Well, Tony might form a new relationship with Vision. In the original story, Tony's losses influenced his creation of Vision to some extent. But if he didn't lose anyone, this relationship could start from a different place. Maybe they would bond over the exploration of new technology and knowledge without the shadow of Tony's past. He could also form a more positive relationship with Fury. Often, Tony's actions after his losses put him at odds with Fury at times. But without those losses, they could work together more smoothly, with Tony being more compliant and Fury seeing him as a more stable asset to the team.
He could form a more relaxed friendship with Thor. Without the burden of loss, Tony could engage with Thor on a more fun level, like they could have more friendly competitions about technology vs magic. He might also build a closer bond with Natasha. Normally, his losses make him a bit standoffish at times, but here he could be more open to her friendship, perhaps sharing his ideas more freely without the fear of being judged based on his past traumas.
Well, in some fanfictions, the writers might choose to focus on other aspects of Tony's story rather than his losses. They could be more interested in his technological achievements or his relationships that are not centered around loss. For example, they might explore his friendship with Bruce in a way that doesn't touch on any losses Tony might have experienced.
If the Avengers think Tony didn't lose anyone in fanfiction, it could make Tony seem more of an enigma to them. They would expect him to be more jovial and less guarded. This would change how the Avengers approach him. They might be more likely to include him in more light - hearted activities or missions. His decisions would also be perceived differently. For instance, if he decides to fund a project, it wouldn't be seen as a way to prevent future losses like in the original story, but rather just a business or innovation decision. This could lead to a very different kind of Avengers team, where Tony is more of an uncomplicated figure in their eyes.
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.
Yes, there are likely fanfictions out there with such a plot. Fanfiction writers often explore different dark and angsty scenarios for their favorite characters. However, I can't specifically point you to one as there are countless fanfictions in the Avengers fandom.
Differences in ideology can also play a part. Tony might have some views on how to handle threats or use technology that the other Avengers don't agree with. Maybe he's more willing to take risks with untested tech that could endanger the team or civilians, which would lead to resentment.
One great aspect of fanfiction involving Tony and T'Challa could be their different technological approaches coming together. Tony is all about high - tech, flashy Iron Man suits and advanced weaponry. T'Challa, on the other hand, has the advanced Wakandan technology which is more rooted in tradition and secrecy. In a fanfiction, they could collaborate on a project to upgrade the Avengers' technology while also respecting Wakandan traditions. For example, they might combine Tony's miniaturization techniques with Wakandan vibranium - based energy sources to create a new kind of power cell for the Avengers' equipment.
Tony may be initially skeptical. He's used to the official Avengers narrative. But if he delves into the Avengers documentary fanfiction, he might be surprised. Some fanfiction could provide in - depth analysis and alternative viewpoints that he hadn't considered before. He could end up respecting the creativity of the fans who write it, even if he doesn't agree with all of it. Maybe he'd see it as a way to expand the Avengers' lore in a non - official but still engaging way.
Perhaps it's due to personal relationships. He might have had a falling - out with one or more of the other Avengers. Like if there were misunderstandings or betrayals. In some fanfictions, a conflict with Steve over leadership or ideological differences could lead to Tony leaving the team.
One possible plot could be that Tony makes a great sacrifice during a battle but the Avengers, due to some mind - altering spell or extreme shock, forget all about him. Tony wakes up alone, injured, and has to figure out how to deal with his new situation while also trying to find a way to make the Avengers remember him again.
If Tony didn't die, the story would be drastically different. For one, the Avengers would still have his leadership and resources. His presence would change the dynamic during the post - Endgame events. They wouldn't be mourning his loss, but instead, be planning new strategies with him at the helm.
