One common theme might be protection. Since it involves a baby Samus, Snake could be portrayed as her protector. Another could be discovery, as the baby Samus discovers the world around her with Snake's help.
I think growth could be a theme. As the baby Samus grows, Snake could play a role in her development. Also, friendship could be a theme. Despite their differences, they could form a unique bond in the fanfiction. There could also be a theme of facing challenges together, like fighting against common enemies or overcoming difficult situations.
A common theme is the clash of different worlds. Since Snake comes from a more military - espionage - like world and Samus is from a sci - fi, alien - hunting world, their stories often explore how these two different universes collide. For example, in many fanfictions, they have to adapt to each other's technology.
Well, a frequent theme is the exploration of their unique skills. Solid Snake is known for his stealth and combat skills, and Samus has her advanced weaponry and agility. Fanfictions might show them learning from each other's abilities. Also, there can be a theme of mutual respect. Given their individual achievements in their respective universes, stories may depict how they come to respect one another's capabilities and experiences. And sometimes, there's a bit of a culture shock aspect as they come from very different game backgrounds.
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.
One common theme is exploration. Samus is often depicted exploring new planets or areas. For example, in many fanfictions, she lands on uncharted planets filled with strange creatures and ancient ruins. Another theme is self - discovery. As she faces new challenges, she learns more about herself and her limits. Also, the theme of heroism is prevalent. Samus is a hero, and fanfictions often show her saving the day in different situations.
I'm not sure about specific snake and samus baby fanfiction. But you can try looking on some popular fanfiction websites like Archive of Our Own or FanFiction.net. There might be some unique stories there.
One common theme is the battle between light and dark. Samus represents the light side, being a bounty hunter who fights for good in the Metroid universe, while Dark Samus is, as the name suggests, the dark counterpart. Their relationship in fanfiction often explores this contrast.
One common theme is the crossover of their worlds. Writers often bring Samus into the world of Zelda or vice versa to create new and exciting settings. For example, Samus might have to navigate the dungeons of Hyrule using her power suit.
Another theme is the power of teamwork. Since they are both strong and capable heroes in their own right, fanfictions like to show how they can combine their strengths. They might use Link's swordsmanship and Samus's marksmanship to take on a super - powerful foe that neither could defeat alone. It's about the synergy between their abilities.
One common theme is self - discovery. Samus often has to learn more about herself and her powers in these fanfictions. Another is the exploration of new planets and dealing with unknown species, which ties in with the Metroid universe's vastness.
One common theme is adventure. Since Samus is known for her adventures in different planets and galaxies, when she meets Si, they often embark on some sort of journey together. Another theme could be self - discovery. Si might learn something new about themselves through their interactions with Samus, and vice versa. And of course, there's the theme of friendship or alliance, as they usually have to work together against foes.
