One possible reason could be that Shield has been corrupted from within. Maybe Tony discovers some dark secrets or unethical practices within Shield that make him believe it's a threat that needs to be eliminated. For example, if Shield was involved in illegal human experimentation or was secretly working with enemies of the state.
It could also be a matter of ideology. Tony might have realized that Shield's methods and goals are no longer in line with what he believes is right for the safety and future of the world. He may think that Shield has become too powerful and unaccountable, and destroying it is the only way to start anew and build a better security system.
Another way could be through hacking. Tony is a genius when it comes to technology. He could hack into Shield's systems and cause widespread chaos, like shutting down their communication networks, power sources, and defense mechanisms, which would ultimately lead to the destruction of Shield as an organization.
One implication could be a major shift in the technology and operations of Shield. Tony Stark is known for his advanced tech, so Shield might become more high - tech under his ownership. For example, better security systems and more advanced weaponry.
One possible plot could be Tony Stark completely revolutionizing SHIELD's technology. He'd bring in his Iron Man suits' advanced tech, making SHIELD's weapons and defense systems far more powerful. For example, he might develop new types of energy shields inspired by his suit's defenses.
There might be a fanfiction where Tony Stark has a conflict with Shield over the use of his technology. He could be worried that Shield might misuse his Iron Man suits or other inventions. This could lead to a tense stand - off and a series of events that test their relationship.
In some fanfictions, Tony Stark might come to own Shield through his financial power and technological superiority. He could use his vast wealth to buy out the organization or find a way to take over its assets during a time of crisis when Shield is in need of a major overhaul or rescue.
Well, if Tony Stark takes over SHIELD in fanfiction, one of the first things he'd probably do is bring in his own team of trusted allies. People like Pepper Potts might get involved in the administrative side of things, bringing a more business - minded approach to SHIELD's management. He would also likely use his vast resources to fund new projects within SHIELD. For example, he could start research on new types of energy sources for their weapons and technology. And in terms of international relations, Stark's takeover could change how SHIELD interacts with other countries. His global influence as Iron Man might make some countries more or less cooperative with SHIELD depending on their previous relationships with him.
One reason could be that he's frustrated with the leadership or the direction the Avengers are taking in the fanfiction. He might feel his ideas are not being heard.
Guilt. For example, if he fails to save someone he cares about. He'll feel responsible and that could lead to him crying.
In fanfiction, emotional distress can also be a factor. If something really bad happens, like the loss of a loved one or the destruction of his work that he has put so much effort into, the shock and grief could be so overwhelming that he faints. Additionally, he could be suffering from some hidden illness that flares up suddenly and causes him to faint.
One possible reason could be that Tony Stark is being overly critical of Peter's superhero work. Maybe Peter made a big mistake during a mission, and Tony's harsh words in his attempt to correct Peter made him cry. For example, if Peter accidentally put civilians in danger and Tony scolded him severely.
