Tony Stark could act as a mentor. He could teach the younglings in Westeros about science and innovation. For instance, he could show them how to build simple machines or use basic engineering principles to improve their daily lives. This would be a new concept in a world that is mostly focused on magic and swordsmanship.
Perhaps Tony Stark would be a diplomat. He could use his charm and intelligence to negotiate between the warring houses. He might also try to broker peace between the humans and the wildlings, using his understanding of different cultures (from his own world) to find common ground. His presence would add a whole new dimension to the complex political web of Westeros.
He could be a disruptor. His modern - day ideas and technology would disrupt the traditional ways of Westeros. He might introduce new forms of warfare, like using his repulsor rays instead of arrows.
In a Westeros fanfiction with Tony Stark, he could potentially form alliances. For example, he might team up with Daenerys Targaryen. His knowledge of engineering could help her build better defenses for her cities, or even improve the design of her dragons' saddles. Also, his charisma and leadership skills could influence the political landscape of Westeros in unexpected ways.
He would surely meet Black Panther. As the king of Wakanda, Black Panther would be the first and most important person Tony Stark would encounter.
His sense of humor would also play a role. He could use it to lighten the mood in tense situations within SHIELD. However, some agents might not appreciate his wisecracks all the time. For example, during a serious mission briefing, he might make a joke that some of the more serious - minded agents find inappropriate. But on the other hand, it could also help relieve stress for others.
Nebula can play the role of a catalyst. Her presence can push Tony to expand his thinking beyond Earth - bound problems. For example, if there's a story about Tony developing new space - friendly technology, Nebula's knowledge of different alien cultures and technology could be the trigger that sets him on that path.
He might become more power - hungry. Usually, he is a hero, but with the goal of taking over the world, he could lose some of his moral compass.
He might become more cautious. In the DC Universe, there are a lot of powerful and unpredictable entities. So, he could tone down his cocky side a bit.
In fanfiction, Tony Stark's smile can be a plot device. It might signal to other characters that he's up to something. For example, his sly smile could mean he has a clever strategy in mind.
It could be really exciting. Picture Tony Stark with his high - tech Iron Man suit in the middle of a Supernatural - style hunt. He might use his suit's sensors to detect supernatural entities instead of just regular threats. And the Winchesters would be both amazed and a bit skeptical of his high - tech ways.
Tony Stark is very confident and self - assured. As Harry Potter, this would make him a more assertive protagonist. He might not be as hesitant as the original Harry in some situations. For example, when facing Voldemort, he would likely be more direct and less fearful. His quick - thinking nature would also speed up the plot. Instead of waiting for things to happen, he would be more proactive in finding solutions to the problems in the wizarding world.
In this fanfiction, Tony Stark's character would develop in several ways. Initially, he might be a bit clumsy at parenting, but as time goes on, he'd become more attuned to Peter's needs. His focus would shift from just his own inventions and heroics to also considering Peter's future. He'd become more selfless, as he'd be willing to sacrifice his time and resources for Peter's well - being. He might also become more cautious in his actions, knowing that he has a young life depending on him.
