For Raiden crossover fanfiction, a cool concept could be a crossover with the Final Fantasy series. Raiden could be a summonable character in a Final Fantasy game, with his lightning attacks being a powerful addition to the party's arsenal. Another idea is a crossover with the Transformers. Raiden could interact with the Autobots and Decepticons, maybe even using his powers to help in their battles on Earth. A third possibility is a crossover with the Naruto universe. Raiden could teach Naruto about controlling and using chakra in a different way, given his own control over electricity which is somewhat similar to chakra in the Naruto world.
One idea could be a Raiden crossover with the Mortal Kombat universe. Raiden could team up with other iconic characters like Scorpion or Sub - Zero to fight a common enemy that threatens both their worlds. Another idea is a crossover with a cyberpunk - themed world. Raiden, with his electric powers, could fit well in a high - tech, dystopian setting, perhaps fighting against corrupt corporations or rogue AIs. And a third idea could be a crossover with a fantasy world, where Raiden's god - like powers make him a key figure in a battle between good and evil magic forces.
One idea could be Raiden being transported to an alternate universe where the rules of Mortal Kombat are completely different. He has to quickly adapt and find a way back home while facing new and strange opponents. Another could be Raiden teaming up with a Mortal Kombat character he's never interacted with before, like Johnny Cage, to defeat a common enemy that threatens both their worlds. Maybe this enemy has the power to disrupt the balance of the realms, which is Raiden's main concern.
There's also 'Raiden in a Parallel World' where Raiden gets transported to a different dimension filled with unique challenges and allies. The story is well - written, with great character development for Raiden as he adapts to this new world. It's a must - read for fans of crossover fanfiction.
One possible plot could be that Naruto, being from his ninja world, somehow gets transported to Raiden's universe. He could be in awe of Raiden's power which is so different from chakra. Naruto might try to learn from Raiden about his abilities and fighting style. And Raiden could be intrigued by Naruto's never - give - up attitude and his ability to make friends so easily. They could team up against a common enemy that threatens both their worlds.
One popular character to include is Batman from DC Comics. The contrast between Batman's detective skills and gadgets and Raiden's superhuman powers would be fascinating. Another is Goku from Dragon Ball. Goku's love for fighting and his ability to reach new levels of power could lead to some epic battles with Raiden. And of course, Samus Aran from Metroid. Samus' armored suit and her exploration of alien worlds could be combined with Raiden's adventures in a unique crossover story.
Another theme is the clash of cultures. Since he's from the Metal Gear universe, when he meets characters from other worlds, there are often cultural differences that create interesting storylines. Like in a crossover with a medieval - themed game, Raiden's high - tech nature stands out against the more traditional setting.
Shang Tsung would be a great villain. He's always after power and could see Raiden as a threat or a means to gain more power. His sorcery could pose a serious challenge to Raiden. Another one could be Shao Kahn. He wants to conquer all realms, and Raiden's realm would be no exception. His brute force and army could make for an epic showdown against Raiden.
One idea could be a Jessie crossover with a superhero universe. Jessie could use her skills and charm to team up with superheroes, perhaps helping them understand the value of friendship like she does with her friends in her own show. Another could be a crossover with a fairy - tale world where she brings her modern - day smarts to solve problems in a magical realm.
One idea could be a crossover between Usopp and the world of Harry Potter. Usopp could be a wizard who uses his creativity and skills to create unique magical items and tricks, much like his inventions in his own world. Another could be a crossover with the DC universe, where Usopp teams up with the Green Arrow. They both have skills with ranged weapons and could learn from each other. A third idea is a crossover with the Final Fantasy series. Usopp could find himself in a world full of magic and strange creatures, using his wits to survive and help the characters there.
For a Matilda crossover fanfiction, consider a crossover with The Secret Garden. Matilda could help bring the garden back to life with her unique abilities. Or, a crossover with Charlie and the Chocolate Factory. She could use her smarts to solve some of the strange mysteries in Willy Wonka's factory. Also, a crossover with Peter Pan would be interesting. Matilda could befriend Peter and the Lost Boys and use her powers to fight Captain Hook.
One idea could be an Ansem crossover with a popular fairy - tale world. For example, crossing Ansem with the world of Alice in Wonderland. Ansem's dark and mysterious nature could contrast well with the whimsical and often illogical world of Wonderland. He could be on a quest for some dark power hidden within the Wonderland, interacting with characters like the Cheshire Cat or the Queen of Hearts in his own devious way.
