In 'The Remnant - Magic the Gathering Crossover', a major plot twist is that the magic in Remnant was actually seeded by an ancient Magic the Gathering planeswalker long ago. This revelation makes everyone in RWBY's world question their history and the true nature of their powers.
A really interesting plot twist in 'Magic and RWBY: The Unexpected Alliance' is when the villains of RWBY team up with some of the darker forces in the Magic the Gathering universe. It makes the heroes reevaluate their strategies and forces them to find new allies among the Magic the Gathering characters.
One interesting plot twist could be that Soldier 76's time - traveling abilities (if we assume some extended lore) bring him to the RWBY universe during a crucial moment in a battle. His military tactics and advanced weaponry completely change the tide of the fight. Another could be that in the crossover, Soldier 76 has some sort of connection to one of the RWBY characters' pasts, like he was involved in an event that shaped their family history. And a third plot twist might be that his healing abilities become a key factor in saving a major RWBY character from a near - fatal injury, leading to a new alliance between him and the RWBY team.
One interesting plot twist could be the Keyblade wielders finding themselves in the world of Remnant. They might initially be confused by the Grimm and the Huntsmen system. For example, Sora could mistake a Grimm for a Heartless at first, but then realize it's a whole different kind of threat. Another could be Ruby and her team getting access to the power of the Keyblade. Ruby's scythe skills combined with Keyblade magic would make for an incredibly powerful combination. And perhaps a plot twist where the villains from both universes team up. Salem could see the power of the Heartless and use them to her advantage, while Xehanort might be interested in the power of the Maidens in RWBY.
One cool plot twist could be that in one of the multiverse scenarios, their enemies are actually their allies. This would completely turn their understanding of good and evil on its head and force them to reevaluate their relationships. It could lead to some really intense character development as they try to figure out what this means for their own world.
A really interesting plot twist could be that the Grimm from RWBY are somehow connected to the madness in Arkham Asylum. Maybe they are being summoned by one of the inmates who has some sort of dark magic. Another plot twist could be that a character from RWBY, like Yang, turns out to be related to one of the Arkham Asylum staff in a very unexpected way.
Another interesting plot is a crossover where the Magic The Gathering planeswalkers end up in the Naruto world. They could interact with the ninja clans and get involved in the power struggles. For instance, a planeswalker might team up with Naruto to fight against the Akatsuki, bringing their unique Magic The Gathering powers to the fight. This could lead to all sorts of new strategies and battles.
Sure. One interesting plot twist could be that the five nights are actually a test set up by Ozpin to see how the characters will react under extreme stress. But as the nights progress, things go wrong and real threats emerge that were not part of the original test plan. This would add an extra layer of mystery and danger to the fanfiction, and force the RWBY characters to adapt quickly to new and unexpected situations.
One creative plot twist could be that the once - Grimm - turned - human has memories of their Grimm past. This could lead to internal struggles as they try to come to terms with the evil they once represented. For example, they might have nightmares about their former life as a Grimm and be haunted by the actions they took. Another twist could be that they have special powers related to their Grimm origin. Maybe they can still communicate with Grimm in a way, but use this ability to protect humans instead. It adds an interesting dynamic to the story.
One exciting plot twist could be Spider - Man's web - slinging abilities affecting the Grimm in RWBY. Maybe his webs are able to hold the Grimm in a way that the Huntsmen and Huntresses in RWBY have never seen before. This could change the way battles are fought. Another could be that Spider - Man has to adapt to the world of Remnant, where the rules of physics and combat are different from his own world. For example, he has to figure out how to deal with Dust, the energy source in RWBY, and incorporate it into his fighting style.
One interesting plot twist could be the alchemy of the Fullmetal Alchemist world interacting with the Dust in RWBY. For example, maybe an alchemist discovers a way to transmute Dust into something completely new and unexpected, which throws the balance of power in Remnant (RWBY's world) into chaos. Another could be a character from RWBY somehow getting involved in the Philosopher's Stone plot of Fullmetal Alchemist, leading to a race between different factions in both worlds to either obtain or destroy it.
One popular plot twist could be the SI (Self - Insert) character having a unique ability that completely changes the power dynamics in RWBY's world. For example, if they have the power to nullify Grimm instantly, it would turn the fight against the Grimm on its head. Another could be a plot twist where the SI character discovers they are related to one of the main characters in a way no one expected, like being a long - lost sibling of Ruby. It adds a whole new layer of drama and connection to the story.
