A plotline could involve Tony Stark joining Hydra to spy on them for the Avengers. He pretends to be on their side, but secretly feeds information back to his old team. Along the way, he has to be careful not to get caught and also has to deal with Hydra members who start to suspect him. This would create a lot of suspense and action in the fanfiction. Also, there could be a plot where Tony tries to change Hydra's ideology from within, using his charm and intelligence, but it turns out to be a much harder task than he thought.
Well, if Tony Stark joins Hydra in fanfiction, it would be a total chaos. His high - tech gadgets and genius mind would be a huge asset for Hydra. But his moral compass, which is usually in line with the Avengers, would be seriously conflicted. Maybe he would try to reform Hydra from the inside, using their resources for good. Or he could be brainwashed into doing really evil things at first until he snaps out of it.
Well, there are several common themes. Resistance is one. Tony Stark is a strong - willed character, and in these fanfictions, he usually resists Hydra's attempts to take over or manipulate him. Also, the exploration of power is common. How Hydra wants to use Stark's power, and how he uses his power to fight back. And secrecy, as Hydra operates in the shadows and Stark has to uncover their plots.
In this scenario, it would be a complete shocker. Tony Stark is a hero, and Thanos is a villain. If he were to join Thanos, it might be because Thanos somehow convinced him that his plan was for the greater good. Maybe Thanos showed him a future where overpopulation and resource depletion were so bad that his 'snap' was the only solution. But this would go against everything Stark stands for, so it would be a very complex and dark turn for his character.
Sure. There is. A lot of fanfiction writers like to take the idea of Hydra and insert it into the world of Tony Stark. You might come across stories where Hydra tries to manipulate Stark's Iron Man technology for their own evil purposes. It's a great way to see different interpretations of the characters and how they would interact in these new and often darker situations.
One possible plotline could be that Tony Stark uses his genius to find an alternative way to defeat Thanos without sacrificing himself. Maybe he discovers a new element or technology during the final battle that turns the tide. Another plotline could involve time travel having unforeseen consequences that bring Tony back to life in a different timeline, and he has to find his way back to his original one.
A possible plotline could be them having to keep their marriage a secret from the world. Maybe because of Tony's business rivals or Natasha's undercover work. They would have to navigate their relationship while hiding it from everyone, which could lead to some really tense and exciting moments.
One possible plotline could be that a powerful magical spell in the Harry Potter universe somehow crosses over and affects Tony Stark, causing the mpreg situation. Then, the story could revolve around Tony trying to figure out what happened and how to reverse it, with Harry Potter characters helping or hindering him. Another plotline might be that a new form of technology in Tony Stark's world has an unexpected side effect when combined with the magic of Harry Potter's world, leading to the mpreg. And the characters have to find a way to deal with the social and magical/technological implications.
One possible plotline could be that Tony Stark sees a future where his technology is misused and he has to find a way to prevent it. For example, he might see his Iron Man suits being used for evil purposes by a powerful villain. Another could be that he sees a future without him, and realizes the importance of training a successor, like Peter Parker, more seriously. Or he could see a future where the Avengers are disbanded due to internal conflicts, and he tries to mend the relationships in the present to avoid that future.
Perhaps there's a power struggle over a new technology or a powerful artifact. Tony wants to use it for what he believes is the greater good, but Steve opposes him. Their clash escalates to a point where Tony, in a fit of rage or desperation, kills Steve. Or maybe it's a situation where Steve discovers some dark secret about Tony's business dealings and Tony kills him to keep it quiet.
In such a fanfiction, the plot might involve Hydra using Tony for his technological genius. They could force him to create advanced weapons for their evil purposes. Maybe they'd try to extract the secrets of the Iron Man suit technology. Another aspect could be Tony's attempts to escape while also trying to figure out Hydra's larger plan and find a way to stop them from within their lair.
