A really interesting plot could be based on the idea of time travel within the context of 'The Avengers Infinity Wars' fanfiction. What if the Avengers found a way to go back in time and change certain events that led to Thanos getting the Infinity Stones? They could try to prevent the destruction of Xandar where the Power Stone was first retrieved, or stop Loki from stealing the Tesseract on Earth, which was a crucial step in Thanos' plan.
Another plot could focus on the relationship between Thanos and his adopted daughters in a more in - depth way in the context of the Infinity Wars. Maybe there was a time when they were planning a rebellion against him before he even started his quest for the Stones. This could add a whole new layer of backstory and drama to the events of the movie.
One idea could be exploring what if a minor character from the movie got the Infinity Stones instead. For example, a random Asgardian warrior. They might use the power in a completely different way, perhaps trying to restore Asgard rather than the more universal aims Thanos had.
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.
One idea could be that in the fanfiction, instead of Thanos getting all the Infinity Stones, the Avengers manage to steal some of them first. They could then use the power of the stones they have to create alternate versions of themselves to fight on different fronts against Thanos' forces.
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.
One plot idea could be that the Avengers are somehow transported to the Star Wars universe. They have to team up with the Jedi or the Rebels to fight a common enemy, like a new Sith Lord who has powers similar to some of the Avengers' villains. Another idea is that the Infinity Stones are discovered in the Star Wars galaxy and both the Avengers and Star Wars characters have to figure out what to do with them.
One idea could be exploring the backstories of the characters in more depth before the events of the trailer. For example, you could write about Thor's journey after losing his eye and how it led him to where he is in the trailer. Another idea is to create a different perspective on the villain, Thanos. Maybe show his internal struggle or his reasons for wanting the Infinity Stones that are a bit more complex than just pure evil. You could also focus on the relationships between the Avengers, like how Iron Man and Captain America might have reconciled off - screen before coming together to face Thanos.
Well, in some 'Avengers watching Infinity War' fanfictions, there are really cool character interactions. Like Iron Man and Captain America might finally have a heart - to - heart about their differences during the movie events. And Hulk could be super embarrassed about not coming out when Banner wanted him to. Also, the way the characters deal with the emotional moments, like when Vision is killed, can be explored in new and different ways in fanfiction.
One idea could be exploring what would happen if a minor character from the movie got the Infinity Stones instead of Thanos. For example, a Wakandan scientist. They might use the stones for completely different purposes like enhancing the technology of Wakanda even further, which could have a huge impact on the entire universe in the fan fiction.
Well, imagine Thanos in the Star Wars universe. He could be a Sith - like figure, trying to gather all the kyber crystals (akin to the Infinity Stones). The Avengers could team up with the Jedi to stop him. The Hulk could be like a Wookiee in terms of his brute strength, and Thor's hammer could be seen as a sort of lightsaber - like weapon in the Star Wars aesthetic. There are so many possibilities for these two universes to collide in fanfiction.
