Tony could also be intrigued. Fanfiction often shows different perspectives on a person, and he might be interested in exploring what the writers have come up with. He might start discussing it with his friends or other people who are also fans of Skip, if there are any.
Another possibility is that Tony would be indifferent. If he's not really into the whole fanfiction thing or doesn't care much about Skip Westcott in that sense, he might just shrug it off and forget about it. However, if he has a strong opinion about Skip or the concept of fanfiction in general, his reaction could be more intense, either positive or negative.
Tony could be really surprised. Maybe he'll first be curious to read it and see what others have imagined about Skip Westcott in this fanfiction.
He could be shocked. Maybe he'd laugh it off if it was a funny or light - hearted fanfiction.
Tony might be really surprised. He could have a range of reactions from being amused to being a bit uncomfortable, depending on what the fanfiction is about.
If Zeus stumbles upon mal fanfiction, his reaction could be complex. He might initially be dismissive, thinking it's some strange human folly. But if it starts to gain popularity and he realizes it's making him look bad, he would be offended. Zeus is used to being in control and being seen as a powerful and just god. This mal fanfiction could make him look like a tyrant or a fool, which would go against his self - image. So, he may try to find a way to correct this perception, perhaps by sending some sort of sign or omen to the writers to stop or change their stories.
Skip Westcott could be an ordinary person who just happens to cross paths with the Avengers. Maybe he has a heart of gold and some hidden courage that the Avengers recognize.
He might be shocked. Fanfiction can often be quite different from the original source material, and the nogitsune concept is already pretty out - there. So the shock value could be high.
He'd probably be shocked. Fanfiction is not something he's used to in Asgard. He might raise an eyebrow and say something like 'What is this strange Midgardian creation?'
He might be amused. Fanfiction can be quite creative and sometimes funny, so he could just laugh it off and think it's an interesting take on the characters.
Clint would probably first be in a state of disbelief. His eyes would widen and he might take a step back. Then, as the reality sinks in, he'd break into a huge grin and rush to Coulson's side, giving him a big hug. He'd likely start asking a million questions about how Coulson survived.
In many fanfictions, Naruto's reaction is a mix of shock and determination. The shock comes from finally learning about his clan, and the determination is to uphold the Uzumaki name. He could start wearing something that represents the Uzumaki clan, like a symbol on his clothing. He also may become more protective of the Uzumaki secrets and legacies he discovers.
