Captain America could be initially shocked but then determined to help. He might try to talk to Tony about his own experiences of loss and how he found the strength to keep going. He'd probably encourage Tony to see that he's not alone in his struggles.
Pepper might be completely devastated. She could be by his side constantly, trying to bring him back to a better mental state. She might use her love for him and remind him of all the good he has done and all the people who still need him.
One possible reason could be the extreme guilt he feels over the consequences of his inventions. In many stories, his tech has been misused, causing destruction and loss of lives. He might feel like he's responsible for all the chaos and that there's no way to fix it, leading to a suicide attempt.
I would rather not recommend specific tony stark suicide fanfiction. It's a very negative and disturbing concept. Instead, there are a lot of great fanfictions that focus on his heroic deeds, his relationships, and his technological genius. For example, some fanfictions explore his adventures with the Avengers or his new inventions, which are much more positive and enjoyable to read.
The existence of tony stark suicide fanfiction might be due to a few factors. Firstly, it could be a creative exploration of the character's psychological state. Tony Stark was often in high - stress situations, and writers may want to see how far his mental state could be pushed. Secondly, in the context of the complex Marvel storylines, some might use it to show the consequences of certain events on his mental health. However, this type of fanfiction is not for everyone as it can be quite dark and may not align with the more positive aspects of the character that most fans enjoy.
One common character paired with him is Bruce Banner. They could be gaming buddies, with Bruce using his scientific knowledge to help Tony improve his games or vice versa. Another is Pepper Potts. She might be shown as someone who tries to get Tony to take a break from his intense gaming sessions.
Some fanfictions may also use Tim Drake's suicide attempt to comment on larger themes like mental health in the superhero world. It shows that even heroes, who seem invincible on the outside, can struggle with inner demons. By exploring this, fanfiction writers can create more complex and relatable versions of the character.
His parents, Howard and Maria Stark, are very common. They play important roles in shaping Tony's childhood. Jarvis, the family butler, also often appears. He could be the one to encourage Tony's scientific pursuits or keep him out of too much trouble.
One common character paired with him could be Pepper Potts. Their relationship could be explored in a new light with Tony having psionic powers. Maybe Pepper has to deal with a more powerful and sometimes unpredictable Tony.
He'd probably be shocked at first. Tony is always so caught up in his own world that a secret daughter would be a huge surprise. But then he'd likely be protective. He might try to keep her away from his dangerous life at first, but as he gets to know her, he'd start to include her in things.
The Avengers would be in a state of panic and fury. Captain America would likely lead the charge to find Tony. He'd use his military strategy skills to plan a rescue mission. Thor might use his godly powers to track down any signs of Tony's whereabouts. Black Widow and Hawkeye would be on the lookout for any Hydra agents or informants. Hulk could be a wildcard. He might be uncontrollably angry and ready to smash anything in his path to get to Tony.
He would probably be overprotective at first. Tony has been through a lot, and the idea of his daughter having mutant powers, which could make her a target, would be scary for him. He might try to keep her locked away in the Stark Tower, but that would likely lead to her rebelling.
