One good example could be a fanfiction where Tony Stark's secret identity is at risk when a new villain has some sort of technology that can detect his hidden identity. In this story, Pepper Potts might play a crucial role in protecting his secret, perhaps by creating false leads or using her business connections to throw the villain off track. Another example could be a fanfiction set in an alternate universe where Tony's secret identity is known only to a select few, like Rhodey and Happy, and they have to deal with the consequences of a leak within this small group.
If Tony's secret identity in fanfiction is kept from a new love interest, it can create a lot of drama. When the truth eventually comes out, the love interest may feel betrayed, thinking that Tony didn't trust them enough. On the other hand, if his friends like Happy find out about a new threat to his secret identity, it can strengthen their bond as they work together to protect it.
In Spider - Man secret identity fanfiction, often new characters are introduced that are somehow related to his secret. Maybe a new villain who has figured out his identity and is using it to blackmail him. This can lead to really interesting story arcs where Spider - Man has to not only fight the bad guys physically but also protect his identity at all costs.
Iron Man's identity concealment varies throughout the comics. Initially, he was secretive, but eventually, it was no longer a hidden fact. This shift impacted his relationships and the challenges he faced.
The mystery. We all know Spider - Man has a secret identity, but in fanfiction, authors can take that mystery to new levels. They can create scenarios where his identity is on the verge of being exposed in the most unexpected ways.
One way could be through a technological fix. Maybe in the fanfiction, some super - advanced alien tech falls into Iron Man's hands. He then uses his genius to integrate it into his suit, fixing any previous glitches or weaknesses. For example, if his power source was running low or unstable, this new tech could provide a more efficient and long - lasting power solution.
