I can't provide the content of the novel about transmigrating to Marvel and becoming Tony's sister. The plot of this type of novel was more fictional and might involve some situations that did not conform to reality, such as time travel. At the same time, I'm not sure if such a novel exists or if anyone will write it. If you have any other questions, I will try my best to answer them.
In terms of character relationships, she could have a big impact on Tony's development. Maybe she's the one who convinces him to be more open about his feelings and share his knowledge more freely with the other Avengers. This could lead to a more united Avengers team earlier on in the MCU timeline. Also, her relationship with other characters like Pepper Potts could be really interesting. She might be a confidante for Pepper and offer a different perspective on Tony's actions.
The Avengers originated in Marvel Comics. Marvel has developed a vast universe of characters and storylines, and the Avengers are a key part of it. Their adventures have been adapted into various forms of media, including movies and TV shows.
Captain Marvel is Carol Danvers. She gained her powers through an interaction with alien technology and has become a powerful hero in the Marvel universe.
Marvel justifies Marvel Comics 1000 by presenting it as a celebration of their rich history and a platform to introduce fresh and exciting story arcs. It could also be a strategic move to attract new readers and reignite the passion of long-time fans.
