Who are the most likely characters to have a significant role change in 'rwby age swap fanfic'?

Ruby. Since she is the main character, her role and personality can be easily tweaked in alternate universes. For example, she could be more serious or less confident. Blake is also a candidate. Her Faunus heritage could be treated very differently in other universes, which would lead to major changes in her character arc. And then there's Weiss. Her family's influence might be more or less prominent, changing her attitude and actions.

Naruto and Sasuke are very likely. Their contrasting personalities and styles make a clothes swap between them full of potential. It would be a great way to show their differences and similarities in a new light.

Yang and the Yellow Ranger. Yang is a strong and fiery character in RWBY, known for her brawling combat style. The Yellow Ranger in many Power Rangers shows is also a strong fighter. They could bond over their love for a good fight and share tips on how to improve their physical combat skills. Plus, their personalities are quite compatible, with both being bold and confident.

Well, often the power dynamics shift. If a younger character is now older and more experienced, they might take on a leadership role earlier. For instance, Ruby might be in a more authoritative position much sooner than in the original story.

Ruby could be paired with Eragon. Ruby's leadership and combat skills along with her silver eyes' power could complement Eragon's dragon - rider abilities. They could go on quests together, with Ruby's speed and Eragon's dragon - powered flight making them a formidable team.

Roman Torchwick could be a likely candidate in some fanfics. Since he had a connection with Neo in the original series, he might be brought back in a fanfic to brainwash her for his own ends. Another one could be Salem. She's always looking for ways to gain an edge, and Neo's skills would be useful to her if she could control her.

Well, obviously Corvo would be one of the main characters. He would bring his own set of skills, like his combat abilities and stealth techniques. Then, from RWBY, Ruby Rose could be a main character. Her leadership skills and scythe - wielding combat style would contrast and interact with Corvo in interesting ways.

If Ruby and Weiss swap personalities, their relationship could become more competitive. Ruby (with Weiss's personality) would constantly strive to outdo Weiss (with Ruby's personality) in combat and academics. The once harmonious friendship might have more friction as they both try to prove themselves in different ways.

Ben and Gwen are very likely. They are the main characters and have very different personalities and abilities, so swapping them would create a lot of interesting scenarios. Ben is more action - oriented and Gwen is more into magic and knowledge, so seeing them navigate each other's worlds would be exciting.

Naruto himself is very likely to have a significant role. He is the main character of the original series, and his strong will and unique abilities would be crucial in any time - traveling adventure. His determination to protect his friends and the ninja world would drive the plot.
