Well, one possible plot could be that Naruto grows up in the Marvel universe with Tony Stark as his father. He might inherit some of Stark's technological genius along with his own ninja skills. Maybe he uses his chakra to power up some of Stark's suits in unique ways, creating a new kind of superhero hybrid.
There could be a plot where Tony's past mistakes come back to haunt him, and he's worried about how it will affect Peter. He might try to distance himself from Peter to protect him, but Peter doesn't understand and feels rejected. This would lead to a rift between them. However, in the end, they would reconcile as they realize how much they mean to each other as father and son.
Yes, in certain fanfiction stories. This concept can bring a lot of changes to the existing Marvel narrative. For example, it could change how Peter inherits Stark's technology. Instead of just being a mentee, he could be the rightful heir. It also might affect how other characters interact with Peter. They could view him as more of a significant figure in the Stark legacy, and it could create more complex story arcs involving family secrets and power inheritance.
One plotline could be Peter dealing with the expectations of being Stark's son. Everyone would expect him to be a genius like his father, and he'd have to prove himself. Another is him using Stark's resources to upgrade his web - slinging abilities in unique ways. Maybe he creates web - shooters that can analyze and counter any enemy attack.
A key element is the mentorship aspect evolving into a father - son bond. Tony guiding Peter in his superhero journey, like teaching him combat strategies or how to use advanced technology. Another element is the emotional connection. For instance, Peter looking to Tony for approval and Tony feeling a sense of pride when Peter succeeds.
Maybe he's too caught up in his work. Tony Stark is often depicted as a workaholic, so he could be so focused on his inventions and saving the world that he simply doesn't have time for his son.
His powers would be really interesting. He could use his magic to enhance the technology he inherits from Stark. For instance, he could make his Iron Man suit invisible using a disillusionment charm. He'd also have an edge in combat as he could use both magic and technology. His spell - casting ability could be used to hack into computer systems or disable enemy technology. And his knowledge of the wizarding world would give him an advantage in dealing with threats that are both magical and technological in nature.
In a lot of fanfiction, the concept of Tony Stark as a technopath is used to enhance his already brilliant technological mind. It gives him a sort of superpower within the context of the story. This can lead to all kinds of exciting plot developments, like him being able to instantly diagnose and fix complex technological problems just by thinking about them. It also allows for some really creative interactions between him and other characters who may be in awe of this ability.
