I'm not entirely sure, but I don't recall Peter Green being in 'Pulp Fiction'. There are a lot of actors in that movie, but I don't think he's one of them.
When Peter stops holding back fanfiction, it might also imply that he has overcome some internal barriers. It could be that he has grown as a writer and is now ready to expose his work to a wider audience. He may have found his own unique style and voice in fanfiction writing and is confident that his work will be well - received. This could lead to a flood of new and exciting fanfiction from him, exploring various aspects of the source material that he was previously suppressing.
It could be a new villain who manages to make Peter question his role as Spiderman. This villain might use mind - games or expose Peter's identity in a way that makes him want to give it all up.
Maybe Peter gets tired of the double life. He realizes that being Spiderman has cost him too much, like his normal relationships or his own mental health. So he decides to give up the mantle.
Another reason might be related to some sort of experiment gone wrong. Peter is often involved in scientific research. If there was an accident in his lab, perhaps with a new type of spider - related serum or some other experimental technology, it could have unforeseen consequences on his heart and lead to it stopping.
In some fanfictions, Peter could have a sort of out - of - body experience. He might meet some important figures from his past or gain some new insights while his heart is stopped. This could then influence the way he approaches life and heroism once he is revived. And when he is revived, he might come back with new powers or a stronger sense of purpose.
Since Peter Green is not an actor in 'Pulp Fiction', there is no role for him to play in it. The movie has its own set of characters and actors who bring the story to life, and Peter Green is not part of that.
One main theme is power and responsibility. Both Peter Parker as Spider - Man and the Green Lantern have great power, and the fanfictions often explore how they use it responsibly. Another theme could be identity. Peter has to figure out how being a Green Lantern affects his identity as Spider - Man.
