Common themes include trust - building. Since they come from different backgrounds, in fanfics, they have to learn to trust each other. Another is the exploration of their individual traumas. Snake and Raiden both have their own past traumas, and fanfics often explore how they deal with these while supporting each other. And of course, adventure. They go on various adventures together, facing new challenges and enemies.
Well, teamwork is a big theme. They are both skilled fighters, and in fanfics, they combine their abilities to take on powerful enemies. Also, redemption can be a theme. For example, if Raiden has made mistakes in the past, Snake might help him find a path to redemption. There's also the theme of mutual respect. Despite their differences, they come to respect each other's strengths in many fanfics.
One popular Snake x Raiden fanfic is 'Bond Beyond Battlefields'. It delves into their complex relationship in a post - war scenario, exploring how they rely on each other for emotional support. Another great one is 'Partners in Shadows' which focuses on their covert missions together and how their trust in each other deepens during those dangerous operations.
A common theme is the clash and then the fusion of their different worlds. Samus comes from a world of space exploration and alien battles, while Snake is from a world of military espionage and political intrigue. Their stories often involve them finding common ground.
The theme of protection also pops up a lot. The snake might protect the human from other threats in their environment, or the human might protect the snake from those who fear it. This creates a bond between them that is based on mutual trust and reliance, which is a central part of many 'human x snake fanfic' stories.
Survival is also a prevalent theme. Given the nature of the Metal Gear universe, fanfics might depict Quiet and Venom Snake relying on each other to survive in hostile environments, whether it's facing enemy forces or the harsh natural elements. They may have to work together to overcome various challenges, which in turn deepens their bond. And sometimes, there could be a theme of sacrifice, where either Quiet or Venom Snake is willing to put themselves in danger for the other's sake.
Another theme might be transformation or the blurring of boundaries between human and snake. Maybe the snake girlfriend has the ability to transform into a human - like form, and this creates interesting plot points about identity and acceptance.
Another theme might be self - discovery. As they interact, both Snake and Tabii could learn more about themselves. For example, Tabii might discover a new side of herself through her relationship with the more mysterious Snake. And Snake could find a new purpose or a different way of looking at things because of Tabii. This theme can add depth to the fanfiction and make the characters more relatable.
I'm not really into this kind of fanfic, but generally, it might involve the unique characteristics of snakes in a fictional and often very imaginative way. Maybe it could be about the relationship between snake - like creatures and other beings in a made - up world.
One common theme is the struggle for power. The OC snake shinobi often has to fight against other powerful characters in the shinobi world to gain recognition or protect something important.
Love against all odds is also a popular theme. Given their different personalities and the challenges in their world, their love story is often depicted as something that overcomes many obstacles. This can include things like differences in rank or the secrecy of Snake Eyes' identity.
Survival is also a possible theme. If the story is set in a dangerous or challenging environment, the 'quiet' and'snake' characters might have to rely on each other to survive. Their different abilities - the 'quiet' character's perhaps more subtle skills and the'snake' character's more instinctual ones - could be combined in interesting ways to overcome obstacles.
