Well, in sans crossover rwby fanfiction, a cool concept is the combination of magic systems. Sans has his own kind of 'magic' in his world, and RWBY has the Dust and Aura. How these two different power sources interact or clash can make for some exciting plot points. Also, the cultural differences between the two universes can lead to some interesting storylines. Sans coming from a very different kind of world might have a hard time understanding some of the social norms in RWBY's world, and vice versa.
Some concepts involve the idea of Sans being a mentor - like figure in RWBY. His knowledge of his own world's combat and his ability to think on his feet could be valuable to the RWBY characters. He could teach them new ways to approach battles, especially when it comes to facing unexpected enemies. And the aesthetic of combining Sans' simple but iconic look with the more elaborate and colorful designs of RWBY characters can also be really appealing in these fanfictions.
One interesting concept could be how Sans' unique abilities from his original game would interact with the RWBY universe. For example, his teleportation might be a new and unexpected skill in RWBY battles. Another concept could be the character interactions. Sans' laid - back personality could create some really fun and comical exchanges with the more serious or energetic RWBY characters like Ruby or Weiss.
One interesting concept could be Itachi's Sharingan abilities in the RWBY universe. His visual prowess might be used in unique ways during battles against Grimm. For example, he could use the Sharingan to predict Grimm movements more accurately, similar to how he reads his opponents in the Naruto universe.
Well, Link could be transported to RWBY's world during a time of great crisis, like when Salem is about to make a major move. His courage, which is a big part of his character, could inspire the RWBY team to face their fears more directly. And his knowledge of ancient magic from Hyrule might be the key to unlocking some hidden secrets in RWBY's world. For instance, there could be a long - lost relic in RWBY's world that only Link's magic can reveal, and this sets off a chain of events that involves both his quest and the RWBY characters' goals.
In RWBY Earth Crossover fanfiction, a cool concept is the way the Grimm would be perceived on Earth. Maybe the military would try to study them, thinking they are some new kind of bio - weapon. Also, the Huntsmen and Huntresses could become like superheroes on Earth, with people being in awe of their powers and skills.
One interesting concept could be the combination of Kirby's unique powers, like inhaling enemies and stealing their abilities, with the combat styles and semblances in RWBY. For example, Kirby might gain Ruby's speed semblance and use it in a creative way during battles in the RWBY world.
One interesting concept could be the clash of different powers. In RWBY, characters have unique abilities like semblances, and the Reaper has its own set of death - dealing powers. A crossover might explore how these powers interact when the two universes collide. For example, how would Ruby's speed and scythe - wielding skills compare to the Reaper's? Another concept could be the meeting of different character personalities. RWBY characters are often young and idealistic, while the Reaper is a more menacing and mysterious figure. Their interactions could lead to some really engaging storylines.
One interesting concept could be crossovers with other well - known anime. For example, combining RWBY characters with Naruto characters can create unique battle scenarios and character interactions. Another concept might be a crossover with a fantasy world like Middle - earth from 'The Lord of the Rings'. RWBY characters could face new challenges and form alliances in that setting. Also, a crossover with a superhero universe would be exciting, seeing how RWBY's Huntsmen and Huntresses would interact with traditional superheroes in terms of powers and ideologies.
One interesting concept could be the combination of Archer Emiya's combat skills with the unique abilities in RWBY. For example, his archery skills might interact in new ways with the Dust - based weapons of RWBY. Another concept could be the cultural clash between Archer's origin world and the world of RWBY. His more serious and battle - hardened nature might contrast with the sometimes more light - hearted or inexperienced characters in RWBY, leading to interesting character development moments.
In Naruto sans fanfiction, there might be unique story arcs. For instance, the story could focus on a mission that was never mentioned in the original Naruto series. This mission could lead to the discovery of a new hidden village or a long -lost ninja art. Also, the fanfiction might explore different family backgrounds for the characters, like Naruto having a different father figure which could completely change his personality and growth.
One interesting sans crossover fanfiction could be where Sans from Undertale crosses over with the world of Harry Potter. He might use his unique abilities like teleporting to surprise the wizards in Hogwarts. Another could be a crossover with the Pokémon world, where Sans teams up with Pikachu. Maybe he'd use his bone attacks along with Pikachu's electric shocks to battle villains.
A third concept could be exploring different universes. Fanfiction could depict a scenario where the RWBY universe and the Halo universe (where Noble 6 is from) collide, creating a completely new world. This new world could have its own rules, like a mix of Dust and advanced Halo technology. Characters would have to adapt to this new environment, and it could lead to a lot of interesting plot twists.
