One interesting fanfiction could be where Tony Stark cries after realizing the true cost of his superhero lifestyle on his personal relationships. He might break down when he sees how his actions have pushed away Pepper or Rhodey.
In some fanfictions, Tony Stark might cry when he relives memories of his parents. Maybe he stumbles upon an old item that belonged to them, like his father's old watch, and it triggers a flood of emotions. He would be thinking about all the things he never got to say to them and the mistakes he made in his own life that he wishes he could have corrected before it was too late.
One possible scenario in such a fanfiction could be that Peter is crying because he misses Tony Stark after his death. Tony was like a mentor to Peter, and his absence leaves a huge void. Peter might be in the Avengers compound, looking at old photos or mementos of Tony, and the memories make him break down in tears.
One reason could be the loss of a close friend like Steve Rogers. Their complex relationship and the times they fought side by side, if Steve were to sacrifice himself, it would be a huge blow to Tony. He might cry out of grief and also regret for the times they had disagreements.
A reason could be that Peter is reminded of Tony's last words to him. Those words were full of hope and trust in Peter. When Peter reflects on them, he is overcome with emotion and starts to cry as he feels the weight of Tony's expectations.
One possible scenario in a fanfiction could be that Peter Parker is trying to hide his emotions from Tony Stark. Maybe he's been through a tough situation at school, like being bullied, but he doesn't want to seem weak in front of his mentor. Tony, on the other hand, has his own issues with showing vulnerability. He's always been the strong, confident Iron Man. But perhaps he starts to notice Peter's struggle and tries to open up about his own past traumas to encourage Peter to let it all out.
The author could describe it as a moment of complete vulnerability. His eyes might be red - rimmed, and his face contorted with pain. The sobs could be racking his body as he finally lets out all the pent - up emotions that he has been hiding for so long.
One great fanfiction about Tony Stark's father could be 'Howard's Legacy'. In this fic, it might explore Howard Stark's early days in building Stark Industries and how his decisions then affected Tony later. It could show Howard's relationships with other scientists and his vision for the future that Tony eventually inherits. Another interesting one could be 'Father and Son: Unseen Bonds' which might focus on the emotional connection between Howard and Tony that was not fully explored in the movies. It might include flashbacks of Howard teaching a young Tony about engineering and the values he wanted to pass on.
A really interesting 'Tony Stark Alone' fanfiction is when he's alone on an alien spaceship. He has to figure out how to navigate the ship, avoid the alien crew (if they're hostile), and find a way to communicate with Earth. It shows his skills not just as an engineer but also as a diplomat in a sense. He has to use his charm and intelligence to survive in a completely alien environment.
One interesting crossover could be Naruto using his chakra in Tony Stark's high - tech world. Maybe Naruto's ability to move at high speeds and his physical strength could be combined with Stark's suits. For example, Naruto could use his chakra to power up the suit's functions even more. Another aspect could be the cultural clash. Naruto, coming from a feudal - like ninja world, would have a different view on things compared to the modern and often self - centered Tony Stark. They could learn from each other's values.
One interesting storyline could be Tony Stark trying to break someone out of The Raft secretly. He might use his high - tech gadgets to bypass the security systems.
One interesting storyline could be Tony's early experiments in his father's workshop. He might be tinkering with small gadgets, getting in trouble for using expensive parts. Another could be his relationship with his parents at a young age, like how he coped with his father's high expectations.
