Perhaps in this fanfiction, Gamora and Peter discover a new power or weapon that could turn the tide of the war. They could stumble upon an ancient artifact on one of the planets they visit during the events of Infinity War. This new power or weapon could be something that only they can use together, due to their unique connection and abilities. They then use it to fight against Thanos and his army.
One possibility could be that they find a way to defeat Thanos together in a more strategic way. Maybe Gamora uses her knowledge of Thanos and his weaknesses to help Peter plan an ambush. Since Peter is known for his quick thinking and Gamora is a fierce warrior, their combined skills could be a powerful force.
They could have escaped Thanos' clutches earlier. If they had worked more closely together from the start, they might have noticed Thanos' trap sooner and found a way to avoid it. This would have changed the whole course of the Infinity War as Gamora wouldn't have been sacrificed and Peter would have had his full team intact.
The plot could revolve around Gamora's discovery of her pregnancy. She might initially be in shock but then decide to keep it a secret from most of the characters. She continues to fight alongside her comrades while trying to protect her unborn child. As the war progresses, she may start to show signs of pregnancy that are hard to hide, causing some of her allies to question her state.
In a fanfiction, Gamora's pregnancy could add an emotional layer to her relationship with Peter Quill. He could be overjoyed at the news, but also extremely fearful for her safety. Their interactions would be filled with a mix of hope for the future and dread of the impending war.
One alternate ending could have been that Doctor Strange saw a different future where all the heroes didn't have to sacrifice so much. Maybe he found a way to defeat Thanos without half of the universe being dusted. For example, he could have used the Time Stone in a more creative way to trap Thanos in a time loop or something similar.
In fanfiction, Loki and Thor could have formed an alliance with other unexpected characters during Infinity War. Maybe they would team up with the Guardians of the Galaxy in a different way. Loki could have used his knowledge of the cosmos and his ability to blend in to gather more information about Thanos' plans. Thor could have shared his Asgardian battle strategies with Star - Lord and the others. This would have led to a completely different dynamic in the fight against Thanos, perhaps even resulting in a victory that didn't happen in the movie.
One possibility could be that Natasha's pregnancy added a new layer of vulnerability. It might have made her more cautious in battles, changing the dynamics of the Avengers' fight. For example, she could have been more hesitant to take on high - risk missions, leading to different strategic decisions within the team.
The child in fanfiction could potentially have some sort of special power. Maybe it could inherit Peter's ability to hold an Infinity Stone (if we consider that as a latent power) and Gamora's enhanced physical abilities. It would be raised in a universe full of danger and wonder. It could befriend the other Guardians and learn from them. This child might also struggle with the legacy of its parents, having to live up to their great reputations while also carving out its own path in the galaxy.
One possible plot could be that Peter Parker and Gamora are brought together by some cosmic event. Maybe they end up on a strange planet and have to team up to survive. They each bring their unique skills, with Peter's spidey - sense and acrobatic abilities, and Gamora's combat skills. They start off not trusting each other much, but as they face various challenges like dangerous alien creatures and harsh environmental conditions, they gradually learn to rely on one another and form a deep friendship.
Yes, there are likely many fanfics about Peter in Infinity War. Fanfiction writers often focus on characters like Peter and create their own stories set within the events of Infinity War. These can range from exploring his relationships with other characters, like Tony Stark, to imagining different outcomes for his role in the battle.
In this kind of fanfiction, Peter Parker might use time travel to prevent the events of Infinity War. Maybe he could go back in time to warn the Avengers about Thanos' plan earlier. This could lead to a completely different outcome, like they could gather more powerful forces or find a way to stop Thanos from getting all the Infinity Stones in the first place.
