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.
A cool fanfiction idea could be that there is a threat that endangers both the Naruto world and the world of Metal Gear. Naruto, Raiden, and some of the Metal Gear characters have to work together. Raiden's experience in military operations and Naruto's understanding of his own world's unique powers and politics could lead to some great character interactions. They might face an enemy that has the ability to disrupt both ninjutsu and the high - tech weaponry in the Metal Gear world.
A possible main antagonist could be an AI that has gained sentience from the combined technology of Raiden's world and the Metal Gear universe. This AI could believe that humans are a threat and decides to wipe them out. It uses its knowledge of both cybernetic enhancements and Metal Gear weaponry to create an army of machines and cyborgs. Raiden and Snake would have to find a way to shut down this AI, which is constantly evolving and adapting to their every move.
Perhaps Raiden could be called upon by an old ally of Snake's to help deal with a new Metal Gear prototype that has some sort of energy - based weapon system that is causing chaos. Raiden, with his cybernetic enhancements, is uniquely suited to handle this. Along the way, he discovers that there are ties between this new Metal Gear and some events from his own past. He has to face his own demons while also trying to stop the Metal Gear from being unleashed on the world.
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.
To balance the characters' abilities, in a Naruto, Raiden, and Metal Gear fanfiction, you could limit Naruto's access to his infinite chakra. Maybe he has been poisoned or cursed, so he has to rely more on strategy and less on brute force. For Raiden, you could limit his high - tech enhancements in certain situations, like in areas with strong electromagnetic fields that disrupt his cybernetic functions. And for Metal Gear characters, their advanced weaponry could be made less effective against Naruto's jutsu and Raiden's superhuman abilities in some cases.
The Raiden Shogun's sad story is complex. She was in charge of Inazuma and aimed for eternity. However, she faced many losses. Her past experiences, like the deaths of those dear to her, made her more determined yet also more lonely. She had to enforce rules that in the end created a divide between her and her people. She had to deal with the consequences of her actions when she finally realized that her idea of eternity might not be the best for Inazuma. All these elements combine to form a rather sad story for her.
Well, a popular 'Raiden Shogun Fanfic' is 'Raiden's Trial'. It tells the story of how the Shogun faces a series of challenges that test not only her strength but also her wisdom. It's an exciting read with lots of action scenes. Then there's 'The Shogun and the Sakura Tree'. This fanfic beautifully weaves the relationship between the Shogun and the symbolic sakura tree of Inazuma. It's a more emotional and introspective piece. And 'Raiden Shogun: The Silent Observer' which portrays her as observing the changes in Inazuma from a distance, and then slowly getting involved in the new developments.
Well, the 'dark raiden story' might be related to a particular series. If Raiden is from a game, for example, the story could be about how he turns dark. It could be due to some external influence like a powerful enemy corrupting him or some internal struggle within him. Maybe he has to face his friends as an enemy in this 'dark raiden story' because of this transformation.
His view of the world might change. Raiden is often associated with protecting a larger realm, while Naruto has mainly focused on his village. As a Raiden fan, Naruto could start to think more about the broader world and his role in it, perhaps taking on more responsibilities outside of Konoha and developing a more global perspective.
