The 'jiraiya vs pain' in RWBY fanfiction could be a battle of wits as much as a battle of powers. Jiraiya is a very experienced ninja, and Pain has his own ideology - driven powers. In a RWBY setting, the battle could be affected by things like Dust, the special energy source in RWBY. Jiraiya might be confused by this new element at first, while Pain could try to incorporate it into his attacks. It would be a clash of two different power systems and fighting styles.
Well, in this fanfiction, Velvet is often portrayed as a character with great potential. When facing off against CRDL, her unique abilities can really shine. For example, her photography - based Semblance can be used in very creative ways during the fight, perhaps to create distractions or even to enhance her own combat skills in some unforeseen ways.
I'm not entirely sure specifically, but generally in a 'rwby vs the meta fanfiction', it could involve the RWBY characters facing challenges that are outside the normal scope of the RWBY world. For example, they could be up against foes or situations that are created by the meta - nature of fanfiction, like self - aware characters from other works invading their world. Or it could be about the characters breaking the fourth wall to address issues that are important to the fan base.
The 'rwby sun vs adam fanfiction' could be a great exploration of character dynamics. Sun is often seen as a friendly and somewhat goofy character, but he's also a capable fighter. Adam, on the other hand, is a complex and often menacing figure. The fanfiction might delve into how Sun's light - hearted nature contrasts with Adam's dark and brooding personality. It could also show how their respective relationships with other characters, like Sun's with Blake, influence the fight. Maybe Sun is fighting not just for himself but also to protect Blake from Adam's wrath, adding an extra layer of motivation and emotion to the battle.
One main theme is often cooperation. Since it involves two different groups of characters, they usually have to learn to work together despite their differences. For example, the RWBY characters with their unique semblances and the RVB characters with their military tactics need to combine their strengths.
In RWBY fanfiction, the Weiss vs Winter fight can be a display of their different combat styles. Weiss is more about grace and precision with her Glyphs, while Winter, being more experienced, has a more refined and perhaps harsher style. Their fight could also explore their complex relationship as sisters.
In the 'rwby tai vs raven fanfic', it might focus on the backstories that led them to this point of conflict. Tai might be fighting for the sake of his family or his ideals about protecting Remnant. Raven, on the other hand, could be in the fight for her own self - interest or to protect secrets she holds. The fanfic could also show how their relationship, whether it was once friendly or always strained, affects the way they fight each other.
There might be a fanfic where the technology from RVB is introduced to the world of RWBY. Like, Caboose could accidentally bring some of the Freelancer's advanced weaponry to Remnant. This would cause a stir as the RWBY characters try to figure out how to use or counter this new technology. It could lead to some humorous moments as the RVB characters try to explain the functions in their own, often-confusing ways.
One interesting plotline could be a friendly sparring match that turns into a real test of skills and teamwork for both RWBY and JNPR. Maybe there are unexpected alliances formed during the fight.
It's really hard to say who would win. Jiraiya has his Sage Mode which gives him enhanced strength, speed, and perception. But Pain has the Rinnegan which allows him to use powerful abilities like the Six Paths techniques. In the RWBY fanfiction context, it might depend on how well they adapt to the RWBY world. If Jiraiya can quickly figure out how to use Dust to his advantage, he might have an edge. But if Pain can use his powers to disrupt the balance of the RWBY world, he could also come out on top.
