A plot could revolve around Tony making a sacrifice play to protect Peter, but Peter using his spider - sense and quick thinking to turn the tables and save both of them and also play a crucial role in halting Thanos' plan. This would show their strong bond and how they complement each other.
Maybe a fanfiction where Peter gets separated from Tony during the chaos of the war and has to find his way back to him while facing various challenges from Thanos' minions. He could discover new abilities within himself during this journey.
One idea could be Peter trying to convince Tony to use a more risky but potentially game - changing strategy during the battle in Infinity War. For example, he might suggest using his new - found powers in a way that Tony is initially hesitant about.
One plot idea could be that Tony discovers Peter has a hidden talent for advanced robotics engineering that he's been too shy to show. So, Tony takes Peter under his wing to develop this talent further. Another could be that Peter gets into some kind of trouble at school related to his superhero identity, and Tony has to step in as a father figure to help him out. Maybe Peter accidentally reveals his powers in front of some untrustworthy people at school, and Tony has to deal with the potential exposure.
One idea could be to have the cartoon versions of the heroes and villains swap powers. For example, Iron Man could end up with Thor's lightning powers and Loki could have access to Captain America's super - soldier strength. This would lead to really unique battles and character development as they struggle to control new abilities.
One idea could be exploring the family dynamics within the Avengers during the Infinity War. For example, how do the different characters who have a sort of family bond, like Tony Stark and Peter Parker, deal with the chaos of the war? Another could be a fanfiction where a superfamily from a different dimension arrives to help in the Infinity War and how they interact with the existing heroes.
Peter's character can be developed by having him face some really tough moral dilemmas. For example, in the Infinity War chaos, he might have to choose between saving a group of civilians or going after an important Infinity Stone. This would force him to think like a true Avenger and not just a friendly neighborhood Spider - Man.
In fanfiction, their relationship could be deepened by having them share personal stories from their past. Maybe while waiting for an attack, Tony tells Peter about his early days as Iron Man and the mistakes he made, and Peter in turn shares his feelings about losing Uncle Ben. This would bring them closer.
Well, the intense and dramatic moments between Peter and Tony in Infinity War likely inspired the creation of sad cartoons and memes. People express their feelings through this form of art and creativity.
The fanfic could explore a scenario where Steve and Tony are both injured during Infinity War. They are in a hiding place, waiting for help or for a chance to strike back. In that moment of vulnerability, they realize how much they mean to each other. The kiss is a sign of their mutual support and love. It becomes a turning point for them, giving them the motivation to heal quickly and come up with a new strategy to defeat Thanos.
One idea could be a pre - Infinity War story where the Guardians try to steal an Infinity Stone from a powerful and unexpected enemy. Maybe a new race that has been secretly collecting powerful artifacts.
One idea could be the remaining Avengers finding a way to reverse the Snap in a completely unexpected way, like traveling to a different dimension where Thanos never got the Stones. Another could be the rise of new heroes among the survivors, who have unique powers that can help in the fight against Thanos' legacy. And perhaps some of the snapped heroes are actually alive in a sort of pocket universe and the Avengers have to figure out how to bring them back from there.
Perhaps in the fanfiction, the Infinity War concept causes some members of the Justice League to turn on each other. Maybe the power of the Infinity Stones - like objects corrupts some of them, like if Flash gets too tempted by the power of speed - enhancing stones and starts causing chaos instead of helping. Then the rest of the team has to figure out how to stop their former ally and also the external threats.
