Well, perhaps in the fanfiction, Peter's memories as an adult are still somewhat intact in his baby form. So he tries to communicate with his loved ones in his own baby - like ways, like making specific noises when danger is near or trying to write in a very clumsy way. This could lead to some really cute and interesting interactions.
One possible plot could be that Peter Parker's transformation into a spider is a permanent one. He has to deal with not just his regular superhero duties but also the new challenges of being part - spider all the time. Maybe he has to learn new ways to communicate with other spiders to gain some special knowledge or power.
Well, one possibility could be that Peter Parker discovers he has a baby through some sort of strange situation. Maybe an old enemy left the baby at his doorstep as a way to get revenge, making his life even more complicated as he tries to balance being Spider - Man and taking care of a new - born.
Well, perhaps in the fanfiction, Peter and Gwen find an abandoned baby with some sort of special powers. They decide to take the baby in and raise it as their own. As they do so, they have to face various challenges. Enemies might be after the baby because of its powers. Peter uses his skills as Spider - Man to keep the baby safe, while Gwen provides the emotional support and care. They grow together as a family in the face of these difficulties.
One possible plot twist could be that Peter's identity as Spider - Man is revealed to the public much earlier than in the original story. Since Tony Stark is his adopted father, he has to use all his resources and influence to protect Peter from the various threats that come with this exposure. This could lead to a lot of interesting scenarios, like Stark having to face off against some of his own business rivals who might want to use Peter's powers for their own gain.
In some fanfictions, Peter's death might be a result of a long - term consequence of his superhero activities. For example, the constant use of his powers could have weakened his body over time, leading to a tragic end. It could also be that a new and unexpected enemy emerges, one that he underestimates and this ultimately costs him his life. The death then serves as a shock factor to drive the story forward, perhaps leading other characters to avenge him.
One possible plot twist could be that the pregnancy is part of a villain's scheme. Maybe an enemy has found a way to manipulate their DNA to force the pregnancy, and Peter and Hippolyta have to find a way to reverse it while also dealing with the moral implications. Another twist could be that the pregnancy is a result of some sort of time - travel or alternate - reality mix - up. For example, they might be from different universes where such a union and pregnancy would not normally occur, but due to some cosmic event, they are now in this situation. A third plot twist could be that the pregnancy reveals a hidden power within their unborn child. This power could be something that both heroes and villains are after, putting the couple in a very dangerous position as they try to protect their future family.
One possible plot twist could be that Mystic has a secret identity or past that threatens their marriage. For example, she might be related to one of Peter Parker's enemies without knowing it. Another could be that a powerful villain tries to use their marriage as a way to get to Spider - Man. Maybe they put a spell on Mystic to make her turn against Peter.
One possible plot twist could be that Amora's Asgardian heritage causes problems. Maybe some Asgardian law or custom forbids her from marrying a mortal like Peter Parker. For example, the Asgardian council could oppose the union and send someone to stop it, creating a conflict for the couple to overcome.
One creative plot twist could be that Peter, after turning into Carnage, retains his moral compass. So instead of going on a rampage, he uses the Carnage symbiote's powers for good. For example, he might be able to heal people with the symbiote's tendrils in a new and unexpected way.
His relationship with MJ would become very different. Instead of a romantic partner, she might become more of a protective caretaker. She would have to deal with a baby - like Peter, which could be both challenging and endearing.
