In this kind of fanfic scenario, the entire plot of the MCU could have been drastically different. For example, the remaining Avengers would have lost one of their most powerful members. Thor's strength and his ability to wield Stormbreaker were crucial in the actual Infinity War. Without him, the battle against Thanos on Wakanda might have been a total disaster much sooner. His death could have also deeply affected the morale of the other heroes, perhaps leading to different alliances and strategies that we didn't see in the original storyline.
She could simply overpower Thanos. Captain Marvel has shown incredible strength, so she might be able to directly take on Thanos and win in a one - on - one fight, preventing him from snapping his fingers.
One interesting concept could be how an original character (OC) interacts with Thor during the events of Infinity War. Maybe the OC has a unique power that helps Thor in his quest against Thanos, like being able to manipulate time briefly to give Thor an advantage in a battle.
Maybe an alien from a planet that was previously unmentioned in the MCU. This alien OC has a special connection to the power of the Infinity Stones and teams up with Thor because they realize that Thor is a key figure in the battle against Thanos. Their knowledge of the Stones could be crucial in the fight.
Definitely Iron Man. His relationship with Thanos is a big part of the story so far. Captain Marvel, who is extremely powerful, will be a key player as well. She has the strength to take on Thanos head - on. The Hulk might also be important. He was sort of absent in Infinity War, and in Part 2, he could come back with a vengeance, using his brute strength to fight Thanos and his minions.
Thanos is a key character as he is the main antagonist driving the story with his pursuit of the Infinity Stones. The Avengers like Iron Man, Captain America, and Thor are also key. Hulk plays an important role too.
The main plot points include Thanos' quest for the Infinity Stones. He travels across the universe to gather them all, believing that by using their power to wipe out half of all life, he can bring balance. The Avengers and other heroes try to stop him. There are epic battles across different planets and realms.
It sets the stage for the events of Infinity War. It might introduce characters' backstories, their current situations, and the looming threat that Thanos represents.
Well, I think the story will focus on the heroes' journey to reverse what Thanos has done. They might search for the Infinity Stones again, or find a way to use the remaining power they have to counter Thanos' snap. There could be new characters introduced who have some special abilities or knowledge to help in this fight. Also, the relationships between the heroes will be further explored, like how they deal with the loss and trauma from the first part.
