They might be quite amused. For example, Thor could find the strange and magical elements in the fanfic similar to his own Asgardian adventures. He might laugh out loud at some over - the - top magical stunts described in the fanfic.
There could be a fanfiction where the Avengers watch Dr. Strange during a battle in the mirror dimension. They watch as he manipulates the strange geometry of that dimension to his advantage against a powerful enemy. This could lead to the Avengers learning new strategies from Dr. Strange and having discussions about the limits of their own powers compared to his magic.
Black Widow would be very observant. She'd notice the details about the characters' personalities in the fanfic. If Dr. Strange is portrayed as a more cunning character than in the real story, she'd be intrigued and try to figure out the motives behind such a portrayal. Also, she'd be interested in any female characters in the fanfic and how they are treated.
I'm not sure of specific titles off - hand, but you can start by looking on fanfiction.net or Archive of Our Own. There are likely many stories where the Avengers watch Dr. Strange do something amazing, like opening a portal to a different realm or using his time - bending powers in a unique way.
It's a very interesting graphic novel that combines the unique magical elements of Dr Strange with the complex and often villainous nature of Dr Doom. The art style is likely to be a major draw, with vivid illustrations that bring the strange and otherworldly settings to life.
The story of Dr Strange and the Dark Dimension is quite fascinating. He has to navigate the complex and dangerous realm of the Dark Dimension. There are all sorts of strange creatures and powerful magic there. And his struggle to keep the Dark Dimension from encroaching on our world while also dealing with the power - hungry entities within it makes for a great story. His ability to manipulate time and space within the Dark Dimension is also a very interesting aspect of this story.
In my opinion, the story from 'Doctor Strange' (2016) movie is one of the best. It shows his journey from a self - centered surgeon to a sorcerer who protects the world. His accident that led to him seeking a different path and his training in Kamar - Taj are really engaging parts of the story.
One of the best Dr Strange stories is 'The Oath'. It shows his loyalty to his oath as a sorcerer and his struggle to uphold it in difficult situations. Another great one is 'Into the Dark Dimension' which dives deep into the terrifying and mysterious Dark Dimension and Dr Strange's adventures there.
The story where Dr Strange battles Dormammu in the Dark Dimension is also great. It's a classic encounter that really showcases Strange's ability to outwit his foes. He uses his magic in clever ways and doesn't rely on brute force. This battle is iconic and has been adapted in the movies as well.
