To write a great Master Chief and Arbiter lemon fanfic, start with a strong foundation of the Halo universe. Familiarize yourself with the lore, the cultures of both humans and the Covenant. When it comes to the characters, show their growth. For Master Chief, you could explore how he opens up to Arbiter, and vice versa. For the 'lemon' aspect, make it an organic part of the story. For example, it could be a result of a deep emotional bond that forms during a difficult mission they undertake together. Also, vary your writing style. Use short, impactful sentences during action scenes and more descriptive, flowing sentences during emotional moments.
A lot of fanfictions also focus on cultural exchange. The Master Chief is from a human military background, while the Arbiter is from the Covenant. Their interactions can lead to interesting cultural exchanges. For example, they might learn about each other's beliefs, values, or military strategies. Some fanfictions may also delve into a more complex relationship where they have to overcome initial distrust or misunderstandings due to their species' past conflicts.
Well, one possible plot could be a story of alliance. Maybe they team up to face a common enemy that threatens both of their species. They start off distrustful of each other but as they fight side by side, they begin to respect and understand one another.
One interesting storyline could be them teaming up against a new, powerful alien threat that neither the UNSC nor the Covenant remnants can face alone. They start off distrustful but gradually learn to respect each other's skills and cultures.
A Master Chief and Arbiter lemon fanfic is unique because it brings together two very distinct characters. Master Chief is known for his stoicism and unwavering dedication to humanity. Arbiter, on the other hand, has gone through a journey of redemption. When you put them together in a fanfic, especially with a 'lemon' element, it could be a way to explore their characters in a more intimate and emotional way. It might show a side of them that we don't see in the main Halo games, like how they deal with personal feelings towards each other, be it friendship, respect or something more, against the backdrop of the grand Halo universe.
They would likely have a cautious start. Master Chief is used to his own ways and the Female Arbiter has her own set of beliefs. But as they interact more, they might exchange combat techniques. For example, Master Chief could show her some of his advanced weapon handling skills, and she could teach him about her people's unique forms of combat.
One possible storyline could be them teaming up against a new, powerful alien threat that neither the UNSC nor the Covenant can face alone. They have to put aside their differences and combine their unique skills and knowledge. Master Chief's combat expertise and the Female Arbiter's understanding of Covenant politics and technology would make for an exciting partnership.
Their relationship can be developed through shared battles. For example, when facing a common enemy, they start to rely on each other's unique abilities. Master Chief's superhuman combat skills and Arbiter's leadership within the Covenant structure can complement each other.
A plot could revolve around a mystery that involves both of their species. The Female Master Chief and the Arbiter start investigating it separately, but their paths cross. As they dig deeper, they realize that their fates are intertwined, and they must rely on each other not only to solve the mystery but also to survive the dangerous forces that are trying to stop them.
