Well, initially the Avengers would be cautious. They've faced many strange and powerful foes before. When they first encounter Symbrock, there would be a sense of unease. Tony Stark would start making sarcastic remarks while analyzing Symbrock's capabilities. Steve Rogers would be the voice of reason, trying to keep the team focused on finding out if Symbrock is a threat or not. Wanda Maximoff could use her powers to try and sense the emotions or motives of Symbrock. And the Avengers as a whole would be ready to spring into action depending on how Symbrock behaves.
They would probably be very surprised. Some might laugh at the creative ideas in the fanfiction.
Well, Thor might be a bit shocked at first. He'd probably be amused by some of the wilder interpretations of his brother in the fanfiction. Captain America, on the other hand, would likely be confused by the whole concept as it's so different from the traditional stories he's used to. Iron Man would probably make sarcastic comments about how creative the fans are in coming up with these stories.
Some of the Avengers might be really curious. Thor, for example, might be interested in Percy's relation to the sea, as he has his own connection to water with his powers. Iron Man might be a bit skeptical at first, thinking they're just some kids with strange powers. But once he sees what they can do, he'd be impressed.
The Avengers would be shocked at first. Tony Stark would probably crack a joke about 'giant naked monsters' while quickly analyzing the threat level. Captain America would be all business, immediately assessing the situation and trying to figure out how to protect civilians. Thor would likely see the Titans as a worthy foe and be eager to engage in battle, swinging his hammer with enthusiasm. Hulk might just charge at the nearest Titan without much thought, seeing them as something to smash.
Some Avengers might be really confused at first. For example, Tony Stark would probably be intrigued yet find it a bit odd. He'd be analyzing it like he does with new tech, trying to understand the appeal and the different universes within the anime fanfiction.
Some might be amused. For example, Thor's actor Chris Hemsworth might find it funny to see the wild adventures fans write about his character. He'd probably have a good laugh at the creative interpretations.
Well, some Avengers might be flattered. For example, Captain America would probably be really touched by positive fanart showing his heroic deeds. He'd see it as a great honor that people admire him so much. Tony Stark, on the other hand, would likely be a bit more critical. He'd appreciate the creativity but might also joke about some of the wilder interpretations in fanfiction. Thor would be confused at first but then find it really amusing, especially the fanart that shows him in a more comical way.
The Avengers' reactions would be diverse. Iron Man would likely start analyzing Jormungand immediately, trying to find its weak points. Captain America would be thinking about protecting the civilians and formulating a battle plan. Meanwhile, the Hulk could see Jormungand as a new target to smash. And the female Avengers like Scarlet Witch and Black Widow would use their unique skills, either by using magic or their combat and espionage skills to deal with the situation.
Well, there could be a lot of chaos. Symbrock is a complex and often unpredictable entity. Maybe they'd initially see Symbrock as a threat and a fight would break out. But then they might realize that there's more to Symbrock than meets the eye and try to find a way to work together, perhaps to face a common enemy that's even more dangerous.
Iron Man would be angry. He'd probably use his technology to try and track Percy down. He might also start to review all the security protocols to make sure no other traitors could do the same. Thor would be more of the 'let's fight him head - on' type, but the other Avengers would have to hold him back until they have a proper strategy.
