A common theme is the struggle for control. The symbiote has its own will, and Peter often has to fight to keep it in check. For example, in many fanfics, he battles with the symbiote's urge to be more violent.
Peter could get a dog. A loyal dog would be a great companion for him, following him around during his daily life and even being a sort of sidekick. It could sense danger and bark to alert Peter when something was wrong.
One great Symbiote Peter Parker fanfic is 'Venomous Intent'. It explores a darker side of Peter with the symbiote, full of intense action scenes and moral dilemmas.
To develop her character, first, focus on her initial reaction to the symbiote. Is she excited, scared, or both? Then, show how she adapts to the new powers. For example, if the symbiote gives her enhanced strength, does she accidentally break things at first? Also, explore her relationships. How do her friends and family react to her new form? And how does she handle that? Another aspect is her moral compass. Does the symbiote's influence ever make her question her values?
It could be a vengeful criminal that Spider - Man has put away in the past. This criminal has spent years in prison plotting his revenge and finally gets the chance when Peter is vulnerable. Maybe he manages to ambush Peter in an alleyway while he's on his way home from school or work.
One idea could be that Peter Parker gets a prosthetic after a particularly dangerous battle with a villain. Maybe his leg is severely injured and he has to adapt to the new prosthetic while still maintaining his superhero duties. He could struggle at first with the balance and movement, but with his determination, he eventually masters it and even modifies the prosthetic to have some special features like enhanced jumping ability.
Well, a possible plot for female Peter Parker with a symbiote could involve her using the symbiote to explore new parts of the city that she couldn't reach before. The symbiote might allow her to climb higher buildings or swing faster. Also, she could have an internal conflict where the symbiote tries to influence her decisions in a more self - serving way. She has to constantly fight against this influence while still using the symbiote's power. Additionally, she might encounter other symbiote - related characters who either help or hinder her journey.
His personality might become more in touch with his emotions. As a girl, Peter could be more empathetic and sensitive. He might also be more cautious in some situations, as society often treats girls differently. For example, he might not be as quick to jump into a fight without thinking about the consequences more carefully.
The 'Peter Parker Gets Stitches' fanfiction might be centered around the idea of vulnerability. Peter is often seen as a strong superhero, but getting stitches shows his human side. It could be about how he copes with this moment of weakness. There could be a lot of internal monologue as he sits in the hospital or wherever he gets the stitches, thinking about his responsibilities and how this injury might impact his future as Spider - Man.
Peter Parker is the main character for sure. In addition to Aunt May and MJ, there could be other characters from the Spider - Man universe. For example, Doctor Strange could make an appearance if the injury has some sort of magical or other - worldly aspect to it. Or perhaps Iron Man's influence could be felt if the story is set in a universe where they have interacted. And let's not forget the Daily Bugle crew, like J. Jonah Jameson, who might be looking for a story about Spider - Man's injury.
