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.
In fanfiction, their interactions can also be very tense. Tony might try to use his sarcasm and intelligence to taunt Thanos, while Thanos, with his calm and collected demeanor, would simply brush it off. Sometimes, Thanos might even admire Tony's tenacity in the face of such overwhelming power, which could lead to some interesting exchanges between them.
One interesting Thanos and Tony Stark fanfiction could be where they have to team up against an even greater threat in the universe. Maybe a new powerful alien race emerges that is set on destroying all life, and Thanos, with his knowledge of different planets and Tony Stark with his technological genius, are forced to put aside their differences. In this kind of story, we might see Tony trying to outwit Thanos at times while also learning from his vast experience in the cosmos.
In some fanfictions, Thanos and Tony Stark have a more personal connection. For example, Thanos has a past encounter with Howard Stark (Tony's father) that changes the whole dynamic. This could lead to a story where Thanos has a different view of Tony, and Tony has to grapple with this new information while trying to save the universe.
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.
Comic storylines are fluid. Thanos and Tony Stark's interactions vary. So, there's no standard way Thanos kills Stark. It could involve cosmic powers, strategic battles, or unexpected plot twists.
In some fanfictions, the relationship between Tony Stark and Thanos is explored through their interactions with other characters. For example, if Pepper Potts gets involved in some way, it could change how Tony approaches Thanos. Or if Thanos' daughters play a role, it might soften Thanos' stance towards Tony, leading to a more nuanced exploration of their relationship.
Tony Stark himself is often very well - written in these fanfictions. Writers can really explore his genius, his determination, and his flaws. Another great character can be Pepper Potts. In some fanfictions, she plays a crucial role in helping Tony, like providing him with moral support or even getting involved in the fight in some way. And of course, Thanos. A well - written Thanos in these fanfictions is truly menacing, with his complex motives and powerful abilities clearly shown.
Well, in some 'Tony Stark Fights Thanos' fanfiction, there's a plot where Tony manages to hack into Thanos' mind through some super - advanced tech he's developed.

He uses all his suit's power and some experimental tech to send Thanos into a different dimension or something like that, saving the universe at the cost of his own life.
