Yes, in some Iron Man 2 fanfictions, Peter Parker can be the kid. Fanfiction writers often like to create crossovers and connections between different characters from the Marvel universe. It adds an interesting twist to the story.
I'm not sure specifically who the 'umbrella man' in the Peter Max story is without more context. It could be a unique character created within the context of one of Peter Max's works, perhaps someone with a symbolic role related to his art, like an individual representing a certain era or idea that Max was trying to convey through his art and the associated story.
One great fanfiction idea could be that Gwen discovers Peter's secret identity in a really unexpected way. Maybe she stumbles upon his Spider - Man suit while looking for something in his room. This would create a lot of drama and tension between them as she has to decide what to do with this knowledge.
I don't have a detailed knowledge of it. But it could potentially be a story full of surprises and twists, with Peter Max using the umbrella in unexpected ways.
Doctor Octopus is also a likely candidate. His mechanical arms and high intelligence could give him an edge. He could manipulate a situation where Peter is caught off - guard and unable to defend himself, resulting in his death.
One possible aspect of 'Spider Man Peter, Child of the Universe' fanfiction could be exploring Peter's new powers. Since he's considered a 'child of the universe', he might have abilities beyond the typical Spider - Man powers. Maybe he can communicate with cosmic entities or have a deeper understanding of the fabric of the universe.
One possible fanfiction idea could be that Peter gets sick right before a big battle. He has a high fever but still tries to put on his suit. His spidey - sense is all messed up because of his illness, making it harder for him to dodge attacks. His friends, like Ned and MJ, find out and try to convince him to stay home and rest. But Peter, being the selfless hero he is, goes out anyway and has to rely more on his wits than his usual super - reflexes to win the fight.
One great fanfiction could be where Gwen and Peter team up to solve a mystery in the city that the regular Spider - Man villains are not involved in. It could show their unique dynamic and how they complement each other's skills.
One great fanfiction idea could be Peter and MJ going on a double - date with Ned and his girlfriend in the Spider - Man PS4 universe. They could have an adventure while trying to find a new, cool place to eat in New York City.
