One great fanfiction in this vein could be 'The Kryptonian Heir'. It beautifully explores how Superman deals with the impending fatherhood while still protecting Metropolis. It delves into his relationship with Lois during her pregnancy, showing their love and the challenges they face together.
Their relationship can be shown as even more loving and protective. Superman would be constantly worried about Lois and the baby, and Lois would appreciate his care while also being her strong - willed self. For instance, he might fly her to her doctor's appointments super - fast to avoid traffic.
One popular plot twist could be that Lois discovers she's pregnant with a super - powered baby. This might bring up concerns about how to raise a child with such abilities in a world that might not understand. Another could be that Superman has to deal with an enemy who targets Lois because of her pregnancy, seeing it as a way to get to him.
Definitely Lex Luthor. His jealousy and hatred for Superman could be amplified by Lois's pregnancy. He might see it as a way to create a new super - being under his control or try to use the baby as a weapon against Superman. Another interesting character could be Martha Kent. Her wisdom and experience could be a great support for Lois during the pregnancy.
One idea could be exploring how they balance their superhero and normal lives while preparing for the baby. For example, Superman might have to deal with villains while also making sure Lois is safe during her pregnancy. Another could be a story where Lois discovers some new super - power related to her pregnancy, like being able to sense danger to the unborn child.
One common theme is the relationship between Superman and Lois. Writers often explore how their love story unfolds and how they support each other. Another theme is Superman's identity and how Lois helps him keep it a secret or deal with the consequences if it's revealed.
One idea could be that Superman has to balance his superhero duties while also being extra protective of Lois during her pregnancy. He might use his powers in new and creative ways to ensure her safety and comfort. For example, he could create a special force field around her when she's out in public.
Well, it's hard to say who the 'best' is as it depends on personal taste. But some popular authors include those who really capture the essence of the characters. For example, some authors who are good at writing the emotional side of Superman and Lois Lane's relationship. They can make you feel the love, the tension, and the drama between them.
