Well, it could start with a strange encounter between Peter and Hera. Then, as the pregnancy is discovered, Peter would be filled with a mix of emotions - excitement, fear, and a sense of responsibility. He'd have to balance his superhero duties with taking care of Hera. Maybe he'd swing around the city less often to be by her side.
The fanfiction could also explore how their different worlds would react. Peter's world of superheroes and villains would be in shock, while Hera's world of gods and goddesses might see it as a major event. There could be a plot where some villains try to take advantage of the situation, thinking that a pregnant Hera and a distracted Peter would be easy targets, but they'd be wrong as Peter and Hera would team up and prove their strength.
One possible scenario could be that in this fanfiction, Hera, perhaps in a unique crossover universe, has a relationship with Peter Parker. The pregnancy might bring out a more protective side of Peter. He could start to use his powers and intelligence in new ways to ensure the safety of Hera and their unborn child, like creating special gadgets for their home security.
It could unfold with a lot of drama. Betty might face health issues during the pregnancy that Peter has to deal with. He could use his scientific knowledge to help, being the smart guy he is.
Their story could start with an unexpected encounter that leads to an attraction. Maybe they meet during a battle where they initially see each other as enemies but then something changes. After getting married, they'd have to deal with keeping their relationship a secret from the public and some of their superhero friends who might not approve. They could go on adventures together, with Peter trying to keep Titania in line and Titania pushing Peter to be more assertive in his superhero identity.
Perhaps the fanfic would unfold with Mantas feeling Peter's feelings during a big battle. Peter is terrified but also determined, and Mantas experiences these emotions firsthand. This could prompt Mantas to try and help in some way, like gathering information for Peter or providing a safe place for him to rest. The story could then develop into Mantas becoming an important part of Peter's support system, and they grow closer as Mantas continues to be attuned to Peter's feelings.
Well, one way the story could unfold is that Bucky, in his complex past, somehow had a child without knowing it and that child turns out to be Peter Parker. Peter might inherit some of Bucky's combat skills in a more natural way, like through genetics. Maybe Peter discovers the truth when he starts having strange memories or abilities that don't seem to come from his usual Spider - Man origin. This could lead to a whole new arc in his superhero journey, where he has to reconcile his identity as Spider - Man with his newfound family connection to Bucky.
It would change in many ways. They'd probably have more arguments as they deal with different views on raising the child. Felicia, with her more independent nature, might clash with Peter's over - protective instincts. But at the same time, they'd also have more tender moments, realizing they are creating a family together.
A Peter Parker and Mary Jane pregnant fanfiction could explore their relationship by highlighting their insecurities. Mary Jane might worry that Peter will be too distracted by his superhero duties and not be there for her and the baby. Peter, on the other hand, might be afraid that he won't be a good father. But as they go through the pregnancy together, they learn to trust each other more. They share tender moments, like feeling the baby kick together, which brings them closer and shows the strength of their relationship.
His life would change in many ways. First, he would need to be more present at home. No more staying out all night as Spider - Man. He would have to ensure Black Cat has proper medical care, which might mean finding a doctor who can be discreet about their identities. Also, he'd need to start thinking about finances. Babies are expensive, and he can't rely on his meager reporter salary alone. He might have to take on more side jobs or find ways to earn more money legally. Emotionally, he'd be a bundle of nerves, constantly worried about the safety of Black Cat and the unborn child.
Their relationship would become more serious and committed. Before the pregnancy, they might have just been exploring their feelings, but now they have a future together to think about. They would rely on each other more, with Peter being more protective of Sue and Sue depending on Peter for emotional support during her pregnancy.
Peter would probably be shocked at first. He's used to dealing with super - villains and saving the city, not impending fatherhood. But then he would likely step up and be very protective. He'd make sure Jean had the best medical care and start thinking about how to keep their home safe from any threats.
