Since I haven't read this particular 'neo x penny fanfiction', it's hard to say precisely. However, in general, fanfiction often takes existing characters and gives them new story arcs. So for Neo and Penny, it could involve them having superpowers they didn't have before, or being part of a secret society. It might also explore their backstories more deeply, like how they grew up or what made them the characters they are, and then build a new plot around that.
In fanfiction, their relationship could be developed by exploring their similarities. They are both unique entities within the Matrix. Neo is the One, and Smith is the virus - like Agent. By delving into how they both are outliers in the system, they could start to understand each other on a deeper level. This could lead to a complex relationship that is part rivalry, part reluctant alliance.
Their relationship could develop through shared experiences. For instance, if they both get trapped in a malfunctioning part of the Matrix. They have to rely on each other's skills. Neo's ability to manipulate the Matrix and Agent Smith's knowledge of its inner workings would be crucial. This would lead to a grudging respect between them.
One common theme is friendship. Despite their differences, Neo and Ruby often form a bond in these fanfics. Another theme is self - discovery. As they interact, both characters learn more about themselves.
One common theme is redemption. For example, Cinder might be on a path to redeem herself and Neo could play a part in that journey. Another theme is friendship or an unlikely alliance. They are from different backgrounds and having them form a bond is an interesting exploration.
One common theme is power. Neo and Cinder both possess unique powers, and in fanfiction, their powers are often explored in relation to each other. For example, how they can use their powers to protect or support one another.
It could be an evil ninja who has somehow gained access to the technology from Neo's world and wants to use it to take over the Naruto world. He might be able to create clones using digital technology, making him a very difficult enemy to defeat.
One common theme is friendship. Despite their differences, Neo and Ruby might form an unexpected bond in these fanfics. Another theme could be adventure, where they go on quests together.
The writing style also matters. A vivid writing style can bring the world of Remnant to life. Describing the settings, like the seedy underworld bars they might frequent or the dark alleys they use to escape pursuers. And of course, the way the author writes their interactions, whether it's a shared glance or a coordinated attack, should be engaging and believable.
The theme of redemption can also be found in some 'rwby neo x roman fanfic'. Some stories might explore the idea of them trying to break away from their criminal pasts and find a new path, with their relationship being a key factor in this journey. Their connection can be what gives them the strength to seek redemption.
