Ruby would be a great character to feature. Her energetic and adventurous nature would make her reactions to the strange Portal world really interesting. She'd probably be eager to explore and figure out how the portals work.
In my opinion, Jaune Arc could be a really good character to feature. He's always trying to prove himself and a new, powerful human weapon could be the key to his growth as a warrior. The weapon could have some sort of self - training or guiding mechanism that helps him become a better fighter. Oscar Pine is another one. Since he's the new host of Ozpin, a human weapon could play a role in his journey. Maybe it's a weapon that can help him better control Ozpin's power or it could be a weapon that was once used by Ozpin in a past life.
Yang Xiao Long is another excellent option. Given her brawler - like fighting style that already utilizes her gauntlets, fanfiction could explore even more powerful versions of her gauntlets. And adding greaves could give her new ways to attack and defend, especially in close - quarters combat. For example, she could use the greaves to perform powerful kicks in combination with her punches from the gauntlets.
Ruby is a great choice. Her innocent and energetic personality can be really interesting when combined with an animal form or when interacting with animals. Blake would also be good as she has a connection to the Faunus, which are part - animal. You can explore her dual nature further in an animal - themed fanfic. Weiss could be portrayed as having a special bond with a magical ice - based animal, like a snow leopard.
Definitely Yang. Her strength and fearless attitude would be really interesting in a gaming context. She could take on powerful opponents head - on. Weiss, too. Her strategic mind and combat skills would make her a valuable player in any game within the fanfic. Also, her ability to use Dust could add an extra layer of complexity to the game scenarios.
Ruby is often a popular choice. Her naivete and wide - eyed wonder make her reactions interesting. Whether it's reacting to a new place or a strange object, she has a charm that draws readers in.
Ruby is very popular in RWBY workout fanfiction. Fans like to write about her using her speed during workouts, like running drills at super - fast speeds. Yang's strength training is always a hit, as she's often seen as the muscle of the group. Blake has a lot of potential in fanfiction workouts, for example, her ability to climb and move silently can be translated into unique workout scenarios. Weiss is also well - liked, as her formal training background can lead to some complex and sophisticated workout routines in fanfiction.
Ruby is often a popular choice. Her innocent yet powerful nature can be really interesting when placed in the Starcraft universe. Yang is also popular as her combat skills and fiery personality can create some intense storylines. Another popular character is Weiss, with her noble background and powerful Glyph abilities that can be reimagined in the context of Starcraft.
Blake is also a favored character to feature. Her stealth and combat skills, along with her complex backstory, can be well - integrated into stories involving Ultraman. She could use her skills to support Ultraman in battles against common enemies, or they could have some really deep conversations about justice and equality while fighting side by side.
Yang is also well - liked. Her strength in combat and her fiery personality can create interesting dynamics in a multi - player fanfiction. She can be both a tough fighter and a great source of comic relief.
Beast Boy from Titans is also a common character in these fanfictions. His ability to transform into different animals can create some really cool and unique scenarios when combined with the RWBY universe. For example, he could transform into a Grimm - like creature for a strategic advantage in a fight.
