If Steve had come clean to Tony, it's likely that they would have had a deeper level of trust. This could have impacted the course of events in the fanfiction, allowing them to overcome challenges more effectively and creating a more harmonious narrative.
In this fanfiction, perhaps Steve and Bucky come across Tony when he's being bullied in school for being a genius. They see his potential but also his vulnerability. So, they adopt him. As time passes, Tony starts to show an interest in Steve's shield and Bucky's combat skills. They encourage his inquisitive nature. Steve cooks for them all, creating a homey atmosphere. Bucky teaches Tony how to deal with nightmares as he has his own experiences. And Tony, in turn, uses his intelligence to improve their living situation and help them in their own missions in some way.
At first, it might be a bit rocky. Tony, being used to his own space, might feel smothered by Steve and Bucky's over - protectiveness. But as time goes on, he'll start to see their good intentions. Steve's moral compass will inspire Tony to be a better person, and Bucky's loyalty will make Tony feel secure. Eventually, they'll become like a real family, with Tony looking up to Steve as a father figure and seeing Bucky as a cool older brother.
Perhaps in a post - Endgame world, Tony didn't die but lost his memory. Steve takes it upon himself to help Tony regain his memories. Along the way, they re - explore their relationship, the Avengers, and all the events that led to that point. Steve shows Tony videos and tells stories, and slowly Tony starts to remember, leading to a renewal of their friendship and a new start for the Avengers.
It could lead to all sorts of interesting plot developments. Maybe Tony would be surprised or intrigued.
They would probably have a very complex relationship. Steve, being the older and more traditional one, might try to instill his values in Tony. But Tony, with his independent streak, might rebel against it at times. They would also have a strong bond of family, with Steve being protective of Tony, and Tony looking up to Steve in some ways while also trying to make his own mark.
Some writers might want to explore dark and extreme scenarios. It's a way to break the norms of the usual heroic storylines. They may be interested in seeing how the characters and the Marvel universe would react to such a tragic event.
Well, if Tony wasn't there to assist, the balance of power would have shifted greatly in Thanos' favor. It's likely that the heroes would have faced more losses and the fate of the universe would have hung in the balance in a much more uncertain way.
Well, often they emphasize the strong bond between Tony and Steve. It might show their deep emotional connection and how they complement each other.
A common theme is friendship. Despite their differences, they always come back to being friends. For example, in many stories, they start off arguing but end up supporting each other.
Another characteristic is the exploration of their different powers and skills within the story. Steve's super - strength, Tony's high - tech gadgets and Peter's spider - like abilities are often used in creative ways to overcome obstacles. This can lead to really exciting action sequences.
