Well, one idea is that Spider - Man's death could be a catalyst for a new hero to emerge. Maybe a young kid who was inspired by him decides to take up the mantle in his honor. Another idea is that his death causes a rift among the Avengers. Some blame themselves for not being able to protect him, while others want revenge on Thanos immediately.
One possible fanfic could be where Spider - Man's death is more of a sacrifice to save others. Maybe he uses his powers to hold off Thanos' minions long enough for the remaining Avengers to escape. His last moments could be filled with thoughts of his friends and Aunt May, and his determination to do what's right.
One idea could be that Spider - Man discovers a hidden power within himself during the Infinity War. Maybe he has a unique connection to the Infinity Stones that no one else realizes. This power could help him turn the tide in some crucial battles.
One idea could be that Spider - Man discovers a hidden power within himself during Infinity War that allows him to turn the tide of the battle. Maybe he can communicate with the Infinity Stones on a deeper level, using his spider - sense to detect their weaknesses and strengths.
One idea could be exploring the backstories of the minor characters in more depth. For example, showing how the Wakandan warriors trained and what their lives were like before the big battle. Another could be a what - if scenario where Thanos actually had a change of heart at the last minute. Maybe he saw the beauty in the universe he was about to destroy and decided to stop.
Yes, Spider-Man was in the Infinity War comics. He played an important role in the battle against the cosmic threats.
His relationships could also play a big role in his development. Maybe he forms a really close bond with one of the other Avengers during the war. This friendship could teach him new things, like how to better control his powers or how to be more of a team player. And if he loses this friend in the war, it could be a huge turning point for his character, making him more determined and perhaps a bit more jaded.
There are fanfictions where Spider - Man's identity is revealed and the villains target his loved ones. In his attempt to protect them, he ends up in a battle he can't win. His death shakes the Avengers to their core, making them reevaluate their methods of protecting heroes' families and also their own safety protocols.
Perhaps Spider - Man starts to train harder in order to be better prepared for future threats. He could seek out new mentors, like Doctor Strange if he's still around. He might also get involved in some sort of community rebuilding effort, using his powers to help the common people who are now in a state of chaos and fear.
One idea could be to have the Avengers travel back in time to prevent Thanos from ever getting the Infinity Stones in the first place. They could team up with their past selves and use their knowledge of the future to outwit him. For example, they could stop Ronan from getting the Power Stone in Guardians of the Galaxy, which would set off a chain reaction preventing Thanos from gathering all the stones.
One interesting storyline could be Spider - Man teaming up with the Avengers to fight a new super - villain that's a combination of different powers they've faced before. For example, a villain with the strength of the Hulk and the mind - control abilities of Loki.
