One interesting crossover could be the characters from RWBY using the Assassin's Creed parkour skills. Ruby, with her speed, could be an amazing assassin, running across rooftops in Vale like an Assassin. Another could be the introduction of the Pieces of Eden into the RWBY world, causing chaos as different factions fight over their power.
In a RWBY Assassin's Creed fanfiction, there could be a story where the Assassin's Creed Brotherhood teams up with Team RWBY to stop a greater threat. The Assassins could share their knowledge of ancient weapons and fighting styles with RWBY. Yang could learn some hand - to - hand combat moves from the Assassins. At the same time, the RWBY characters could introduce the Assassins to the concept of Dust and how it can be used in combat, creating a unique blend of the two universes.
One of the most interesting crossovers could be the combination of RWBY's unique combat styles with Assassin's Creed 4's stealth and parkour elements. For example, Ruby's scythe - wielding skills could be adapted to the pirate - themed world of Assassin's Creed 4. She could use her speed and acrobatics to traverse the ship masts and islands in a similar way to how Assassins move in the game.
In some fanfictions, the Isu from Assassin's Creed could be related to the gods in Percy Jackson. Maybe the Isu were the predecessors of the Greek gods. This would lead to a whole new set of adventures as characters from both universes try to figure out their shared history. Also, the hidden blades in Assassin's Creed could be enchanted with Greek magic in the fanfiction, making them even more powerful and useful in battles against both mortal and mythical foes.
Well, a cool crossover might involve the Assassin's Creed settings with Pokemon. Imagine exploring the ancient cities from Assassin's Creed games, but instead of just assassins, there are trainers with their Pokemon. Some Pokemon could blend into the environment like the assassins do, and they could help in combat or gathering information in a very unique way. For instance, a Flying - type Pokemon could scout areas just like the assassins' eagle vision in a sense.
One interesting crossover could be a character from Assassin's Creed using their skills in the Star Wars universe. For example, an Assassin might use their stealth abilities to infiltrate a Sith lair. They could use their hidden blade in combat against Sith warriors or droids. Another aspect could be the use of the Force in an Assassin's Creed - like way. Maybe a character discovers a new form of the Force that allows them to move like an Assassin, quickly and quietly.
The technology aspect can also be a key point. Assassin's Creed has the Animus, which allows people to relive memories. In a fanfiction, this technology could somehow end up in Gotham. Batman, being the detective and tech - savvy hero he is, could study it. He might use it to gain insights into his own past or the history of Gotham, which could be linked to the Assassin's Creed lore. And an Assassin could come to Gotham in search of the Animus, leading to their encounter with Batman.
One interesting concept could be the combination of Assassin's Creed's stealth and parkour elements with RWBY's unique combat styles. For example, a character might use Assassin's Creed - like hidden blades in RWBY battles. Another concept could be the exploration of different kingdoms in RWBY through the eyes of an Assassin's Creed - style protagonist, uncovering secrets and mysteries. Also, the idea of an Assassin's Creed character getting involved in the Grimm - fighting in RWBY's world is quite fascinating.
Well, one interesting concept could be the combination of the Assassin's Creed stealth and combat mechanics with RWBY's unique fighting styles. For example, characters might use Assassin's Creed's parkour abilities to navigate the RWBY world in really cool ways. Another concept could be the idea of the Assassins and Templars being involved in the RWBY story's overarching conflict, perhaps having different goals regarding the Dust or the Grimm. And also, the use of the Animus in the RWBY setting could lead to some really interesting plotlines, like exploring the memories of past characters from either universe.
Well, there could be a crossover where the Dark One from Once Upon a Time is interested in Elsa's powers. He might try to manipulate her into using her ice magic for his own dark purposes. Anna, on the other hand, would do everything she could to stop him, with the help of some of the heroes from Once Upon a Time like Henry. This would create a really exciting story full of magic, adventure and a battle between good and evil.
A cool crossover would be the U.A. students visiting the Hidden Leaf Village. They could participate in the Ninja Academy's training exercises. The Naruto characters could be amazed at the variety of quirks the U.A. students possess. For example, Bakugo's explosive quirk might be seen as a very unique form of ninjutsu. And the U.A. students could learn about the strict discipline and loyalty within the ninja clans.
The Force in Star Wars and the Isu (the ancient, advanced race in Assassin's Creed) could be related. Maybe the Isu were an ancient civilization in the Star Wars galaxy long ago, and they had a form of the Force. Their technology could have been based on their understanding of this power. This would blend the two mythologies as it would connect the high - tech world of Assassin's Creed with the space - opera setting of Star Wars.
