Well, in this fanfic, maybe Naruto's chakra is mistaken for an Infinity Stone - like a new, unknown power source. The Avengers, being intrigued, try to understand it. Meanwhile, Naruto, upon learning about Thanos' plan, decides to use his Sage Mode to track Thanos down. He teams up with Iron Man, and they come up with a plan that combines Naruto's ninjutsu and Iron Man's technology to take on Thanos and his minions.
The fanfic could start with Naruto already in the Marvel universe before the events of Infinity War. He has been living there in secret, training and honing his skills. When Thanos starts his quest for the Infinity Stones, Naruto steps forward. He forms an unlikely bond with Thor, as they both have experience with powerful weapons (Naruto's kunai and Thor's hammer). Together with the other Avengers, they fight against Thanos. Naruto uses his Nine - Tails chakra to give the Avengers an edge in the battles, especially when facing Thanos' powerful attacks.
Well, Naruto characters have unique abilities. For example, Naruto's shadow clones could be used for various strategies. Sasuke's Sharingan could detect hidden threats. They could join the Avengers to fight against Thanos. Maybe Naruto's Rasengan combined with Iron Man's repulsor technology could create a super - powerful attack.
A plot might also revolve around the villains. Some villains might see the chaos as an opportunity to take over. The Avengers would then have to deal with new threats while still recovering from the events of Infinity War. The fanfic could show how they come up with new strategies and alliances to face these challenges.
The sequel story could focus on the emotional and psychological aftermath of the Snap on the surviving characters. Tony Stark, for example, might struggle with guilt for not being able to stop Thanos. Meanwhile, Captain America could be trying to keep the remaining Avengers united. And then, they get a glimmer of hope in the form of a prophecy that leads them on a quest to save the universe.
The story of Avengers Infinity War Part 2 might revolve around the emotional and physical recovery of the surviving heroes. They would be dealing with the guilt and grief of losing so many. Captain America could lead the way in rallying the troops. They might discover a hidden power within themselves or find an unexpected ally, like a powerful cosmic entity. This newfound strength or help would be the key to their fight against Thanos. They would then have to figure out how to take on Thanos' army and overpower him, not just in terms of strength but also in strategy. It would be a long and arduous journey filled with self - discovery and teamwork.
An interesting crossover could be that the Infinity Stones are actually ancient ninja artifacts lost in another dimension. Naruto and his friends are sent to the Marvel universe to retrieve them. Along the way, they meet the Avengers and team up. They have to learn to use each other's powers and fight off Thanos who wants the stones for his own evil purposes.
One possible plot could be the Avengers watching the events unfold in Infinity War and constantly making comments about their own actions. For example, Thor might be yelling at his past self for not going for the head when he had the chance against Thanos. They could also be strategizing on how they could have changed the outcome, leading to some interesting in - group debates and revelations about their relationships with each other.
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.
A fanfic could be centered around the younger Avengers like Peter Parker and Shuri. When they watch the Infinity War trailer with the rest of the team, Peter is in awe and can't stop talking about how cool it all looks. Shuri, on the other hand, is analyzing the technology shown in the trailer and starts giving ideas on how to improve their own gear. The older Avengers are both amused and impressed by their enthusiasm, and it brings a sense of hope and unity to the group as they face the impending threat shown in the trailer.
Well, a great plot could be that the Infinity Stones start to mess with the fabric of reality and it creates a portal between the Naruto universe and the Marvel universe. The Avengers and Naruto's friends end up in each other's worlds. Naruto and the Avengers have to work together to fix the portals and return everyone to their proper universes. Along the way, Naruto might have some epic battles with villains like Loki, using his ninja speed and strength. And the Avengers could learn a thing or two about chakra from Naruto and his friends.
Definitely Naruto and Doctor Strange. Naruto with his unique ninja abilities and Doctor Strange with his magic. They could exchange knowledge about different forms of power and combat techniques. Maybe Naruto could learn some new ways to manipulate space - time from Doctor Strange, and Doctor Strange could be fascinated by Naruto's chakra control.
