A plot could revolve around the emotional journey of Soul and Blackstar during the mpreg. Soul might be initially scared but then becomes extremely protective. Blackstar, on the other hand, could be dealing with his own insecurities about how his body is changing and his ability to still be a strong fighter. The story could also involve a search for a way to ensure a safe delivery, perhaps involving some sort of magical or otherworldly element. They may also face discrimination from some parts of their community due to the unique nature of the pregnancy, but they overcome it through their love and determination.
One plot idea could be that Soul discovers Blackstar is pregnant and they have to deal with the shock together. They might struggle to keep it a secret from their friends at first.

Well, a possible plot is that Soul and Blackstar are in a relationship and the mpreg situation comes as a complete surprise.

Some might be supportive, while others are confused or even against it at first. And they have to face challenges like getting proper medical care in a world that may not be fully accepting of this kind of situation.
Soul is often calm and collected. During the mpreg story, his calmness could be tested as he faces the unexpected situation. He might become more nurturing, showing a side of him that was hidden before. Blackstar, who is usually brash and confident, could become more vulnerable. His self - assurance might waver as he deals with the physical and emotional changes of pregnancy.
A more complex storyline could be set in an alternate universe where they are on opposite sides of a war. They have to battle each other, but deep down they don't really want to. This internal conflict, along with their loyalty to their respective sides, would create a lot of drama. As the story progresses, they might find a way to end the war without having to completely destroy each other.
There are also fanfictions that deal with the theme of rivalry. Soul and Blackstar have a bit of a competitive streak, and some stories play up this aspect, showing how their rivalry can be both a source of tension and a driving force for their personal growth.
