Fanfiction about Samus and Dark Samus can be really exciting. It allows fans to explore different relationships between them. Some might write about their epic battles in more detail, while others could create scenarios where they have to team up against a greater evil. It's a great way to expand on the Metroid universe.
Samus and Dark Samus fanfiction can also take a more emotional route. Imagine a story where Samus tries to redeem Dark Samus. She might see some potential for good in her and attempts to bring out that side. This would involve a lot of character development and could make for a very touching story.
It could be Meg. Since she's often the outcast in the show, turning her into a giantess could be an interesting twist. It would give her a new - and very literal - form of power and attention that she doesn't usually get in the show.
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.
Samus may develop by learning to see Ridley in a different light. In normal Metroid lore, Ridley is a pure villain, but in fanfiction, she could start to understand his motives or the reasons behind his actions, which could change her perception of him and thus develop her character.
Well, Reddit can be a good place too. There are some subreddits dedicated to Metroid fanfiction. You might have to do a bit of digging, but often users share links to great Samus x Dark Samus fanfictions there. Additionally, Tumblr sometimes has fanfic writers posting their works, especially in the Metroid fandom tags.
Another method is to organize fanfiction contests. Set themes that are positive and in line with the spirit of the Metroid franchise, such as Samus' heroism or her exploration of the universe. Offer prizes to the best entries to motivate more people to create positive fanfictions.
A 'giantess cuckold story' typically involves a fictional scenario where there is a giantess character in a relationship dynamic that may involve elements similar to the concept of cuckoldry in some way. However, it's often a very niche and specific type of fictional or fantastical narrative.
No. Popular stories usually have themes that are more widely understood and appealing. 'Giantess cuckold stories' are extremely niche. They involve rather complex and not - so - common relationship dynamics along with the very specific idea of a giantess. Most people are not drawn to such stories as they are far from the typical story elements that are popular in mainstream literature, movies or other forms of media.
