Spider - Man would be super excited. He's a big fan of all things cool and different. The world of 'The Last Olympian' would be like a whole new adventure for him. He'd be asking a million questions and probably trying to make friends with the demigods right away. He might even try to learn some of their magic tricks if he could.
Captain America would probably be very respectful of the demigod's world. He's used to different cultures and values, so he'd likely try to understand their ways. Thor, on the other hand, might see some similarities between the gods in the fanfic and the Norse gods he knows. He could either be amused or a bit put off by the differences.
They would probably be very surprised. Some might laugh at the creative ideas in the fanfiction.
They could end up in some sort of team - up situation. Maybe the Avengers would see the demigods as allies against a common threat. Or they could get into a conflict because they don't understand each other's ways. The Avengers are used to high - tech battles, while the demigods fight with swords and magic. It would be a really interesting clash of cultures and powers.
For the friendship between Percy and Grover, Grover might start treating Percy a bit differently if the fanfiction portrays Percy in a new way. Maybe if the fanfiction makes Percy out to be a great leader in a more pronounced way, Grover could become more deferential to Percy, which Percy might find a bit strange at first.
He might be shocked at first. The world of the Last Olympian is so different from his own. But then he'd probably get really into it, comparing and contrasting the two worlds in his head.
If Olympians read 'The Last Olympian' fanfiction, it could be a unique experience. They could potentially find inspiration in the creative interpretations of the story. However, they might also be critical of inaccuracies in the fan - created versions of athletic events. Since they are experts in their respective sports, they would notice any deviations from the real - world rules and capabilities. For instance, if a fanfiction had a character performing a physically impossible athletic move, an Olympian reader might shake their head at it. At the same time, they could enjoy the fictional elements that add a new dimension to the story they already know from the original work.
They might be amused. Gods in Greek mythology often have a sense of humor. If they read fanfiction about their own world, they could find the creative interpretations of mortals quite entertaining.
Some would be intrigued. Captain America, being an open - minded person, might be interested in seeing different interpretations of their team dynamics. He could even gain new insights about his relationships with his fellow Avengers through the fanfiction.
Thor would likely be the most affected. He has a history with Fenrir as it is from Asgardian mythology. He might be cautious at first, but also feel a sense of kinship. Iron Man would probably be all about analyzing Fenrir, trying to figure out its weaknesses and strengths. Captain America would be on guard, ready to defend his team, but also open to the idea of Fenrir not being an enemy if proven so.
Well, when the Avengers first encounter Sephiroth, they'd be quite surprised. Tony Stark would crack a joke to ease the tension a bit but still be very aware of the danger. Steve Rogers would stand tall and be the first to step forward, showing no fear. Thor would grip his hammer tightly, ready to defend. Bruce Banner would be worried that if Hulk gets involved, it could be a very chaotic battle. The female Avengers like Black Widow and Scarlet Witch would be sizing up Sephiroth, trying to find any chinks in his armor. They'd all be on high alert and start formulating a plan to either defeat or contain this unexpected and very powerful new arrival.
Some characters might become more self - aware. If they read a fanfic that delves deep into their insecurities, they could start to face those aspects of themselves. For instance, a proud character might realize they have been too arrogant after reading a fanfic that shows their downfall due to pride.
