The Arbiter makes his appearance at different points depending on the specific Halo novel. It varies, so it's hard to give a precise answer without knowing which specific novel you're referring to.
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.
Well, 'A New Dawn for Allies' is another one. It's set in a post - war scenario where the Arbiter and the Chief are trying to rebuild relations between their species. It shows their struggles, not just in terms of the physical rebuilding but also in the cultural understanding and acceptance of each other.
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.
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.
