One idea could be to have Naruto characters infiltrate a Metal Gear - like facility. For example, Naruto's shadow clones could be used to distract the guards while Sasuke tries to find and disable the main weapon system, similar to how Solid Snake would operate in the Metal Gear Solid games.
A third idea would be to set the fanfiction in a world where the technology of Metal Gear Solid exists in the Naruto universe. The Akatsuki could be trying to steal some new Metal Gear - style weapon for their own purposes. Konoha, in turn, sends out their best ninjas, including Naruto, to stop them. This would create a lot of interesting scenarios where the two different universes' elements interact.
Well, an interesting OC for Metal Gear Solid fanfiction could be a child soldier who was rescued by Solid Snake and then grows up to become an ally with unique combat skills. They could have a special bond with Snake and be involved in some of the major missions. You could also think about an OC who is a hacker that infiltrates the enemy's systems in a different way compared to the existing characters in the game.
One idea could be exploring the backstory of a minor character. For example, the life of a random guard in one of the bases. What led them to work there? Do they have a family? Another could be a what - if scenario, like what if Snake had made different choices during a crucial mission. It could completely change the course of the story.
Maybe a fanfiction about a new character who is a super - skilled gamer being recruited by the in - game organizations. This character could introduce new strategies and technologies based on real - world gaming knowledge, changing the dynamics of the Metal Gear Solid universe.
Some fan fictions might also focus on the relationship between Snake and the environment. Since the game is set in a jungle, there could be stories about how Snake adapts to the jungle in unique ways, or how the jungle itself seems to have a sentience of sorts and affects the events of the story.
In Naruto x Metal Gear Solid fanfiction, an interesting idea is the exchange of combat styles. The hand - to - hand combat in Metal Gear Solid, which is more grounded in reality, could be combined with Naruto's flashy and powerful ninjutsu. For instance, Raiden's high - speed sword fighting could be adapted by a Naruto character. And on the other side, Naruto characters could introduce the concept of chakra to the Metal Gear Solid world, which could completely change how combat and energy management work in that universe.
One idea could be creating an OC who is a double agent. They could be working for both Diamond Dogs and a rival organization, adding lots of intrigue and plot twists. For example, they could feed false information to the enemy while also trying to undermine Diamond Dogs from within for their own motives.
One idea could be exploring the backstory of some of the minor characters in more depth. For example, you could write about the life of a random soldier in Mother Base before Snake arrived. Another could be a 'what if' scenario, like what if Big Boss had made different decisions during a certain mission. Maybe he chose to rescue a different hostage first, and how that would have changed the overall story and relationships in the game.
Some interesting concepts in Metal Gear Solid fanfiction include the exploration of uncharted locations within the game's world. For instance, there could be hidden bases or ancient ruins that hold secrets related to the Metal Gear technology. Additionally, fanfiction often plays with the idea of alternate versions of the main characters. Picture a version of Solid Snake who was trained differently or had a different moral code. There are also concepts related to the political intrigue in the Metal Gear Solid universe being expanded upon, with new factions or power struggles emerging.
Perhaps a story where some of the Metal Gear technology finds its way into the Naruto world. Orochimaru might be interested in getting his hands on such advanced tech for his experiments. He could try to reverse - engineer it to enhance his own abilities or create new, powerful jutsu. And Konoha would have to deal with the threat of this new, unknown technology while also facing their regular enemies.
Perhaps a story where the Patriots from Metal Gear Solid are interested in the technology of Ghost in the Shell, especially the advanced cybernetic brains and how they could use it to further their control. The heroes from both sides would then have to team up to stop the Patriots' new scheme. This would involve a lot of action scenes with both the high - tech weapons from Metal Gear Solid and the cybernetic combat abilities from Ghost in the Shell.
