Another aspect could be the emotional turmoil for the other Avengers. They would surely be scrambling to find Tony. Captain America might feel especially guilty, considering their past differences. The team would have to put aside their differences completely to rescue Tony. They might start by gathering intel on Thanos' whereabouts and formulating a plan that involves their unique skills. For example, Black Widow could use her espionage skills to infiltrate Thanos' base, while Thor could provide the brute force needed in a direct confrontation.
Yes, there are likely fanfictions out there where Tony kills Thanos. The Marvel universe has a huge fan base, and fans often create alternative storylines. Some might explore this scenario to give a different take on the Infinity War and Endgame stories.
Probably the other Avengers like Captain America. He could play a role in trying to save Tony or in the fight against Thanos that ultimately leads to Tony's death. Maybe Doctor Strange as well. Since he has knowledge of the future and the Infinity Stones, he might be involved in some way. He could either try to prevent Tony's death or his actions could inadvertently lead to it.
Tony would likely be defiant. He's not the type to cower in the face of danger. He might immediately start looking for weaknesses in Thanos' setup and try to escape on his own terms.
In Thanos Tony fanfiction, the theme of coexistence is sometimes present. Despite their differences, they might find a way to coexist in certain storylines. The exploration of their individual traumas is also a theme. Thanos has his own backstory that drives his actions, and Tony has his own set of traumas from his superhero journey. These traumas can shape their interactions in the fanfiction.
In this scenario, it would be a complete shocker. Tony Stark is a hero, and Thanos is a villain. If he were to join Thanos, it might be because Thanos somehow convinced him that his plan was for the greater good. Maybe Thanos showed him a future where overpopulation and resource depletion were so bad that his 'snap' was the only solution. But this would go against everything Stark stands for, so it would be a very complex and dark turn for his character.
Well, it could also lead to a rescue mission. The Avengers or other superheroes might find out about Peter's kidnapping. They would then come together to form a plan to rescue him. This could involve a lot of strategizing and fighting against Thanos' forces.
Peter would probably be scared at first. He's just a kid, after all, and being kidnapped by a powerful being like Thanos is terrifying. But he would also be defiant. He has a strong sense of responsibility, so he might try to find a way to escape on his own.
In fanfiction, their interactions can also be very tense. Tony might try to use his sarcasm and intelligence to taunt Thanos, while Thanos, with his calm and collected demeanor, would simply brush it off. Sometimes, Thanos might even admire Tony's tenacity in the face of such overwhelming power, which could lead to some interesting exchanges between them.
One common theme is identity. Tony has to figure out who he is with Thanos as his father. Another is the struggle between good and evil. Since Thanos is a well - known villain, Tony has to decide whether to follow in his father's footsteps or be a hero. And power is also a theme, as he may inherit some of Thanos' power.
