling nature. It could lead to some great moments of conflict and cooperation as he tries to navigate the Empire's complex politics and power dynamics.
A great idea for an Echo x Star Wars Rebels crossover fanfiction would be that Echo has some sort of encrypted data in his cybernetic enhancements that could be crucial for the Rebels. The Rebels have to figure out a way to access it without harming Echo. This could lead to a lot of character - development moments as they get to know Echo and his past better, and Echo gets to adapt to the Rebels' way of doing things.
Light Yagami from Death Note. The mind games between Light, who has the Death Note, and Jotaro with Star Platinum would be intense. Light would try to find a way to outwit Star Platinum's power while Jotaro would be trying to stop Light's plans.
Well, Sabine Wren from Star Wars Rebels would be a great candidate. She has a strong connection to Mandalorian culture already. She could interact with Din Djarin from The Mandalorian. They could exchange stories about their experiences with Mandalorian traditions and perhaps even team up to fight against the Empire.
Definitely Luke Skywalker. He could cross paths with Iden and they could have some interesting ideological battles. Leia Organa would also be a great addition. Her strong leadership and rebel spirit could contrast with Iden's Imperial upbringing. And of course, Han Solo. His roguish charm could make for some entertaining interactions with Iden.
Ezra Bridger is quite popular. He has a complex character arc in Star Wars Rebels, and fanfiction writers like to explore his further growth, his relationships, and what he might do after the events of the show. Another popular one is Darth Vader. His iconic status in the Star Wars universe makes him a favorite. Writers often write about his past, his thoughts, and his interactions with other characters.
A fanfiction could revolve around Echo's memories. He has flashbacks to his time in the Clone Wars that end up providing valuable insights for the Rebels. For example, he remembers a weakness in a type of Imperial droid that the Rebels are currently facing. This not only helps them in battle but also makes the Rebels see Echo as a valuable asset.
