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 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.
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.
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.
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 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.
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.
One idea could be an OC who is a master of stealth technology, perhaps even surpassing Snake in some ways. They could be on a mission to uncover a new type of Metal Gear that has been secretly developed by a rogue faction within the military - industrial complex. Another plot could involve an OC who has a unique connection to the AI systems in the Metal Gear universe, and they have to prevent the AI from going rogue and causing global chaos.
One interesting story could be about unique character interactions that deviate from the original game's plot in a creative way. For example, exploring how characters might form unexpected alliances or rivalries.
A cool concept in Metal Gear Solid crossover fanfiction is a crossover with superhero universes. Picture Solid Snake in the Marvel or DC universe. He could be a unique anti - hero among all the super - powered beings. He might use his stealth and combat skills to take on villains in a different way. Also, a crossover with the Legend of Zelda series could be fascinating. Snake could find himself in the magical world of Hyrule, trying to figure out how to use the Master Sword or deal with the various monsters there. It would be a strange but interesting blend of two very different fictional worlds.
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.
