Well, it could be that the Avengers are just too focused on their own tasks and missions. They might not be paying close enough attention to Tony's behavior. Maybe they assume that Iron Man is just some other superhero out there and don't consider that it could be one of their own. Another reason could be that Tony has some sort of cover - up story for his absences when he's off being Iron Man. He could be telling the Avengers that he's working on other projects or taking some personal time, so they don't question where he really is.
One possibility is that Tony is extremely good at keeping his identity a secret. He might have used advanced technology to disguise his Iron Man activities so that the Avengers don't notice any connection. For example, he could have created hidden bases and used undetectable communication channels. Also, Tony may act so differently as Iron Man compared to his normal self around the Avengers that they just don't suspect it's him. He might be more confident and bold as Iron Man, while being more laid - back and sarcastic as Tony Stark among the team.
One consequence could be a lack of trust if the truth ever comes out. The Avengers might feel betrayed that Tony kept such a big secret from them. Another consequence is that Tony might be putting himself in more danger by not having the full support of the Avengers. As Iron Man, he could face threats that the Avengers could help with, but since they don't know, he has to deal with them alone.
Well, they might react to Tony Stark's self - destructive behavior. Maybe Thor would be amused by the technology, seeing it as primitive compared to Asgard's. And Natasha could be analyzing every move for potential threats or weaknesses in Stark's armor.
Well, they might be really excited. They could be commenting on all the new gadgets Iron Man seems to have in the trailer. Maybe Thor would be a bit confused by some of the high - tech stuff, while Black Widow would be analyzing every move Iron Man makes for strategic purposes.
Well, Peter could also use his intelligence to create false alibis. Whenever there's an incident where Spider - Man is involved at the same time Peter should be somewhere else, he has a well - thought - out excuse ready. He might say he was at a study group or helping an old neighbor, and since he's known as a smart and helpful kid, the Avengers would be less likely to suspect him.
In a fanfiction scenario, it could be part of a plot to create some drama. Maybe there's a villain who has a mind - control device and made them forget on purpose. This would lead to Tony feeling hurt and left out, which could then drive the story forward as the Avengers try to make it up to him and also deal with the threat of the villain.
If the Avengers were to watch 'Iron Man 1' in a fanfiction, it would be a unique experience. Tony Stark's journey in the movie is quite remarkable. The Avengers might see his early cockiness and be reminded of their own flaws. For example, Tony's decision to build the suit in a cave could inspire them in their own battles. They might also tease Tony about his early hairstyle or some of the cheesy lines in the movie. It could be a moment of bonding for the team as they watch and relive Tony's first steps into becoming Iron Man.
Well, it could be a really interesting scenario. Firstly, they would likely be curious about how the fanfiction portrays them. For Tony, he'd be in for a wild ride seeing all the different interpretations of his character in Iron Man 3. Natasha might analyze it from a psychological perspective, trying to figure out what makes the fan writers create such stories. Clint could be just there for the entertainment value, cracking jokes about the more out - there plot points. And Bruce, he might be a bit worried about how his character is depicted, especially if there are any Hulk - related elements in the fanfiction. All in all, it would be a unique experience for the Avengers to peek into the world of fan - created stories about Iron Man 3.
In a fanfiction where Tony didn't die, he could continue to be a mentor to the new generation of Avengers. He would use his genius intellect to develop even more advanced technology to protect the Earth. Maybe he'd finally have the time to focus on his family life with Pepper and their daughter, while still being involved in superhero affairs on a more strategic level.
In some fanfictions, it could start with Spider - Man accidentally getting involved in an Avengers - level threat. He manages to hold his own and even helps them out a bit. Impressed by his performance, the Avengers then start to consider recruiting him. They might send one of their members, like Iron Man, to have a talk with Spider - Man, highlighting the benefits of joining the team, such as access to better resources and more global protection opportunities.
In fanfiction, perhaps Tony would use his genius to create a special prenatal care system for Pepper. It could be something that uses his Iron Man technology to ensure the healthiest pregnancy possible. He might even be able to detect any potential problems long before traditional medical methods.
