Perhaps they could have used time travel to team up with alternate versions of themselves. So, the Avengers from different timelines could combine their powers and knowledge to come up with a better plan to stop Thanos. This would involve not just fighting him physically but also outsmarting him in terms of his knowledge of the Infinity Stones.
One interesting plot could be that the Avengers travel back in time to stop Thanos from ever being born. This would be a radical approach but could potentially solve the problem once and for all. They would have to deal with the moral implications of changing the timeline in such a major way.
Maybe they could use the Quantum Realm not just for time travel but also to create some sort of energy wave that counteracts the effects of the Snap. The characters in the fanfiction could figure out a way to harness the unique properties of the Quantum Realm, which is already a bit of a mystery in the MCU, to fix what Thanos did.
If Iron Man time - traveled in an Avengers Infinity War time travel fanfiction, he might use his tech - savvy skills to outwit Thanos much earlier. Maybe he could prevent the Snap from ever happening by going back and sabotaging Thanos' plan to collect the Infinity Stones.
In most cases, it is legal. Fanfiction is a form of creative expression by fans. As long as it doesn't violate any copyright laws in a major way, like using the exact same footage from the trailer without permission in a way that undermines the original work's marketability. But if it's on a legitimate platform that respects intellectual property, you should be okay.
One inspiration could be to focus on an original character's unique abilities. For example, if your OC has the power to manipulate time, they could be in a race against it during the events of Infinity War. They might try to stop Thanos before he gets all the Infinity Stones by using their time - altering powers in creative ways.
There could be some minor risks. For example, the quality of fanfiction can vary greatly. Some might have poor grammar or be poorly written, which can make the reading experience not so great. However, this isn't a major risk as you can always stop reading if it's not up to your standards.
It could have added an interesting dynamic. Venom's unique powers and personality might have thrown some unexpected twists into the plot of Infinity War.
Well, in this fanfiction scenario, if Wanda could reverse the snap, it would be a game - changer. Vision was a key part of her life, and her love for him could fuel this power. But it wouldn't be easy. There would be a huge energy cost, and she might have to sacrifice something in return. Maybe she'd have to give up some of her own life force. And then there's the matter of Thanos. He wouldn't just stand by and let her undo his 'work'. There would be a massive battle, and the outcome would be uncertain.
In Fate fanfiction with time travel during the 100 Years War, it's important to consider the rules of time travel in the Fate universe. If it's a type of time travel where changes are allowed, then a time - traveler could potentially bring modern weapons or knowledge. This could give an unfair advantage to one side. However, if it's a more 'fixed - timeline' type of time travel, the traveler might be forced to just observe and their presence could still have an impact on the psychological state of the soldiers, which in turn could affect the war in unexpected ways.
