Adrian Toomes is a significant antagonist. He's a brilliant inventor who turns to crime to get what he wants. His Vulture suit gives him enhanced abilities and makes him a threat to the heroes.
Another theme could be secrecy and identity. Peter has to keep his identity as Spider - Man a secret, and Toomes also has his own secrets. Fanfictions might play with how they deal with each other's secrets and how it affects their relationship. For example, there could be a plot where they gradually discover each other's true selves and how that changes their bond.
Fanfiction.net could also be a place to look. However, the tagging system might not be as precise as AO3. But still, it has a vast amount of fanfiction, so it's worth a try. Just search for the specific pairing, and you may come across some interesting stories.
I'm not sure specifically as there could be many different 'toomes shoots peter' fanfictions. It might be about a conflict situation where Toomes shoots at Peter. It could be a creative take on a battle or a tense moment between these two characters in the fan - created story.
You could try searching on popular fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. Just type in the keywords 'toomes shoots peter' in their search bars and see what comes up.
I also like 'Adrian's New Path' which shows a different side of Adrian. In this fanfiction, he tries to break away from his violent tendencies and build a more normal life. It's interesting to see how the author portrays his journey towards redemption and self - discovery.
I'm not entirely sure specifically as 'adrian cloustrophibic fanfiction' isn't a widely known common term. It could potentially be fanfiction related to a character named Adrian who has some sort of claustrophobic - related experiences or themes in the story.
One common theme is self - discovery. Adrian often has to learn about his own abilities or his past in many fanfictions. For example, in stories where he has a special power, he has to figure out how to use it and what it means for him.
