Another great plot could be about Nero in the RWBY universe. Nero's Devil Bringer arm could be a source of both mystery and power in Remnant. Maybe he teams up with Weiss to figure out the origin of his arm's power, which could be related to some ancient Remnant magic. This could lead to a journey across Remnant, exploring different kingdoms and uncovering secrets that were long forgotten. Along the way, they would face various Grimm and other villains.
One interesting storyline could be Dante from Devil May Cry visiting Remnant (the RWBY world). He might get involved in the fight against the Grimm. His combat skills and devilish powers would be a great addition to the battles. For example, his ability to use different weapons like Rebellion and Ebony & Ivory could make for some epic fight scenes against the powerful Grimm. He could also interact with the RWBY characters, like teaching Ruby some new sword techniques, as he is a master swordsman.
A possible storyline could involve Vergil from Devil May Cry ending up in RWBY's world. Vergil, with his thirst for power, might be intrigued by the power of the Maidens in RWBY. He could initially see them as a means to gain more power for himself. But as he interacts with the RWBY characters, especially Blake, who has her own complex past and views on power, he might start to question his own motives and eventually turn into an ally against a greater threat, like Salem.
Ruby and Dante would be an interesting pairing. Ruby with her innocent and positive attitude could contrast with Dante's more laid - back and devil - may - care nature. They both are great leaders in their own ways and could learn a lot from each other in combat. Dante could show Ruby some new sword techniques and Ruby could show Dante the power of Aura and how it can be used in battle.
A 'devil may cry 4 crossover fanfiction' could be really interesting. It might involve characters from 'devil may cry 4' interacting with characters from other universes. This could lead to some really unique storylines. For example, Dante from 'devil may cry 4' could team up with a character from a different action - adventure game. The fanfiction could explore different power combinations and how they would work together in battles.
A crossover with the Castlevania universe would also be cool. Dante could find himself in Dracula's castle, facing off against classic Castlevania monsters while also dealing with his own demonic foes. It would be interesting to see how he interacts with the Belmonts.
I think Vergil and Pennywise could also be an interesting combination. Vergil is very much about power and control. He would likely approach Pennywise with a more calculated mindset. Pennywise, on the other hand, would try to break Vergil's stoicism by getting into his head and exploiting his fears. It would be a battle of wills, with Vergil trying to cut through Pennywise's illusions and Pennywise trying to make Vergil doubt himself.
One idea could be that the characters from RWBY end up in the Devil May Cry world and have to team up with Dante to fight off a new type of demon that is attracted to the unique Aura energy of the RWBY characters. Another could be a crossover where Nero and Ruby exchange their weapons for a short time and learn from each other's fighting styles. Maybe Yang could also have a friendly sparring match with Vergil to compare their strength and swordsmanship skills.
One plot idea could be a crossover where the characters from RWBY have to team up with Dante from Devil May Cry to fight a powerful demon that has somehow made its way into the RWBY universe. This would bring in Dante's combat skills and his devilish powers to the mix.
One common theme is the exploration of power. In both Devil May Cry and RWBY, power is a central aspect. Fanfictions often explore how characters from different universes would compare in terms of power. For example, Dante's devil powers vs Ruby's scythe - wielding skills.
One idea could be that Pennywise from 'it' somehow enters the world of 'Devil May Cry'. Dante could mistake Pennywise for a particularly grotesque demon and engage in a battle. Pennywise, with his shape - shifting abilities, would constantly change forms to try and deceive Dante. Another plot could involve the characters from 'Devil May Cry' being lured into Derry by Pennywise's illusions. They then have to fight their way out while also dealing with the psychological warfare that Pennywise is known for.
One possible plot could be that Dante and Bayonetta are both drawn to a powerful demonic artifact that has the potential to either destroy or rule the underworld. They initially clash, thinking the other is after it for the wrong reasons. But as they face off against powerful demons sent to retrieve the artifact, they realize they need to work together. Dante's wild and carefree style combined with Bayonetta's sassy and powerful moves would make for some epic fight scenes as they fight their way through hordes of demons.
One idea could be a crossover with the Bayonetta series. Dante and Bayonetta could team up to fight a common, powerful demon. Their different fighting styles would make for some epic battles and interesting interactions. For example, Dante's flashy swordplay combined with Bayonetta's acrobatic and magical combat.
